A 4-point laser to identify spots! An infrared thermometer that measures accurately.
The testo 835 includes the basic model testo 835-T1, which can measure temperatures up to +600°C, the high-temperature model testo 835-T2, which can measure up to 1500°C, and the testo 835-H1, which can measure temperature and humidity (with dew point calculation). With a spot ratio of 50:1, it allows for small measurement areas even from a distance, and the four-point laser makes it easy to identify the measurement area. It is a user-friendly industrial thermometer that not only displays surface temperature but also features alarms with sound and icons, as well as a memory function. 【Features】 ■ Equipped with a 4-point laser ■ Spot ratio of 50:1 ■ Measures a 10 cm diameter area from 5 m away ■ Built-in emissivity data ■ Memory for 200 data points, recording both measurement temperature and date/time ■ Analysis possible with dedicated software ■ Contact measurements possible with a K-type thermocouple probe ■ Easy-to-understand menu screen with icon display *For more details, please download the PDF or feel free to contact us.
