  • Extended temperature range for reliable measurements up to 2,732 °F

  • IR measurements from a safe distance; precise measuring of moving objects

  • Memory of up to 200 readings; easy analysis with free to download software

  • 4-point laser and 50:1 optics for precise measurements over greater distances

The testo 835-T2 infrared thermometer reveals just what it’s made of, long after other infrared thermometers have given up. The testo 835-T2 allows you to measure temperatures up to 2,732 °F, and moving objects, safely and reliably.


Product Description

Ideal for use in the glass, ceramics, or the metal industry, the testo 835-T2 high temperature infrared thermometer is the ideal professional tool for a wide variety of thermal applications in the high temperature range. It has an extremely wide temperature range, for thermal measurements up to 2,732 °F, and can be used to measure small, hard to reach, moving, or very hot objects from a safe distance.
  • 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 15 ft. = 4 in. 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-T2 can also be used to carry out contact temperature measurements. It has 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 allows you to customize your testo 835-T2 infrared thermometer to suit your needs.

For easy analysis and easy use

The testo 835-T2 comes with an easy to follow menu, icons, and a user-friendly joystick. It can be used to create different measuring sites, save up to 200 readings, and record min/max values. The adjustable thresholds and visual and acoustic alarms make work more efficient, and life easier. The free to download software provides you with an easy means of analyzing your data.

Product temperature monitoring for quality control in glass, ceramics and metal industries up to 1,500°C

The testo 835-T2 is ideally suited for product quality assurance for various industrially manufactured products: e.g. in the production process to determine whether the required temperature has been reached for further processing of the product, or when cooling products.

Advantages of the testo 835-T2:

  • Fast and precise measurement from a safe and long distance
  • Integrated emission level table and automatic determination of the emission level enable a rapid selection of the right emission level for various surfaces
  • Clear marking of the measuring range by 4-point laser
  • Possibility of monitoring and logging the temperature profile by long-term measurement (only in combination with EasyClimate PC software, a free download via testo.de)
