With the testo 830-T4 laser temperature gun you will be well equipped for non-contact surface temperature measurements in industry and trade. It is especially distinguished by its 30:1 optics, which also enables the laser temperature gun to record extremely small measuring spots at a great distance. This therefore allows moving or dangerous objects to be measured from a safe distance. 
 
 All key advantages of the laser temperature gun at a glance. The laser temperature gun with laser measurement spot marker not only measures the surface temperature accurately, but also quickly (2 measurements a second). Benefit from these and other advantages of the non contact infrared thermometer:
     - High resolution processor provides accurate results (resolution 0.1 °C) 
     - 30:1 optics enable great accuracy at great distances on small objects being measured (1 m distance = 36 mm measuring spot diameter) 
     - Laser temperature gun with 2 point laser measurement spot marker: the measuring point can be precisely defined (= surface between the two laser points) 
     - Two limit values that can be defined as required 
     - Visual and acoustic alarm if limit values are exceeded 
     - Min./max. temperature display and hold function (to “freeze” a certain measured value) 
    -  An external temperature probe can be connected, e.g. to determine the emission level of the surface, or for additional contact temperature measurement 
     - Convenient operation (even with just one hand) thanks to the gun-style design 
     - Clear, legible display with background lighting 
 
Furthermore, the laser temperature gun delivers extremely fast results with a speed of two measurements per second. This means that extensive surface temperature scans are also easy to handle. 
 
Extended functions with the connectible probe, An optional external temperature probe to carry out contact measurements can also be connected to the testo 830-T4 laser temperature gun in addition to the non-contact IR measurement (e.g. for control purposes). There are a range of thermocouple probes available for temperature measurements of air, liquids, semi-solid media, and surface temperatures. 
 
The comparative contact measurement with a surface temperature probe will help you determine the emission level of the surface material which helps you set the laser temperature gun emission level accordingly in order to achieve the best results in the subsequent IR measurement. 
 
In case of surfaces with an extremely low emission level, we recommend using either an emission tape (optional), or the connectible contact probe (optional) throughout the measurement.

  3. Min./max. value display and hold function: The min./max. display shows the highest and lowest values from the last measurement. This allows for safe, reliable monitoring of the product temperature. You can keep the last measured temperature values on the display by using the hold button
  4. 6:1 optics and 1 point laser measurement spot marker: The 1 point laser marks the centre of the object being measured during infrared measurement. The 6:1 optics of the infrared thermometer is suitable for measurements at closer to medium distances.
  5. In every respect HACCP: The infrared penetration thermometer is HACCP-compliant and certified in accordance with EN 13485. This makes it perfect for the food sector
  6. Practical accessories included: testo 826-T4 is equipped with the robust, watertight TopSafe protective case compliant with protection class IP67. If necessary, the TopSafe case can be cleaned in the dishwasher. The supplied frozen produce pre-driller even allows you to measure the core temperature of frozen foods. Safe storage of the HACCP thermometer is ensured by the wall/belt holder and the protective probe cap for the penetration probe.

Delivery Scope

Testo 810 IR thermometer with integrated NTC temperature sensor, including protective cap, calibration protocol, belt pouch, and batteries

IR Thermometer - testo 810
Model No: testo 810 Part No: 0560 0810

Testo 810 IR thermometer allows the simultaneous measurement of the air temperature and surface temperature of the object being measured - without contact particularly suitable for use in the heating, ventilation and air conditioning trade.

  1. Display of the temperature difference
  2. Adjustable emission level
  3. Simultaneous measurement of the surface temperature and air temperature
  4. Non-contact measurement of the surface temperature (infrared thermometer)


Testo 810 IR thermometer measures the temperature on two channels. On the one hand, being an infrared thermometer it can take non-contact surface temperature measurements of the object being measured; on the other hand, it can measure the air temperature using its additionally integrated NTC sensor. The IR thermometer displays the temperature difference directly on the illuminated display.
Functions and applications of the testo 810 IR thermometer
The testo 810 IR thermometer is extremely well suited to use in heating, ventilation and air conditioning technology. At the touch of a button, you can measure the surface temperature of radiators, air vents, or windows and compare these to the air temperature.
The compact size of the infrared thermometer makes it easy to store in your pocket and immediately accessible for taking measurements. When measuring surface temperatures, you can mark the required spot with the integrated 1 point laser to achieve a specific measurement. The 6:1 optics of the infrared temperature measuring instrument is primarily suitable for measurements at closer to medium distances.
The IR thermometer emission level can also be individually set. This allows you to adjust it to the respective material properties of the surface being measured, as well as achieve the best measurement results. The integrated air temperature sensor is also highly reliable: this is an NTC temperature sensor which measures the air temperature with utmost accuracy.
Other practical features of the IR thermometer are the min./max. display and the hold function (to record measuring values). A protective cap and belt pouch (included in scope of delivery) add to the safety of the infrared thermometer.
