Single-input K/J thermometer

The Tenmars TM-80N is a single-input digital thermometer that accepts both K-type and J-type thermocouples. It provides a dual LCD five-digit readout with 0.1°C resolution and a basic accuracy of ±(0.05% + 0.7°C). Functions include Max, Min, Average and Data Hold plus an auto power-off timer set to fifteen minutes that can be disabled. The unit measures 130 x 56 x 38 mm and weighs about 170 g including the battery, which is not supplied.

Ideal for electricians and HVAC technicians

Suited for professionals who need a compact, single-channel instrument for spot-checking temperatures from -200 °C to 1370 °C on K-type or -200 °C to 1050 °C on J-type probes. The 24 V input protection and temperature coefficient specification support use in typical industrial environments. Users requiring simultaneous dual-channel measurement or T1-T2 differential readings should consider a dual-input model instead.

K-type range to 1370 °C

The decisive specification is the K-type upper limit of 1370 °C (2498 °F) combined with the stated ±(0.05% + 0.7°C) accuracy, which determines whether the instrument covers the highest process temperatures the user must measure.

Questions about this item

How do I connect the thermocouple probe to the single input on the TM-80N?

Plug the K-type or J-type thermocouple connector into the single input jack; ensure correct polarity so the reading is not reversed.

When will I need to replace the battery in the TM-80N?

Replace the 9 V battery when the low-battery indicator appears; the unit ships without a battery so install one before first use.

What is the highest temperature the TM-80N can measure continuously with a K-type probe?

The K-type range tops out at 1370 °C (2498 °F); above that the display will show over-range.
