SKU: RL4101

Product Description

The RL4101 is part of the 4000 range of advanced temperature and humidity radio transmitters. They allow wire-free monitoring of a site, with real time alarm notification and historical analysis of data. Each RL4101 unit reads its on-board sensors providing accurate and reliable information about environmental conditions. This data is transmitted, at user-defined intervals, to the Radiolog system where it is filed for analysis.

The RL4101 has a precision thermistor sensor and high quality humidity sensor. These sensors are housed in convenient plug mounted housings.

There are two sensor mounting options; either plug mounted or remote cable mounted. The on-board plug in sensors are used to measure over the instrument operating range. To measure over the whole range remote sensors are required.
