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.
|
A 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.. |
