testo 835-T1 – IR thermometer with small measuring surface and 4-point laser
The testo 835-T1 is the standard model of the 835 series, suitable for general temperature measurements with both non-contact IR technology and with standard probes for insertion and contact measurements. It ensures maximum safety and precision when measuring temperatures on small objects, even from considerable distances. Such as control measurements on specific wall or house sections, troubleshooting of heating and air conditioning systems, safety checks of electrical installations or quality control in various industrial processes.
You can also use the testo 835-T1 to log measurement values when connected to a PC via USB cable, thanks to the testo EasyClimate software. The picture shows curves of IR temperature values and temperature values from a connected type K thermocouple sensor.
A summary of the benefits:
- Safe measurement at long distances thanks to 50:1 optics
- Clear 4-point laser sight shows exactly where to measure
- Combi instruments – non-contact IR measurement and contact measurement with sensors
- Adjustable alarm limits
- Memory for measured values and locations, and data analysis on a PC
- Clear backlit display
