Touring Transmitters with built-in temperature / RH and temperature sensors

Part of a brand new, growing product range from Eltek, the GDLM10 transmitter has built-in logging memory for storing data on the move.

10 Series


Built-in digital RH and temperature sensor.

GDLM10 - a transmitter with simultaneous logging - all in one unit

The transmitter retains all of the GenII transmitter hallmarks whilst adding in logging capabilities, with storage for approximately 52,000 readings.

User Options

The GDLM10 can be used for monitoring objects in transit, for example museum exhibits. The unit is removed from its normal location, transported with the object, and upon reaching its destination, the readings can be downloaded and optionally added into a database, for continuous monitoring.

The GDLM10 can also be used as a standalone environmental monitoring solution, with data being downloaded from the unit for analysis.

We offer a range of software compatible with the unit, depending on the user requirements.
