atmospheric oxygen electrode for GMH 369x
for low oxygen concentrations
GGO 381
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 381 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 381
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 381
closed sensor type with pressure connection, tube adapter and T-piece incl.
This housing is optimal for the device GMH 3695 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.)
