Description

The Testo 535 ambient CO2 meter uses CO2 as an indicator to assess indoor air quality. If the CO2 in indoor air is too high (>1000 ppm), the air feels stuffy and and stale and can lead to fatigue, poor concentration, and illness.

The Testo 535 ambient CO2 meter has a measuring range of 0 to 9,999 ppm CO2 with accuracies of ±(50 ppm CO2 +2 % of mv) from 0 to 5,000 ppm and ±(100 ppm +3 % of mv) from 5,000 to 9,999 ppm CO2.

The Testo 535 ambient CO2 meter comes complete with permanently attached probe, instruction manual, batteries and calibration protocol.
