HT-4801
Standard Model
| 35,800 yen and up * [tax not included] |
| 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.

| 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 | Setup unit without LINKSHIP or PC required: Program Loader PL-5A [sold separately] |
