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. Advanced electronics are housed in ABS plastic, thouroughly 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.The result is a thermometer so durable and reliable that it comes with a 3-year warranty. Meter range is -100 to 2500°F. Features a bright .5" high red LCD display for normal to bright lighting conditions. The 2500MXX operates on a rechargeable 6.25V NiCad battery pack.
