USB Type-C [standard feature]　
Data logging, setting

Easy setup, measurement and installation　Consideration for ease of use on site

Front operation. Setting and measuring

(A) Operation indicator LED
(B) Front sheet button
- [In program mode] MODE, digit selection, numeric setting, ENTER
- [In measurement mode] Span shift, Zero shift
- Key lock, etc.

Blue/pink type [Option]
*Designs are subject to change.

Mounting hooks [Left and right] For fixing the main unit

Smart configuration and logging
Setting management, report printing, and CSV logging with dedicated software LINKSHIP [free of charge]　 Go to 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	Setup unit without LINKSHIP or PC required: Program Loader PL-5A　 [sold separately]
	PL-5A Product Page *Setting only / data logging and power supply not available

Power supply: 12 to 30VDC / 100 to 240VAC　[Select a model]
Isolation　Electrical isolation between power supply / thermocouple input / other input/output

Applications　
Simultaneous temperature measurement of multiple locations
etc.
