IR radiation in your sights - infrared thermometer with targeting laser

For the safe measurement of hot or cold surfaces. Particularly suitable for rotating machines. On models with a single laser beam, only the measuring direction can be seen. Devices with two beams or circular lasers also provide information about the perfect measuring distance and the actual size of the measuring spot at a specific distance. This prevents incorrect measurements due to incorrect operation.

Recognizing the risk of mould before it develops

Moisture condenses easily on cold surfaces. Humidity and surface temperature play a role here. Moisture then begins to condense above the so-called dew point.

In addition to the surface temperature, these measuring devices also determine the dew point and thus the risk of mold growth.

Temperature measuring devices with maximum accuracy

The PTM series delivers very accurate readings. Although the temperature range is not as wide as that of K-type measuring devices, the PTM devices deliver impressive accuracy within the specified measuring range. Thanks to the PT1000 measuring resistor used, the resistance of the connecting cable is negligible and the IP65 protection is a further advantage of this series in practice.
