RKI Instruments has been making high quality gas detection and monitoring units for over 15 years. With an emphasis on safety and reliability, RKI Instruments excels at providing the best products in gas detection and sensor technology on the market. Every year, RKI strives to improve its product offering and scours the globe for the latest technologies and innovative designs. With the introduction of the GD-70D Series Intelligent Gas Detector, employers and workplace safety managers can feel confident that they have purchased a reliable detector that is built to last.

GD-70D Series Intelligent Gas Detector

The GD-70D Series Intelligent Gas Detector is a new smart gas detection transmitter that monitors combustibles, oxygen, and a wide range of toxic gases. The unit can be used as a standalone device, integrated with other PLC systems, or integrated with RKI's Beacon series of single and multi-channel controllers. Its common platform integrates numerous detection methods and requires very little maintenance.

Exclusive Features

The plug and play intelligent sensors make for easy setup and calibration by internally retaining calibration and sensor data. This allows workers to replace sensors while in the field without the need to reprogram the equipment. For little maintenance and optimal reliability, the internal technology automatically adjusts for long-term zero and span drift. The pump flow is also self-tuning for low maintenance functioning. In general, the smart sensors use electrochemical cell detection, semiconductor detection, pyrolysis-particle detection, galvanic cell detection, and catalytic combustion detection.

The GD-70D Series features a large LCD display that easily reads all notifications and provides a color coded graph for alarm status (first and second alarms are red, and fault alarms are yellow). The LCD screen displays the pyrolyzer connection, gas concentration, detection unit of measurement, the detected gas, the maintenance status, sensor identification, the flow rate, a graph of gas concentration, error codes, and alarm points. All operational settings are completely user adjustable from the front panel. The unit also has a self-diagnosing function which detects sensor trouble and system failure. The Intelligent Gas Detector has a convenient troubleshoot feature through its firmware. This allows users to investigate and resolve their own equipment issues while minimizing maintenance costs.

Specifications

The Intelligent Gas Detector is a convenient size for workplace and wall space efficiency with dimensions of 2.8D x 4.7H x 5.9D and weighs approximately 2 pounds. It can be mounted to a wall easily with a base plate and 2 or 3 screws. Sensor replacements and pump replacements can be performed quick and easily without tools.
