The RKI GD-81D is a wall-mounted sample-draw gas detector for combustibles, oxygen, carbon dioxide and a wide range of toxic gases, including vaporized hydrogen peroxide. Plug-and-play smart sensors keep their calibration data, one unit can monitor two toxic gases, and it accepts more than 300 sensors from the GD-70D series.
- Monitors combustibles, O2, CO2 and a wide range of toxic gases, including VHP
- M sensor unit monitors two toxic gases in one detector
- Accepts more than 300 existing GD-70D series sensors
- Plug-and-play smart sensors retain calibration and sensor data
- Auto flow adjustment keeps sampling stable when a filter clogs
- Quiet low-vibration RP-80 pump; push-in quick tube connections
- Front access, tool-free sensor and pump replacement; large LCD
- Outputs: 4-20 mA analog (2- or 3-wire) or Ethernet with PoE (GD-81D-ETD)
The sensor unit (U, F or dual-gas M) and target gases are chosen when you order. Request a quote for pricing and availability.
