The radio handle for plug-in sensor heads with TE adapter impresses with its easy handling and international approvals (USA, CA, CL). Radio frequency: 915.00 MHz FSK.

The Testo 635-2 is an instrument designed for measuring air moisture, material equilibrium moisture and pressure dewpoint in compressed air systems. Moisture characteristics can be recorded in the instrument memory and analysed and displayed in graphics or tables. Precision probes up to -60&deg;C tpd are available to check pressure dewpoint in compressed air systems.&nbsp;

Use the compact professional humidity module to carry out wireless humidity/temperature measurement with the appropriate radio handle and measuring instrument (both available to order separately).

The humidity module can be attached to various Testo radio handles. It enables a high level of accuracy thanks to the precise humidity sensor.<br />
<br />
Wireless handle (0554 0189) and wireless module (0554 0188) are required to use a radio probe, and these can be ordered optionally.
