Heat-Prober
®
Thermocouple Thermometers and Probes are
rugged and reliable instruments made for process and
maintenance temperature measurements.
The pocket-sized microprocessor-based Heat-Prober Type K
thermometer updates readings three times per second with an
accuracy of ±0.2% of reading ±1 digit in 1°F or °C resolution.
The precision cold junction is compensated with a unique,
permanently calibrated circuit.
The Wahl Maxi-Temp peak hold switch, available on all models,
permits the Heat-Prober to hold and display the highest
temperature reached. This function is ideal where the operator
must concentrate on the probe when making the measurement
and where an instantaneous transient peak is to be recorded.
Maxi-Temp meters also can be switched to normal operation.
Advanced electronics are housed in ABS plastic, thoroughly
tested for environmental integrity and subjected to 4-foot drop
tests, battery life and running life tests. All units are calibrated
with simulated EMF inputs and powered during a high-
temperature burn-in cycle.

probe, and accessory money-saving kits.

NIST TRACEABLE THERMOCOUPLE CALIBRATORS
This thermocouple meter
accessory allows
calibration over the
meter’s full range.
Useful for quick field
diagnostics, it assures
meter accuracy whenever
a measurement is in
question.
Accuracy is ±0.3°F/°C or
0.2% of reading,
whichever is greater.
User sends the calibrator
only back to the factory
for NIST Certification.
One Calibrator maintains
NIST traceability for all
in-house meters.
