Riken Keiki – GD-70D. Intelligent Fixed Gas Monitor

The GD-70D Intelligent Fixed Gas Monitor has exceptional performance, flexibility, and versatility. The GD-70D has an array of sensor technologies that are unmatched in the industry. There a many toxic gas options. There are also hydrogen-specific as well as LEL versions.

The long life high capacity pump and sensors are easily and quickly replaceable. With no special tools required.

Plug and Play Smart Sensors :

The smart sensors retain all calibration as well as sensor-specific data in non-volatile memory.  The sensors can therefore be hot-swapped in the field with no programming required. In addition the sensors also retain calibration information, which means they can be conveniently calibrated separate from the Monitor.  This avoids having to transport of calibration gases to the field location. The GD-70D firmware automatically corrects for long-term zero in addition to span “drift” minimizing maintenance and maximizing reliability.

The GD-70D can be used as a stand-alone device as well as offering a number of communication protocols to existing PLC systems. Users also integrate it with single and multi-channel controllers.

Maximum Flexibility :

The GD-70D Intelligent Fixed Gas Monitors have a large, easy to read integral LCD display. They have a tri-color bar graph for visual notification of alarm status, programmable low as well as high alarm relays, and a fault relay. Pump flow is self-tuning.  It has maintenance-free operation therefore. All GD-70D base units are identical. Users can Change sensors without the need for  programming or tools. This results in maximum user flexibility .

These Monitors are very popular being used in high numbers throughout the world. Users have many years of reliable as well as trouble free service.

The GD-70D is an industry standard in semiconductor fabs and factories worldwide. They have applications  in battery room monitoring as well as anywhere where toxic gases are present . See links to complementary instruments below.
