Available in three versions the Testo 835 range of infrared thermometers are ideal for measuring temperatures at a distance due to them having 50:1 optics (5 m distance = 10 cm measurement spot diameter). All units also have a 4 point laser which shows the exact measuring position and values can be saved in the internal memory for subsequent analysis on the PC.
Features
The 835-T1 model has a measuring range of -30 to +600 oC which makes it ideal for monitoring wall temperature, troubleshooting in heating and air conditioning systems, or the quality control of industrially manufactured products.
The 835-T2 has an extended measuring range of -10 to +1500 oC which is suited to measuring temperature in the glass, ceramics and metal industries.
The 835-H1 has an integrated surface moisture measurement capability making this product ideal for detecting the risk of mould in building fabrics.
- Measure temperatures safely and accurately even at long distances
- No measurement errors, thanks to focused optics (5 m distance = 10 cm measurement spot)
- Convenient menu guidance with icons and joystick
- Save measurement data on-site and subsequently analyse it via PC
