Testo 835-H1 Infrared Thermometer With Humidity Module
The Testo 835-H1 is a versatile non-contact measurement tool designed to simultaneously measure surface temperature (-50 to +600 °C) and humidity, making it ideal for detecting thermal bridges, mold risks, and energy losses in buildings, as well as monitoring HVAC systems and industrial processes.
Equipped with a built-in humidity module, 4-point laser aiming, and a 50:1 optical resolution for remote measurements, this thermometer combines precision with user-friendly operation. It stores 200 measurement sets, features adjustable emissivity for diverse surfaces, and includes customizable alarms and a backlit display for enhanced usability in any environment.
- Dual Measurement Capability: Measures surface temperature (-50 to +600 °C) and relative humidity (RH). Calculates dew point, dew point distance, and surface moisture (aw value) for mold risk assessment.
- Precision & Remote Sensing: 4-point laser aiming pinpoints measurement areas to avoid errors. 50:1 optical resolution enables safe remote measurement (e.g., 5m distance = 10cm measurement spot).
- Adjustable & Customizable Functions: Emissivity adjustment (0.10 to 1.00) for accurate readings on metals, plastics, wood, etc. Customizable upper/lower limits with sound-light alarms for immediate defect detection.
- Data Management & Storage: Stores 200 measurement sets with customizable location tags. Backlit display with 30-second auto-off for visibility in low-light conditions.
- Ergonomic Design: ABS + PC housing for durability in industrial environments. Joystick and button controls for intuitive operation. Compact size (193 x 166 x 63 mm) for easy handling.
- Expandable Capability: Connectable external temperature probes for low-emissivity surfaces (optional).
