- Sampled air that is adulterated with oil or water mist or dust can damage the product.
(Sampling air filtration quality: particulate filter degree: 0.3 µm or finer, oil concentration: 0.8 wt ppm or lower.) - Due to the fixed orifice, the flow rate of the sampling air does not have to be adjusted by the user.
- Always use a low water absorption fluorine tubing such as PTFE or PFA for the sampling air piping. (Included part: 3 m of fluorine tubing.)
- Displays dew point under operating pressure.
- There are 2 sets of alarm output contacts. (Operates with standby sequence.)
- The precision of displayed dew points of –80 to –60 ℃ are not guaranteed values and are for reference only.
- In order to assure precision, it is recommended that the dew point sensor be calibrated approx. every two years.
- Automatic Dew Point Sensor Cleaning Function: Note that new measurements will not occur during the sensor cleaning process, and during that time, the last measured value will be displayed. (The display will automatically return to normal after the cleaning process.)
