Testo 435-2 Data Logging Air Quality Monitor, +1370 °C, +150 °C, +400 °C Max, 100%RH Max, Battery-Powered

The Testo 435-2 data logging air quality monitor is a multi-functional measuring instrument for ambient 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 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 velocities such as thermal probes, vanes and pitot tubes.
Note:
Wireless temperature probe system requires one wireless module to be plugged into the 435 instruments and up to 3 wireless thermocouple probe handles each fitted with a Type-K thermocouple probe head for surface temperature measurement, range -50°C to 350°C.
Probe to be ordered separately, that is 512-0755 etc.
Supplied with:
Batteries carry strap and instructions.
This is the main unit without probes - for fitting probes kindly check the datasheet.
