CALOG - TC
The CALOG - TC is a high precision,
multi-functional, hand-held calibrator
suitable for the process control industry. It’s
speciality is thermocouple based
instruments. It measures and sources,
thermocouple, millivolts and milliamps. It
can measure DC Volts and continuity. The
trend feature is ideal for graphing
temperature profiles and PID controller
optimization. It’s small size, long battery life
and high precision make the
CALOG - TC ideal for industrial field or
workshop calibration.
Measures and sources types: J, K, T, E, R,
S, B and N Thermocouples. Configurable
internal or manual cold-junction
compensation, in either °C, °F, Kelvin or
Rankine. Accuracy is better than 0.5°C,
excluding cold junction errors and
thermocouple errors. The CALOG - TC has
a resolution of 0.1°C. Measures and sources
-10 to 100mV with 0.01% accuracy and 1µV
resolution.
It can simultaneously source a thermocouple
and measure mA (isolated). The trend
feature is useful for temperature graphs or
controller optimising.

CALOG Calibrators
The CALOG range of process instrumentation calibrators are designed for servicing, repairs in the workshop and
the plant environment. They are tough, sophisticated precision instruments that are portable, compact and userfriendly.
Robust enough to withstand the rigors of most industrial environments, they are powered by long-life Nickel
metal hydride batteries, monitored by ‘fuel gauges’ and incorporate a clear, back-lit graphic display.
For quick source value set-up, the CALOG uses the “key-per-digit” numeric setting feature that enables the user
to scroll each digit up or down.
The graphic display can be selected to display the measured value or trend with programmable time base.
