testo 435-3 Multifunctional measuring instrument with built-in differential pressure measurement to detect HVAC systems and indoor air quality, including battery and factory report
Product Introduction:
空气环境测量仪给你提供的环境空气测量,它有正确完善的测量探头,比如 热敏探头,叶轮或者毕托管,适用于各种风速测量和相关应用,testo 435-3 的室内空气质量探头可以通过测量CO2 Concentration, air humidity and air temperature to determine indoor air quality. Measurements of air temperature, humidity and wind speed can be made simultaneously in the new thermal probe. In addition, the instrument can be attached to an external temperature probe, for example, to accurately measure surface temperature. The disy disys readings from up to three temperature sensors. The instrument can print reports on the spot through testo Express printer
Advantages at a glance:
Indoor air quality probe for assessing indoor air quality
Thermal probe, impeller type wind speed probe to measure wind speed, through the built-in differential pressure probe and pitot tube for wind speed measurement
Testo printer to achieve on-site printing archive
