Testo 440 Indoor Comfort ComboKit with Bluetooth
The Testo 440 Indoor Comfort ComboKit is a measuring instrument set for assessing indoor air quality and thermal comfort in line with EN ISO 7730 and ASHRAE 55. It measures CO2 concentration (0 to 10,000 ppm), air temperature, relative humidity and air turbulence, and can derive wet bulb temperature, dew point and draught risk.
The kit pairs a base Testo 440 instrument with a Bluetooth CO2/temperature/humidity probe and a turbulence probe on a fixed cable, plus a carrying case and USB cable for data transfer. Up to 7500 measurement protocols can be stored in the internal memory.
It runs on 3x AA batteries for about 12 hours of continuous vane measurement and operates across a -20 degC to +50 degC range, suiting HVAC commissioning and workplace comfort surveys.
