The Testo 635 thermo hygrometer offers quick and easy humidity, equilibrium moisture, and pressure
dew point measurements. Compatible with wireless probes, the Testo 635 thermo hygrometer combines
advanced features with proven reliability to deliver measuring confidence in the most demanding
applications.
Wireless probes offer many advantages over traditional cable or integrated probes. There is no risk
of damaging or tangling wires or cables and measurements up to 65 ft. are possible. With the Testo 635
thermo hygrometer, 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 Testo 635 thermo hygrometer model. For wireless use, a wireless module, wireless handle, and
wireless probe is required. These are available as accessories.
Whether using wireless or standard probes, the Testo 635 thermo hygrometer uses humidity and temperature
readings to determine a wide range of air moisture measurements. All are displayed on the large, backlit
display for easy viewing including differential and mean values. Three function buttons provide access
to advanced instrument features. Ten material characteristics curves are programmed into the Testo 635
thermo hygrometer to help determine equilibrium moisture.
The Testo 635 thermo hygrometer offers several options for viewing, managing, printing and analyzing data.
The Testo 635-2 thermo hygrometer includes memory for up to 10,000 readings and ComSoft3 Compact Software
for analyzing data in graphics and tables. The optional Testo printer provides wireless infrared printing
of all channels for fast and convenient on-site documentation.
The Testo 635 thermo hygrometer is rugged by design and able to stand up to daily measuring tasks. The
rubberized housing, offers protection against dirt and impact, and will help protect your instrument. The
Testo 635 thermo hygrometer is also equipped with a convenient carrying strap plus two powerful magnets in
back that allow secure hands free operation.
