All HVAC measurement parameters
The multi-function measuring instrument testo 435 is your reliable partner for analyzing Indoor Air Quality. Indoor Air Quality has a crucial influence on the well-being of humans at their workplaces, and is also a determining and important factor in storage and production processes. In addition to this, the Indoor Air Quality signals whether the HVAC system is working at optimum energy level, or needs to be adjusted using the testo 435. The parameters CO2, relative humidity and room temperature are available for the evaluation of Indoor Air Quality. In addition to this, absolute pressure, draught, Lux, U-value and surface temperature can be measured. For the determination of volume flow, you can use all possibilities for the measurement of flow velocity - such as thermal probes, vanes and Pitot tubes.

Improved convenience of operation thanks to user profiles
The operation of testo 435 is easy and efficient: User profiles are stored for the typical applications duct measurement and IAQ measurement. This makes complicated programming of the measuring instrument unnecessary.
Secure measurement data monitoring
The measurement data reports provide the customer with the data from the duct, long-term and degree of turbulence measurement. The company logo can be integrated into the form.
Flexibility thanks to wireless probes
In addition to classical probes on wires, a wireless measurement up to a distance of 20 m (without obstruction) is possible. Damage to the wire or hindrances in usage are thus eliminated. A maximum of three wireless probes can be recorded and displayed with testo 435. The wireless probes are for the measurement parameters temperature and, depending on the instrument type, humidity. The optional, easily plugged-in radio module can be retrofitted at any time.

Supplied with: PC software, USB data cable, incl. calibration protocol and batteries
