Upper electrode allows moisture to penetrate through to the dielectrical layer and is both condensate and dirt-proof Reliable long-term humidity measurement Today’s professional humidity measurements require a reliable and precise humidity probe. The internationally patented Testo humidity probe guarantees accurate and reliable longterm measurement results everytime.
Wireless probes offer versatility Wireless probes offer many advantages over traditional cable or integrated probes. Measurements up to 65 ft. are possible. There is no risk of damaging or tangling wires or cables. With the testo 635, up to three wireless probes can be read and displayed at once for temperature and humidity measurements. The optional, easily installed wireless module can be retrofitted at any time in either 635 model.
Introducing the Rugged enough for testo 635 Series everyday use The remarkable testo 635 instruments offer easy humidity, equilibrium moisture, and pressure dewpoint measurements in seconds. Five probe inputs ensure maximum flexibility: 2 via cable connection and 3 via wireless connection. All are displayed on the large, backlit display for easy viewing including differential and mean values. Three funciton buttons provide access to advanced instrument features.
Superior data communcation and handling The 635 offers several options for viewing, managing, printing and analyzing data. Simply print out data with date and time for conveninet and fast documenation onsite with the optional testo infrared printer Meausure and store from 1 to over 10,000 readings and analyze them via Testo’s ComSoft3 Compact Software (included with the 635-2) in graphics and tables, or export the data to a spreadsheet for further analyses at a later time.
