     - 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.
