testo 830-T4 - Laser Temperature Gun
Overview
The testo 830-T4 laser temperature gun also achieves accurate results at greater distances during non-contact surface temperature measurement. This is provided by its 30:1 optics and powerful processor. The non contact infrared thermometer measuring instrument carries out measuring tasks in trade and industry quickly and efficiently.
Product Description
Product Description
- 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
Extended functions with the connectible probe
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.
