The Riken Keiki GD-F3-AA is a detector head with direct connect sensor for use in Oxygen monitoring applications.
It features a range of 0-25% volume and has options for 0-50% volume.
The GD-F3-AA is designed to connect to the RM-5000 or RM-6000 monitor panels, it has a compact & light weight design, splash-proof construction as well as being intrinsically safe with a Zener barrier.
Long life & reliable.
Low drift, accurate & long service life.
Flexible for single & multipoint O2 applications.
Allows for competitive multipoint Oxygen monitoring system construction.
The GD-F3-AA provides a rugged cost effective solution to multi-point Oxygen Deficiency systems. The GD-F3-AA connects directly to the RM-5000 monitor panel, to provide reliable measurements of Oxygen levels, in a multitude of large area applications.
It has a wide operating temperature range as low as 10 degrees celcius up to 40 degrees celcius.
Proven Sensor Technology:
The Riken Keiki GD-F3-AA is based around Rikens tried and tested OS-B11 sensor. This sensor has been used in fixed systems worldwide, and has proven to be durable and reliable.
The OS-B11 is based around Galvanic Technology.
The Riken Keiki RM-5000 is a multi-channel Gas Monitor Panel. The RM-5000 is ideal for monitoring Combustible Gases, Toxic Gases as well as Oxygen. It is ideal for multi point Oxygen monitoring systems in a range of sectors.
The RM-5000’s clever modular design allows for monitoring of 2 to 12 channels. The RM-5000 achieves this by simply by inserting indicator units to match the gas required.
A custom panel will accommodate up to 32 Channels, the modular indicator units’ slot into the case.
Users connect detector heads to detect gases such as Carbon Monoxide, Oxygen, Combustible gases, and Other Toxic Gases.
Detector heads that can be used include the SD-1, GD-A80, GD-F3-AA and GD-70D Intelligent pumped gas monitors.
The indicator units each have an independent digital display that is easy to read, each indicator has a bar meter and multi-colour display for ease of monitoring.
Power consumption is extremely low.
The RM-5000 is compatible with previous generation Riken Monitor Panels.
The RM-6000 is available for single channel applications.
The GD-F4-AA is available for sample draw applications.
