The GD-K8A is a diffusion style toxic gas detection transmitter ideally suited to meet your toxic gas detection needs. You can choose from a wide variety of toxic sensors to install in this model. The GD-K8A is an ideal solution for many toxic gas monitoring applications. The low profile design is only 1.5 inches thick and is easy to install. The hinged housing makes it easy to maintain. This transmitter can be installed with any RKI controller, or integrated to existing PLC or DCS system via 4-20mA output (24VDC two-wire, loop powered).

The sensors for the GD-K8A are aged and tested over a one to three month period, typically resulting in a three to five year life span, providing a lower cost of ownership for your gas detection system. The sensors are robust electrochemical type that feature higher sensitivity and selectivity. Fast sensor response time and excellent stability make these sensors the most reliable and longest-life electrochemical sensors available today.

At the heart of any gas detector is the sensor. With over 65 years of sensor technology experience, RKI has the knowledge and capability to provide the most advanced detection techniques and manufacture the most stable and long lasting sensors in the world. As a result the GD-K8A is one of the most stable and long lasting toxic transmitters on the market.
