atmospheric oxygen sensor | GGO 581/GOO 581/GGA 581

Product Description

atmospheric oxygen electrode for GMH 569x
for low oxygen concentrations

 

GGO 581	closed sensor type, tube adapter and T-piece incl. suitable for over and under pressure for use in gas-tight systems application: Suitable for measurements in normal atmosphere and in systems without or with slight under or over pressure. The sensor type GGO 581 has a screw thread and can be installed gas-tight in almost every system directly or with the help of a tube adapter (incl. in scope of supply).
GOO 581	open sensor type, tube adapter incl. suitable for air or gas stream quick temperature compensation application: Due to the special construction of sensor the measuring gas streams optimally around the sensor and escapes into the air through holes in the housing. At slight flow to the sensor, no pressure buil-up occurs that falsifies the results of measurement. Particularly suitable for measuring of gas of pressure cylinders, etc. Also measuring of indoor-gas concentrations is possible.
GGA 581	closed sensor type with pressure connection, tube adapter and T-piece incl. This housing is optimal for the device GMH 5695 with external pressure connection. Especially for systems with over or under pressure or at dynamic pressure due to incident flow. application: It can be screwed in airtightly (attention: please note permissible operating pressure!). The pressure connector of the device is connected to the pressure connector of the sensor. The device measures and compensates the actual pressure at the sensor.

Note: not suited for „under water“-applications (rebreather, etc.)
