testo 535 CO2 detector

CO2 detector Testo 535

Replaced by testo 440 CO2 with Bluetooth

The testo 535 CO2 measuring instrument is ideal for use in air quality monitoring, for example in offices. You can also see if your already installed air conditioning and ventilation system is supplying enough fresh air to all rooms.

Long-term stable, maximally accurate, 2-channel, infrared sensor measures the CO2 concentration in the room air. With the testo 535 you can even perform long-term measurements without any problems because it has a 2-channel, maintenance-free infrared sensor. For long-term measurements, you analyse the measurement results using the measured min, max and average values, which can be recalled at any time at the touch of a button.

With the optional testo Quick Printer, you can print the measured data including date and time directly at the measurement site. The optional TopSafe case optimally protects the device from dust, dirt and impact.
