The testo 400 IAQ and Comfort Kit with Tripod is a complete, high-precision kit tailored for HVAC and indoor air quality professionals focused on workplace comfort and environmental compliance. At its core is the testo 400 universal IAQ measuring instrument, capable of capturing all key climate parameters including air velocity, temperature, humidity, CO₂, CO, and pressure.

This kit enables standard-compliant comfort level assessments in accordance with EN ISO 7730 and ASHRAE 55, measuring PMV (Predicted Mean Vote), PPD (Predicted Percentage of Dissatisfied), draught, and turbulence. It includes a CO₂ probe with Bluetooth® handle, a turbulence probe, and a 150 mm globe thermometer—all designed to work seamlessly with the provided measuring tripod for proper probe positioning and repeatable results.

The system supports long-term IAQ monitoring when paired with the separately available IAQ data logger, which allows continuous data collection for up to two weeks even without the handheld instrument. Coupled with digital probes to eliminate measurement uncertainty and powerful data analysis/reporting software, this kit delivers everything you need for accurate and efficient IAQ and comfort assessments.
