Dew Point Meter with integrated IP67 aluminium die-cast housing
The FA 550 is ideally suited for outdoor dew point measurement and reliably determines dew points even under harsh industrial conditions.
Dew Point Display Values
Other Humidity Parameters
The integrated display shows the dew point in big figures as well as further humidity parameters on two more display pages. By means of the arrow key it can be browsed between the display pages.
Alarm Threshold Freely Setting
Selectable Measuring Units
The alarm threshold value for the integrated relay can be entered via the keys. Apart from the alarm threshold it is also possible to enter the hysteresis freely.
The alarm could be set to one of the values (units)
