AIR QUALITY CO2 METER
 

535 Air Quality CO2 measurement
Testo 535, the ideal CO2 measuring instrument for building engineers. Bad air quality in enclosed rooms which is caused by a too high CO2 concentration (> 1000 ppm) can lead to tiredness 
lack of concentration and even to illness (sick building syndrome SBS.)
Air Quality CO2 Meter CO2

The advantages at a glance.

  • Long-term monitoring using maximum 
    value and mean calculation

  • 2 channel infrared sensor

  • long-term stability

  • high accuracy

  • highly reliable

  • repeated adjustment unnecessary

 

The accurate CO2 measuring instrument for building engineers.

  • 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

  • Practical accessories:

    Topsafe (indestructible protective case) wall holder for quickly positioning the measuring instrument with probe
