1370M Series Heat Prober Hand Held Type K Thermocouple Meters, °C


1370M Series handheld thermocouple type K meters have a temperature range of -70° to 1370°C and display in °C only.  Meter accepts all type K thermocouple probes with ANSI mini-connectors.

The pocket sized 1370M series models use a microprocessor to update temperature readings 3 times per second with an accuracy of ±0.2% of reading ±1 digit with 1°C resolution.  The precision cold junction is compensated using a unique, permanently calibrated circuit.

Units are calibrated with simulated EMF inputs and powered during a high temperature burn-in cycle.  Choose from models with LED or LCD screens, and will rechargeable NiCad or standard alkaline battery.  All NiCad models come with a battery recharger.
