The testo 400 is the universal measuring instrument for all IAQ professionals. Measure, analyze and document all IAQ and comfort level parameters using just one instrument – simply, conveniently and in compliance with the standards. High-quality measuring technology, intuitive measurement assistants, versatile documentation options and a comprehensive selection of IAQ probes make the testo 400 the perfect partner for your day-to-day work.Ideal kit for IAQ professionals, with a focus on indoor air quality and comfort level. You will receive the testo 400 universal IAQ measuring instrument with intuitive measurement menus, one CO₂ probe (with Bluetooth^® handle), one turbulence probe and one globe thermometer Ø 150 mm (both with fixed cable). Use the measuring tripod to ensure standard-compliant positioning of the probes. In combination with the IAQ data logger, which is available to order separately, long-term measurements up to 2 weeks can be recorded, even without the IAQ measuring instrument.Ideal kit for IAQ professionals, with a focus on air flow measurement. You will receive the testo 400 universal IAQ measuring instrument with intuitive measurement menus, one vane probe head (Ø 16 mm), one vane probe head (Ø 100 mm) and one high-precision humidity/temperature probe head – all three can be attached to the Bluetooth^® handle supplied. For measurements at ceiling outlets, simply combine the 100 mm vane probe with the telescope (can be extended up to 1.0 m) and the 90° angle.Ideal kit for IAQ professionals, with a focus on air flow measurement. You will receive the testo 400 universal IAQ measuring instrument with intuitive measurement menus, one hot wire probe head (including temperature and humidity sensor), one vane probe head (Ø 100 mm) and one high-precision humidity/temperature probe head – all three can be attached to the Bluetooth^® handle supplied. For measurements at ceiling outlets, simply combine the 100 mm vane probe with the telescope (can be extended up to 1.0 m) and the 90° angle.Reliably and precisely evaluate heat load at workplaces: In combination with the universal IAQ measuring instrument testo 400, the kit allows you to determine the Wet Bulb Globe Temperature (WBGT). The kit is ideal for use in the steel and construction industries, at sports events and at workplaces with high heat irradiation.

Heat load at workplaces: In order to be able evaluate the length of time a person can remain at a health-hazardous workplace, the WBGT index (Wet Bulb Globe Temperature) is recommended.

With the WBGT kit, you are best equipped for the evaluation of heat-affected workplaces based on ISO 7243 and DIN 33403-3. The kit is ideal for determining the Wet Bulb Globe Temperature – because it can be used to precisely measure all relevant climate parameters such as humidity temperature, ambient/air temperature and radiant heat.
