Geonor - Model M-603 Series -Open Push in Electrical Pore Pressure Gauges

The M-603 is a special version of the M-600, which is open to atmosphere and equipped with a rubber membrane over the pressure membrane. Using compressed air, a back pressure is applied to relieve the pressure membrane. This will balance against the pressure during depressurization and thus the pore pressure gauge can be depressed faster. The back pressure can also be used to relieve the membrane for reading the zero point frequency. Only available for standard cable and for maximum 6 bar.
