RKI GD-81D Smart Gas Transmitter hydroponics Whether you're using augersThe RKI GD 81D is a sample draw smart transmitter built on a common sensing platform compatible with 300+ existing RKI sensor types, letting one wall mounted housing cover combustible gas, a wide range of toxics, oxygen, or CO2 depending on the sensor installed. An internal pump draws roughly 0. 5 L min, and dual 3 wire or 2 wire 4 20mA outputs pair with Ethernet (10 100BASE T) connectivity and dry contact relays for flexible integration. Powered by
