Why so many Heat-Prober® Meters?
Meters are the basic component of a Heat-Prober System. Probes, no matter how well designed and
constructed, will not compensate if the wrong meter is chosen for the job. Wahl Heat-Probers are
offered in three basic measurement types:
Platinum RTD
Platinum Resistance Temperature Detectors (RTD’s) are recognized as the most reliable standard for
measuring temperature information. Platinum provides long-term stability, response and repeatability
for use as a primary standard. It has a wide useful temperature range and can be used in varying
conditions, making it ideal for many applications.
Thermocouple
Thermocouple portable temperature sensors have the advantage over other types due to their fast
response, wide temperature range, and ruggedness. The sensors are small in size, versatile and
convenient to use. An added advantage of thermocouple use is derived from their wide-spread
availability and meter/probe compatibility.
Thermistor
Thermistor sensors offer excellent accuracy and long-term stability, but over a relatively narrow
temperature range. Thermistors are generally used to measure moderate temperatures in applications
demanding greater accuracy than thermocouples, but less demanding than Platinum RTD Thermometer
Systems.
Each type has advantages and characteristics described in the catalog sections to follow. Basically the
differences center on accuracy, temperature range, type of display and price.

What is a Heat-Prober®?
Wahl pocket-sized digital Heat-Probers are complete, high
performance portable temperature measurement systems. Wahl
originated the systems approach to provide engineers,
technicians and research scientists the high confidence required
for “routinely critical” temperature measurement.
A Heat-Prober “system” consists of a meter and a sensing probe.
The Heat-Prober meter serves (by means of a microprocessor) to
accurately interpret the temperature sensed by the probe, provide
digital output and allow measurement options such as peak
reading hold or maximum/minimum memory. The meter also
contains the power (battery) to allow complete system portability.
Heat-Prober probes are designed to be interchangeable. This
allows a meter/probe system to be formed with any number of
probes for specific applications used interchangeably with the
meter. More probes for additional applications or replacement
probes may be purchased, or an additional or replacement meter
can be utilized without replacing existing probes.
Portability and Ruggedness
A Heat-Prober’s battery power and rugged compact design make
them the perfect choice for service and maintenance technicians
who must use their temperature measurement equipment on the
move and in a variety of tough environments. Kits with userselected probes are available for many of the meters. HeatProbers store away in small spaces without special requirements.
Versatility
Wahl offers Heat-Prober meters utilizing platinum RTD,
Thermocouple and Thermistor technology. Many meters offer
range, display and kit options. All meters have a full set of
interchangeable probes carefully designed and built to perform
specific measurement tasks. This approach allows Heat-Prober
users maximum versatility in specifying, purchasing, utilizing and
maintaining a temperature measuring system suited to their
needs.
Accuracy
Cost Effectiveness
Because of the Heat-Prober meter’s microprocessor, the probe’s
sensor can be linearized to yield maximum accuracy at all points
within the measuring range. Probe design is
also a large factor in accuracy. The ability
to select a standard or custom probe
specific to the task and constructed from
superior materials, is a key in “system
accuracy.”
Buy meters and interchangeable probes specifically for your
applications and needs. Replacement and additional probes can
be purchased as required.
Service
Wahl maintains a complete calibration lab with NIST traceability.
This service allows your Heat-Prober meters, probes or systems to
be calibrated at standard or user-specified points. Wahl also offers
repair service for meters and probes.

RTD Meters
392A Series
Platinum RTD Probes
392A Series Platinum
RTD Probes
Platinum resistance temperature detectors (RTD’s) are recognized
worldwide by metrology laboratories as the most reliable standard for
measuring and comparing temperature information. Platinum provides
long-term stability and repeatability for use as a primary standard. It
has a wide useful temperature range which makes it ideal for
laboratory and industrial applications.
Our accurate, stable platinum sensors are housed in thin wall stainless
steel shanks with low mass tips that don’t compete with the measured
object. That’s why Wahl probes have fast response, and provide an
accuracy of ±0.2°F at ice point, ±0.5% of reading thereafter.
Every probe is engineered to do a specific job in measuring surfaces,
liquids, semi-solids or gasses. Each probe has a high quality, heatresistant Delrin® handle, a coiled 5-foot cord and a snap-in connector
that mates it solidly to our thermometer (exceptions noted in
descriptions below).
Every probe is calibrated at two or three temperature points on NIST
traceable secondary standards and tagged “Wahl Test Certified” with
calibration data. You can order a NIST certificate with test data for
meters and probes. See page 6.

Wahl Platinum-RTD Probes Are
Interchangeable Without
Recalibration
For surface probes where it is necessary to bring the greatest
amount of surface heat in direct contact with the sensor, a unique
design developed for the U.S. Space Program is employed. The coil
is bonded to a platinum base plate of low thermal resistance which
contacts the measured surface. The platinum base, in turn, is
bonded directly to a thin stainless steel, bell-shaped housing of low
mass. Heat loss is impeded by high thermal resistance elements:
stainless steel housing, shank and coil spring.
The coil spring in Wahl 121 and 145 surface probes
provides automatic articulation of the tip for conformity
and uniform contact with the surface being measured.
This is especially useful in blind recesses where contact
measurements are made by “feel” instead of sight.

Thermocouple Meters
Type K Probes
Type K Thermocouple Probes
Probes for High Performance
The quality of temperature measurement depends principally on the probe design as it relates to the
object being measured. That’s why each of Wahl’s interchangeable thermocouple Type K probes is
scientifically engineered to do a specific job.
Wahl thermocouple probes are designed for the fastest response possible depending upon use.
Each starts with the thermocouple junction, precision welded for virtually instant response. Then a
stainless steel sheath is created with a thin wall for fast measurements or a thicker wall for heavy
duty applications. Surface probe tips are Wahl-engineered to provide optimum contact with the
least thermal load.
Portable probes have (except as noted) rugged Delrin® handles, ANSI mini-connectors and 5-foot
flexible compensated cables.
These probes are compatible and interchangeable for use with Wahl Heat-Prober Meters 2500/1370
series (page 10), TM410, and TM500 (page 11).
Calibration Traceable to NIST
All thermocouple probes are individually calibrated at two temperature points to the same NISTtraceable secondary standards and tagged with calibration data. Probes are calibrated with your
purchased meter or with a factory maintained standard, so you get guaranteed precise
temperature measurements in the harshest environments.
Thin wall 300 series stainless
steel sheath results in fast
probe response.
Rugged Delrin® handle
withstands high temperatures.
Flexible compensated
cable takes abuse.
Type K ANSI miniconnector plugs
solidly into
thermocouple
meters.
Look for the “Wahl Tested
Certified” calibration tag on
every probe.
