Portable Compressed Air Dew Point Meter

Sigma 500 series portable compressed air dew point meters

The new Sigma 500 series is an ideal portable service instrument for dew point measurement for all types of driers down to -80°Ctd dew point.
The 3.5" graphic display with touch screen makes the operation very easy.
The graphic indication of colored measuring curves is unique.
Ideal for measurement of the current dew point and for graphic indication of the dew point curve/the switching behavior of the drier over a longer period of time.
Up to 100 million measured values can be stored with date and measuring site name.
The measured data can be transferred to the computer via USB stick.

Special Features:
Precise dew point measurement  down to -80°Ctd
Fast response time
Graphic display/easy operation  via touch screen
Integrated data logger for storage of the measured values
USB interface for reading out the  data via USB stick
Calculates all required humidity parameters like g/m³, mg/m³,    ppm V/V, g/kg, °Ctdatm
