Mold Risk Assessment Kit

The Mold Risk Assessment Kit is a powerful, professional solution for viewing mold-prone areas, combining the advanced capabilities of the testo 860i Wireless Thermal Imaging Camera and the testo 605i Bluetooth Thermohygrometer. Designed for HVAC professionals, facility maintenance, and building inspectors, this kit enables accurate detection of insulation deficiencies, high humidity levels, and areas susceptible to mold growth

The testo 860i Thermal Imaging Camera features a high-resolution 256 x 192 pixel infrared sensor, providing razor-sharp thermal images to detect cold spots and insulation issues. The testo 605i Thermohygrometer measures air temperature and humidity, calculating dew point and wet bulb temperatures to identify conditions that promote mold growth.

Through seamless Bluetooth connectivity with the Testo Smart App, users can view real-time thermal images, document results, and generate professional reports directly from their smartphones. This enables easy data analysis, ensuring timely action against potential mold risks.

Built for tough environments, the testo 860i is IP54-rated, drop-resistant (1.5m), and equipped with a long-lasting rechargeable battery, making it a reliable tool for on-site use. Ideal for surveyors, facility maintenance, and HVAC professionals, the testo 860i Mold Kit provides a comprehensive, smart, and efficient solution for preventative maintenance and mold risk assessment.
