Testo Data Logging Air Quality Monitor

The Testo 435-4 data logging air quality monitor is a multi-functional measuring instrument with built-in differential pressure measurement for air conditioning, ventilation and indoor air quality, with data memory, PC software and USB data transfer cable includes battery and calibration protocol. The indoor air quality has a crucial influence on the well-being of humans at their workplace 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 velocities such as thermal probes, vanes and pitot tubes.
