Highly accurate CO2measurement
Long-term stable 2-channel infrared sensor
Long-term monitoring thanks to max. and mean value
calculation
No necessity for repeated adjustments
Bad air quality in indoor rooms due to excessively high CO
concentrations (greater than 1000 ppm) leads to tiredness,
lack of concentration and can even cause illness.
testo 535 is a precise, reliable CO
monitoring Indoor Air Quality. The high-quality and stable
2-channel infrared sensor allows long-term measurements,
and does not require repeated adjustment.
