testo 635-2 - Temperature and moisture meter
Order-Nr. 0563 6352
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°C tpd are available to check pressure dewpoint in compressed air systems.-
