testo 435 - Indoor Air Quality Surveys

 

The testo 435 IAQ multi-function instrument, is ideal for evaluating and diagnosing indoor air quality (IAQ). Addition of an optional built-in micromanometer makes it perfect for testing/adjusting HVAC systems. It is available with over 50 different probes, including wireless probes for remote sampling.

The 435 measures temperature, humidity, CO2, CO, dewpoint, air velocity, differential pressure, lux, absolute pressure, surface temperature and u-values (R-values). Determining volume flow is easy using the pitot tubes, vane probes or thermoanemometer probes. The testo 435 can measure differential pressure across filters, coils and pressurised rooms.

A valuable option is the unique wireless probes which allow simultaneous measurement of temperature and humidity from up to 65 feet away. These probes operate with the same accuracy as traditional cabled probes and the probes integrated into the instrument, without tangled wires or the need to repeatedly access inconvenient locations. Up to 3 wireless probes can be read and displayed at once and the optional wireless modules can be installed by the user at any time.

The 435 is available in four versions, ranging from the basic 435-1, a standard IAQ and HVAC multifunction meter, to the 435-4, the most advanced, compact meter in the family.


Large memory capacity is able to safely store 10,000 readings which can be downloaded and analyzed later for diagnostics and audits..Use the ComSoft3 software for analysis, filing and documentation of data. The 435 will print to an optional IR printer.
It can also perform timed interval printing, from 1 minute to 24 hours, set by the user.
