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).
