testo 835-T1 infrared thermometer

Get started in the field of intelligent infrared measuring technology. The practical infrared thermometer testo 835-T1 offers maximum safety and precision when measuring the temperature of smaller objects from a medium distance, e.g. monitoring wall temperature, troubleshooting in heating and air conditioning systems, or the quality control of industrially manufactured products.

The 4-point laser clearly indicates the measuring area and prevents incorrect measurements
The 50:1 optics allow you to carry out measurements from a long distance and still obtain excellent results (distance 5 m = 10 cm measuring spot)
The integrated degree of emission table enables you to select the correct degree of emission of the measured surface
The backlit display allows you to use your infrared thermometer in all lighting conditions

The testo 835-T1 also allows you to carry out contact temperature measurements. The thermometer is equipped with a connecting point for a wide range of optional temperature sensors. The temperature sensor can also be used to automatically measure the degree of emission of a particular surface. This makes it easier to carry out subsequent infrared measurements.

There is also a wide range of optional accessories - including a tripod and a robust carry case – that allow you to customize your testo 835-T1 infrared thermometer to suit your needs.

For easy analysis and easy use

The testo 835-T1 comes with an easy-to-follow menu, self-explanatory icons and a user-friendly joystick. Your infrared thermometer can be used to create different measuring sites or save up to 200 readings while additional features including min/max values, adjustable thresholds and visual and acoustic alarms which are triggered when thresholds have been exceeded make work more efficient and life easier. The free-to-download “EasyClimate” software provides you with a quick and convenient means of analyzing your measuring data.
