Testo 535 CO2 Meter with Extendable Probe for IAQ Consultants & HVAC Engineers
The testo 535 CO2 monitor for IAQ and ventilation surveys - checks the work environment for conditions that contribute to "Sick Building  Syndrome," Quickly evaluates air exchanges rates.

The testo 535 is the easiest way to measure CO2 for indoor air quality (IAQ) surveys. Poor air quality in rooms can lead to tiredness, lack of concentration and illness (Sick Building Syndrome) due to high CO2 concentration (greater than 1000 ppm).

Advantages at a Glance

  Accuratge & efficient method to monitor & evaluate indoor air quality in offices 
  Measures the concentration of CO2 from diffusers and return air ducts
  Tests stationary CO2 transducers in 'demand controlled' ventilating systems
  Long-term monitoring with maximum and mean calculations
  Highly stable sensor makes repeated calibrations unnecessary
  Quickly print data on portable testo printer
