What is the Testo 835-H1 Infrared Thermometer with Humidity Measurement?
The Testo 835-H1 is an advanced infrared thermometer designed for HVAC engineers, building surveyors and maintenance technicians who need accurate surface temperature measurement combined with humidity analysis.
With 50:1 optics and 4-point laser targeting, it delivers precise non-contact temperature readings from a safe distance, even on small or hard-to-reach surfaces. The integrated humidity module enables surface moisture detection, helping identify condensation risk and potential mould issues in buildings, making it ideal for HVAC diagnostics, building inspections and maintenance work.
How does the Testo 835-H1 improve diagnostics on site?
The Testo 835-H1 combines infrared measurement with humidity analysis to give a clearer picture of environmental conditions. Its patented surface moisture measurement helps detect problem areas early, while adjustable emissivity ensures accurate readings across different materials.
With built-in memory, PC software compatibility and intuitive menu navigation, it allows technicians to log, analyse and report measurement data efficiently. The option to connect Type K probes (sold separately) adds flexibility for contact temperature measurement when required.
Why is surface moisture detection important in HVAC and building inspections?
It helps identify condensation risk and hidden damp issues early, reducing the risk of mould growth and improving building performance and safety.
