Testo 440 CO2 Kit
Part Code :
0563 4405


With the Testo 440 CO₂ kit with Bluetooth®, all IAQ-related
parameters for evaluating indoor air can be measured and documented wirelessly. The Testo 440 air velocity & IAQ measuring instrument recognizes probes automatically, and its structured measurement menus simplify the adjustment of air conditioning and ventilation systems. Up to 3 probes can be connected simultaneously to the measuring instrument: a Bluetooth® probe, a wired probe and a temperature probe with Type K thermocouple connector.

- Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO2 concentration, humidity and air temperature in indoor areas
- Precise: absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
- Convenient: wireless probe, internal data storage and USB port for data export
- As multifaceted As your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes

Major Applications
- Long-term monitoring of indoor air quality
- Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55
- Convenience and maximum flexibility for duct and outlet measurements
