Testo 6621 Temperature and Humidity Transmitter

Overview

The Testo 6621 measurement transmitter stands out thanks to its patented humidity sensor, which guarantees the highest accuracy. It is designed for reliable, continuous temperature and humidity monitoring in HVAC, building-services and light industrial applications, delivering stable analog output signals for control and monitoring systems.

Particularly practical: the sensor and analog outputs can be adjusted, analysed and parameterised via an external interface using the testo P2A software, making commissioning and maintenance straightforward. Housed in a compact ABS wall-mount enclosure, the testo 6621 combines high accuracy with easy integration into building-management systems.
