Testo 835-H1 Infrared Thermometer with Humidity Module
Product Introduction
The Testo 835-H1 is a professional-grade non-contact measurement tool designed to simultaneously measure surface temperature (-50°C to +600°C) and relative humidity. Equipped with a humidity module, 4-point laser aiming, and a 50:1 optical resolution, it enables precise detection of thermal bridges, dew points, and surface moisture—ideal for building diagnostics, HVAC maintenance, and industrial quality control. The device stores 200 measurement sets, features an adjustable emissivity function, and includes a backlit display for use in low-light environments.
