Testo 435-2 - Multi-function Instrument for VAC & IAQ
With readings memory, PC software and USB data transfer cable, includes battery and calibration protocol
The measuring instrument for ambient air conditions, for assessment of Indoor Air Quality and adjusting and testing VAC systems, stands out on account of its efficient measurement process. Probe-controlled menus and selectable user profiles, e.g. for duct measurement or long-term measurement, ensure the user-friendliest operation possible. The IAQ probe measures Indoor Air Quality by measuring the CO2 level, air moisture and air temperature. In addition, the lux probe and comfort level probe can be connected to assess draught air. Clear analysis and archiving ensure practical PC documentation. Temperature and humidity measurement is integrated in the thermal probe. The special flow protocol professionally documents duct measurements. It is also possible to connect additional temperature and humidity probes. Readings from up to 3 temperature or humidity probes can be clearly displayed in the measuring instrument; data transmission is by radio, i.e. wireless.
- Instrument memory for 10,000 readings
