Product Details
Low dew point probe Reliable measurement of micro moisture
The low-temperature dew point probe adopts the latest Airchip4000 technology, together with Hygromer ® Together with the LDP-1 dew point sensor, the measurement results are calculated from the average of 8000 points within a 2-second measurement interval, providing the highest quality measurement solution.
Application field
Low temperature dew point probes can be used in compressed air systems, freeze dryers, and adsorption dryers. The probes provided by Rotronic come with EX certification and meet ATEX requirements.
Attachment
By using a suitable sampling chamber, the air flow can be limited to the optimal dew point measurement point, and a quick connection interface is provided. There are two materials to choose from, POM and stainless steel, which can be customized. .
- Highly accurate dew point temperature measurement
- Capable of withstanding pressure up to 100 atmospheres
- Hygromer ® LDP-1 sensor
- Good repeatability
- Monitoring trace amounts of moisture in restricted environments
- Latest Airchip4000 measurement technology
- Compatible with HF5/HF8/PF4 transmitters and HP22/HP23 handheld devices
