Basic Type K or J Thermometers provide accurate temperatures for a wide range of applications. These pocket-sized thermometers accept Type K or J thermocouples with standard connectors. The temperature range for Type K is -328°–2,498°F (-200°–1,370°C), and Type J is -328°–1,922°F (-200°–1,050°C).

Features include Maximum/Minimum memory hold, auto-power, and relative temperature functions that offer top accuracy. The four-digit LCD display switches between °C and °F and the accuracy is ±0.05% of reading +0.7°C (1.4°F).

Select from a single or dual channel model, and models with a "T" suffix include a NIST traceable certification of calibration.

Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
