The frequency indicator is used to display AC parameters. The frequency indicator can measure and display AC current, AC voltage or frequencies. The possibility of freely scaling the input signal allows a very versatile use of this frequency indicator.
The Air Humidity Meter PCE-P18S measures air humidity and air temperature. The Air Humidity Meter calculates the dew point and the absolute humidity from these two values. The measurement data from the Air Humidity Meter are output via the Modbus RTU interface.
