Thermocouple Meters
2500/1370 Series

2500/1370 Series Type K Thermocouple Meters

• 2500 Meter Range -100° to 2500°F
• 1370 Meter Range -70° to 1370°C
• Meter options for °F or °C range, display type and power
• Meter accuracy is ±0.2% of reading ±1 digit
• Maxi-Temp®automatically holds peak reading
• Accepts all type K probes with ANSI mini-connectors
• Microprocessor circuitry for thermocouple linearization

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 hightemperature burn-in cycle.
Model 2500M (-100° to 2500°F) features a bright .33″ high red LED display for normal to low lighting conditions. It operates on a rechargeable 6.25V NiCad battery pack. Includes battery recharger/AC line adapter and Wrist Strap.

See Meter specifications on page 12. NIST TRACEABLE THERMOCOUPLE CALIBRATORS TA-70AFK Precision Calibrator in use with 2500MX Thermocouple Meter
NIST Certification is optional with Calibrator
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.

TM410 Thermocouple Food Service Thermometer

TM410 with TCL329K Extension Handle allows use of interchangeable probes with one handle and cord set. See page 15 for probe descriptions.
The Wahl TM410 Type K Thermocouple Digital Heat Prober® Thermometer is economical and compact. It provides the highest accuracy at the lowest price of any Thermocouple Instrument on the market today.

• Accuracy of ±1.0°F (±0.5°C) in an operating range of 32° to 200°F (0° to 93°C)
• Meets and exceeds FDA Requirements (Food Code requires ± 2°F)
• Optional probes plug into the top of TM410 for easy single-handed use
• Optional TCL329K Extension Handle for extended reach
• Built in pocket/belt clip on back of unit
• Reduced dirt-harboring crevices for easy cleaning
• °F and °C Switchable

TM410 shown in use with NIST Certified TA50AFK Calibrator, page 10.

Wahl TP Probes (shown left with TM410, described on page 15) are specially manufactured with food service in mind to give fast and accurate results. They can be inserted into the TM410 for single handed operation and are durable enough to withstand the rigors of a busy kitchen. Probes can be safely passed through the dishwasher for ease of cleaning. Accuracy is maintained regardless of which probe is attached, assuring greater certainty of safe food temperature, and tighter control over the quality of the finished product.

TM500 Thermocouple Meter

The Wahl TM500 Heat Prober Meter offers value with exceptional features. The TM500 has advanced microprocessor functions, dual display and dual probe capability for more advanced testing in critical process and laboratory applications.

• TM500 Type J Range of -328°F to 1922°F (-200°C to 1050°C).
• TM500 Type K Range of -328°F to 2498°F (-200°C to 1370°C).
• Large LCD and Dual probe input accepts one or two Type J or Type K Thermocouple probe(s) with standard ANSI mini-connectors.
• Selectable temperature scale, Fahrenheit or Celsius readings.
• Main LCD displays the temperature reading from either selected probe or the temperature difference between the two.
• Third LCD displays time or timing duration (hours, minutes, seconds) of MAX/MIN or AVERAGE temperature events.
• “Recording” mode allows data storage for MAX, MIN, and AVERAGE temperatures reached over a time period.
• “Set” mode allows entry of reference and alarm points.
• Supplied with water and shock resistant rubber boot, built-in easel stand, 9V battery, and two Type K test probes.
