The Swiss manufacturers of precision measurement instruments ROTRONIC has launched new low dew point probes for precise measurement of temperature and low dew point in pressure environments. The probe and its accessories are pressure resistant up to 100 bar. The measurement range covers -70…85 °C Td /-40…85 °C.

The low dew point probe comes with the latest AirChip4000 technology. Calculates a measurement from the average of 8,000 single points within a 2 second interval and, together with the HYGROMER® LDP-1 dew point sensor, delivers measurements of the highest quality. The low dew point probe is in sintered stainless steel and compatible with ROTRONICs transmitters and handheld instruments such as HF5, HF8, PF4, HP22 und HP23.

In addition it can be connected with the HW4 software for monitoring and hardware configuration and validation.

Field of Application The low dew point probe can be used in compressed air systems, refrigeration driers and adsorption driers. ROTRONIC offers the probe with EX certificate for environments with ATEX requirements.
