OS 215 & OS 220

The dew point sensors OS 215/OS 220 provides reliable and long term stable dew point monitoring in industrial applications. With these models dew point measurement in refrigerant dryers becomes affordable and can replace traditional temperature measurement which often couldn’t tell the real dew point. OS 215/OS 220 outputs the measurement value through the loop powered 4-20 mA signal.
