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.


Measurement -270°C to +1820°C
Measurement resolution 0.1℃/1℃

Rate setting between two points Linear correction formula

Smart configuration and logging
Setting management, report printing, and CSV logging with dedicated software LINKSHIP [free of charge]  > LINKSHIP page

CSV logging Compare and match set value lists PC save and copy of set values Prevention of misoperation Quickly set up multiple units
Time-specified logging, such as 600 seconds, is also available. Custom logger software is also available. Multiple lists of set values can be compared and collated. It prevents errors in note-taking and manual entry, and reduces management effort and costs. Settings and confirmations can be made on the PC screen, preventing misoperation of the main unit's buttons. Even multiple units can be easily configured by simply writing the configuration data.

USB Type-C connector standard: configuration, logging, power supply   Setup unit without LINKSHIP or PC required:
