Product Description

Specially designed for HVAC, the FHT20 series by Focusens is a cost effective, highly accurate and reliable solution for measuring relative air humidity and temperature.

The enclosure minimizes installation costs and provides outstanding protection against contamination and condensation, thus ensuring flawless operation.

The FHT20 employs the new humidity / temperature Sensirion sensor element SHT21 with excellent long term stability and resistance against pollutants. In combination with a long calibration experience, the FHT20 provides a measurement accuracy of ±3%RH and is available for wall-mounted with current, voltage output.
