Thermocouple meter HTL-2401 [Temperature Meter]
| Compatible with various thermocouple[TC] types K, J, R, E, T, B, N, S |
Select a TC type and measure the temperature.
The electromotive force corresponding to the temperature difference between the tip of the TC and the main body of the instrument
is measured as a voltage and converted to a temperature.
