RKI GD-81D Smart Gas Transmitter

The 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 24VDC or Power-over-Ethernet, the GD-81D operates from -10°C to +40°C in its compact wall-mounted housing — a good fit for facilities standardizing on one transmitter platform across many different point-monitoring locations rather than stocking model-specific hardware.
