Description
InWater TGP Sensor Cartridge
The TGP sensor cartridge is the replaceable, consumable core of every InWater TGP probe. Because the probe measures Total Gas Pressure through membrane diffusion, the membrane and internal cartridge are a wear item that should be serviced periodically — InWater recommends cartridge service after each month of continuous deployment — to keep readings accurate and response times fast.
Keeping a spare cartridge on hand means a fouled or aging probe can be back in service in minutes rather than being sent out for a full rebuild, which matters most during active monitoring windows around spillways, pump stations, or production cycles when you can’t afford a gap in your TGP data.
Compatibility
- InWater TGP probe (all cable lengths: 5 m, 7 m, 15 m, and custom)
- Used with the InWater Tracker handheld meter, TGP Transmitter, and RIU3 installations
