Center 340 Thermo Recorder - temperature datalogger

CENTER 340 is a temperature datalogger.
Even though these units are focused on data collecting, we placed a LCD to show the operator on site information.

In case of dark environment, it is also equipped with backlit display. Both units feature a real time clock inside so that the event are captured with time stamps.
The recording memory can hold up to 64000 records which can provide high resolution test results.

With waterproof housing, the temperature datalogger 340 has a lot of applications such as environmental monitoring, food transportation process monitoring, or air condition monitoring, etc.

The data is downloaded through IR photo interface so the connector is not damaged by water.
