About Data Loggers

Q1: Where can I find the registration code and serial number?

The registration code can be found on the supplied label, or by opening the back cover of the logger as shown in the pictures below.
The serial number can be found on the same label as the registration code, or on the bottom of the logger.

Q2: Is it possible to extend the length of the sensor?

The TR42 sensor can be extended by using our optional sensor extension cable “TR-2C30".
(The cable length is 3 meters and one cable can be used per TR42 sensor.)
