testo 830-T4 infrared thermometer
With the testo 830-T4 infrared thermometer, you are ideally equipped for non-contact surface temperature measurements in industry and trade. It stands out in particular due to its 30:1 optics, with which the infrared temperature measuring instrument can detect very small measuring spots even at long distances. This means that moving or dangerous objects can be measured from a safe distance.
All the advantages of the infrared thermometer at a glance
The infrared thermometer with laser spot marking not only measures the surface temperature precisely, but also quickly (2 measurements per second). Benefit from these and other advantages of the infrared temperature measuring device:
- High-resolution processor ensures accurate results (resolution 0.1 °C)
- 30:1 optics enable high precision for long distances and small measurement objects (1 m distance = 36 mm measuring spot diameter)
- Infrared thermometer with 2-point laser spot marking: measuring point can be precisely defined (=area between the two laser points)
- Two freely definable limit values
- Visual and acoustic alarm in the event of limit violations
- Min/max temperature display and hold function (to "freeze" a specific measured value)
- An external temperature sensor can be connected, e.g. to determine the emissivity of the surface or for additional contact temperature measurement
- Convenient handling (even with just one hand) thanks to the pistol design
- Easy-to-read digital display with backlighting
The infrared temperature measuring device also delivers very fast results, as up to two measurements per second are possible. This means that even extensive surface temperature scans can be mastered with ease.
Extended functions thanks to connectable probe
You can optionally connect an external temperature probe to the testo 830-T4 infrared thermometer if you want to carry out a contact measurement in addition to the non-contact IR measurement (e.g. for control purposes). Thermocouple probes are available for temperature measurements in air, liquids, semi-solid media and for surface temperature measurements.
The comparative contact measurement with a surface temperature sensor also helps you to determine the emissivity of the surface material. This allows you to set the emissivity of the infrared thermometer accordingly in order to achieve optimum results in the subsequent IR measurement.
For surfaces with very low emissivity, we recommend either using an emissivity tape (optional) or using the connectable contact probe (optional) during the entire measurement.
