The testo 830-T1 infrared temperature gun with laser measurement spot marker and 10:1 optics is suitable for non-contact surface temperature measurements in trade and industry. 
Overview of the advantages of the testo 830-T1 infrared temperature gun :
testo 830-T1 infrared temperature gun facilitates fast and accurate non-contact measurement of the surface temperature (2 measurements a second). To summarise, the infrared temperature gun offers the following advantages: 
-    High resolution processor for utmost accuracy (resolution 0.1 °C) 
-    10:1 optics for precise measurements even at medium distances 
-    IR thermometer with 1 point laser measurement spot marker to target the measuring point 
-    Two alarm limit values that can be defined as required 
-    Visual and acoustic alarm if limit value exceeded 
-    Min./max. value display and hold function (to record a measured value) 
-    Convenient one-handed operation thanks to the ergonomic gun-style design 
-    Clear, illuminated digital display 
The speed of the testo 830-T1 infrared temperature thermometer is impressive: it can take two measurements per second that helps you undertake bigger measuring tasks quickly and efficiently. 
 
For infrared temperature gun, the emission level can be individually set. This allows you to adjust it precisely to the surface of the material being measured, to achieve the best possible measurement results. For untreated surfaces with a low emission level, we recommend using an emission tape (optional) which makes the IR temperature measurement significantly easier.

The testo 830-T2 IR thermometer with laser measurement spot marker and 12:1 optics is suitable for non-contact surface temperature measurements in trade and industry. 
Overview of the advantages offered by the testo 830-T2 IR thermometer :  
With the testo 830-T2 IR thermometer, non-contact measurement of surface temperature is accurate and fast (2 measurements per second). To summarise, the IR thermometer offers the following advantages: 
-    High resolution processor for utmost accuracy (resolution 0.1 °C)

The speed of the testo 830-T2 IR thermometer is also very impressive: it can carry out two measurements per second. This means you can undertake bigger measuring tasks quickly and efficiently. 
 
In addition to infrared measurement, the testo 830-T2 infrared thermometer also offers the option of carrying out a contact measurement. Simply connect an optionally available TC type K temperature probe to the infrared measuring instrument. Testo offers a large selection of probes: e.g. a fast-action surface probe with sprung thermocouple strip, but also air probes or immersion/penetration probes (for liquids and pastes). 
 
The IR thermometer emission level can be individually set. This allows you to adjust it precisely to the material of the surface being measured to achieve the best possible measurement results.

Laser Temperature Gun - testo 830-T4
Model No: testo 830-T4 Part No: 0560 8314

The testo 830-T4 infrared temperature gun equips you for efficient, non-contact surface temperature measurements for undertaking control measurements in trade and industry.

  1. Laser measurement point marker and large optics for exact measurement even at greater distances Fast recording of measurement values at two measurements per second

  6. Distance to measurement spot 30:1
  7. Measurement spot marking 2-point laser
  8. Contact external thermocouple (TC type K) for contact type Measurement


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.
