A fast, timesaving, and reliable true temperature calibrator
designed for on-site use. The CTC series is a fast dry-block
that offers both interchangeable inserts, the MVI stability
circuitry, and calibration software. Both speed and portability
are superior to liquid baths. Dry-block calibrators do not
require hazardous liquids and provide a wide temperature
range.
Calibrate your RTD’s, thermocouples, thermoswitches,
thermistors, and other common temperature sensing
devices.
Fast calibration is timesaving
The specially designed heating block
profile heats up to 320°C / 608°F in just
4 minutes and to 650°C / 1202°F in only
10 minutes.
High flexibility
You are not limited by fixed holes. Interchangeable insertion tubes are used
to match the diameter of your sensorunder-test.
Enhanced stability
MVI circuitry ensures stability despite
mains supply variations in the process
environment.
Timesaving features
Fast one-key-one-function access to the
automatic switch test and auto stepping.
Documentation made easy
RS232 communication interface and
AMECAL-LIGHT calibration software
package are part of the standard
ISO 9001 Manufacturer
PRODUCT DESCRIPTION
The CTC series is designed for both on-site and maintenance shop use.
The applications are generally critical process control but can vary based on
calibration and testing requirements. The user interface is easy and intuitive.
One-key-one-function gives you quick access to timesaving features such as
the switch test or the auto-stepping function. All models feature a large, backlit
LCD display panel, which is easy-to-read even in well-lit areas. Units feature
an informative display that provides icons and information regarding the status
of the CTC and the calibration in-progress. The JOFRA CTC series consists of
six different models that differ in temperature ranges and immersion depths. All
units offer similar features. A rugged, slim-line, aluminum outer casing with diecast top and bottom protects the CTC series of dry-block calibrators. For easy
documentation and automatic calibration, all units are delivered with RS232
serial communication and AMECAL-LIGHT PC calibration software.

Fast heating and cooling
The CTC-320A and the CTC-650A contain an innovative
heating block profile. This design heats up the CTC-320A to
maximum temperature in just 4 minutes and the CTC-650A
in only 10 minutes. The fast performance of the heating block
is due to the special profile that minimizes mass and yet, still
accepts an insertion tube with a 25 mm / 1 in. outer diameter.
This design is a balanced compromise between temperature
stability / homogeneity and rapid heating / cooling.
SS-CP-2281-US
inconsistently leading to both inaccurate readings and unstable temperatures.
The CTC series apart
from the CTC-140A
employ the MVI, thus
avoiding such stability
problems. The MVI
circuitry continuously
monitors the supply
voltage and ensures a
constant energy flow to
the heating elements.
The CTC-140A does not require the MVI circuitry because the
Peltier elements are energized with a stabilized DC voltage.
Easy-to-use, intuitive operation
Deep immersion depth
The model CTC-320B and CTC-650B models offer a deeper
immersion depth of 200 mm / 7.9 in. If you have liquid-filled
sensors or other sensors that require a deeper immersion
depth, look for the B versions. While the units do not heat and
cool as quickly as their shorter counterparts, they offer the
capability to accommodate longer sensors.
CTC-140A heating/cooling block
The model CTC-140A features Peltier elements. In 1834,
Jean Peltier, a French physicist found that an ’’opposite
thermocouple effect’’ could be observed when an electric
current was connected to a thermocouple. Heat would be
absorbed at one of the junctions and discharged at the other
junction. This effect is called the ’’PELTIER EFFECT’’.
All instrument controls may
be performed from the front
panel. The heat source is
positioned away from the
panel. This design helps to
protect the operator.
The main functions on the
CTC series are designed
with one-key-one-function
logic. This means that there are no sub-menus or difficult to
remember multiple keystrokes necessary to access primary
functions.
The easy-to-read, backlit display features dedicated icons,
which help in identifying instrument conditions and operational steps.
�
Set temperature
The ’’Up’’ and ’’Down’’ arrow keys allow the user to set the
exact temperature desired with a resolution of 0.1°C or °F.
Instrument setups
The CTC series stores the complete instrument setup,
including: engineering units, stability criteria, resolution,
display contrast, slope (ramp) rate, auto step settings, and
maximum temperature.
High accuracy at high temperatures
The CTC-1200A contains a unique designed well with the
internal sensor placed in the specially drilled inserts and
a non-linear heating element. In combination with the MVI
circuitry this design ensures high accuracy and excellent
stability when calibrating different sizes of sensors without
use of an external reference sensor.
The CTC-1200A offers an immersion depth of 110 mm / 4.3
in. for calibrating sensors up to a diameter of 12 mm / 1⁄2 in.
Besides these advantages the CTC-1200A is smallest in its
class and thereby easy to carry into the process.
MVI - Improved temperature stability
MVI stands for ’’Mains power Variance Immunity’’.
Unstable mains power supplies are a major contributor to
on-site calibration inaccuracies. Traditional temperature
calibrators often become unstable in production environments
where large electrical motors, heating elements, and other
devices are periodically cycled on and off. The cycling of
supply power can cause the temperature regulator to perform
Stability indicator
The bold checkmark on the display indicates that the
calibrator has reached the desired set temperature and is
stable. The operator may change the stability criteria and
establish a greater sense of security in the calibration results.
A convenient countdown timer is activated five minutes before
the unit reaches stability.
Automatic switch test
Operators can save a lot of time using the automatic thermoswitch test function to find values for the ’’Open’’ and ’’Close’’
temperatures. Additionally, this feature displays the hysteresis
(deadband) between the two points. The feature ensures a
very high repeatability when testing thermo-switches. Simply
press the »SWITCH TEST« key to activate the function.

Auto-stepping
Simplified calibration documentation
This feature saves manpower. The operator may stay in
the control room, or another remote location, monitoring
the output from the sensor-under-test while the CTC series
calibrator is placed in the process and automatically changes
the temperature using a programmed step value and rate.
Up to 9 different temperature steps may be programmed,
including the hold time for each step.
This feature is also ideal for burning-in new sensors prior to
installation: This minimizes initial drift and allows for initial
testing. It is also useful for testing temperature data loggers.
All JOFRA CTC instruments are supplied with
RS232 computer interface
and the AMECAL-LIGHT
Calibration software.
This WINDOWS®-based
software allows the user
to customize his or her
calibration routines. The
software is easy to use so
you do not have to be a
programmer to configure your own calibration procedures.
After calibration you can print out certificates that contain all
necessary information for your ISO-9000 or similar quality
systems. The AMECAL-LIGHT
software supports automatic
calibration for all JOFRA dryblock calibrators equipped with
an RS232 serial data interface
including the JOFRA
DTI-1000 digital thermometer.
For semi-automatic calibrations,
the software also supports
liquid baths, ice points, or other
dry-block heating and cooling
sources. Using the software’s
’’SCENARIO’’ function allows
for combining instruments in
virtually any configuration.
�
�
Maximum temperature
From the setup menu, the user can select the maximum
temperature limit for the calibrator. This function prevents
damage to the sensor-under-test caused by the application of
excessive temperatures.
Re-calibration/adjustments
The CTC series has a very easy and straight forward
procedure for re-calibration/adjustment. There is no need for
a screwdriver or PC software. The only thing you need is a
reliable reference thermometer. Place this reference probe in
the calibrator and follow the instructions on the display.
Liquid filled sensors and switches
The tall B models with an immersion depth of 190 mm / 7.5 in.
are ideal for calibration of liquid filled sensors. The specially
designed non-linear heating elements in the CTC-650B and
the increased block mass provide a very homogeneous
temperature throughout the block. It is essential for the quality
of the calibration/test that the full lenght of the sensing part
of the sensor is exposed to the same temperature. Calibrate
analog reading devices or switches with very high repeatability.
Upgrade to the AMECAL-TEMPERATURE software and be
able to store all your results in a certificate database, sensor
database and instrument database and use the database
function history and search.

if you buy undrilled inserts.
The heat shield protects the sensor/transmitter under test
from the heated air.
Use the cleaning brushes to clean the borings in your inserts
when necessary.
Insulation tube and plates
Improve your calibration
uncertainty by insulating
the sensor-under-test.
Minimize the heat dissipation from the top of
the block and through the
sensor-under-test. This
insulation is important for
all dry-block calibrators
without the dual-zone
heating block.
Carrying case
The optional protective
carrying case ensures
safe transportation and
storage of the instrument
and all associated equipment.
Heat shield
An external heat shield
is available and may
be placed on top of the
calibrator to reduce the
hot air stream around the
sensor-under-test. This
is especially important
for testing thermocouples
having head-mounted
transmitters with coldjunction compensation.
