Testo Testo 535 Gas Detector for Carbon Dioxide Detection

The Testo 535 is an efficient CO₂ measuring instrument for measuring indoor air quality. Bad air quality in rooms can lead to tiredness, lack of concentration and illness and is caused in many cases, by insufficient ventilation. CO₂ is used as an indicator when assessing indoor air quality – if the CO₂ in indoor air is too high (limit value: 1000ppm) the air feels stuffy and stale.

Long-term monitoring via maximum/mean calculation
2 channel infrared sensor
Long-term stability
Tests stationary CO₂ transducers in ’demand controlled’ ventilating systems (DCV)
Monitors indoor air quality in open plan offices
Measures the concentration of CO₂ in ingoing and outgoing air ducts
Data can be printed on location with date and time on the optional IR Testo printer
