Product Description

Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument, the CO2 probe with Bluetooth® including temperature and humidity sensor and the turbulence probe are all safely stowed away in the case. So you can get down to work straight away! Products in set
