testo 835-H1 Infrared measuring instrument with 4-point laser marking, measurement data management function and humidity module, including battery and factory report
Product Introduction:
testo 835 series products can be used in all relevant professional and industrial fields to full advantage: such as monitoring wall temperature and humidity, checking air conditioning and ventilation systems, maintaining industrial systems, or quality control of industrial products
testo 835-H1 is a special instrument in the 835 series with comprehensive surface humidity measurement function. With its unique patented infrared surface moisture measurement function, you can detect the critical point of mildew within a building structure as early as possible, measure humidity, or check the dew point distance. Users only need one instrument to complete the temperature, humidity, dew point and other parameters measurement and record and archive. Suitable for many applications in HVAC, property management, nt or building construction
Tetu infrared measurement technology can achieve first-class results even in remote conditions, especially for temperature monitoring of small, moving, hard to reach or very hot objects. The numerous features of the technology help increase the flexibility of the application, thus helping the user to control all aspects and ensuring that quality standards are met at all times
