The fixed gas detector uses an advanced catalytic or electrochemical sensor that translates the gas concentration in the air into a digital signal output. The detector working with a gas controller can be used to detect gas in a refinery, chemical plant, LPG station, boiler room, painting plant, and other places where gas exists.

This analyser is ideal for challenging applications such as measuring ppm levels of oxygen in hydrogen, helium and flammable gases, as well as high levels of oxygen in concentrators, incubators and glove boxes. The high and low-range oxygen sensors switch over automatically using a hysteresis function to optimise readings, with an adjustable switching point. The optical oxygen sensors are virtually drift-free and are factory-calibrated for life, making their lifetime cost of ownership more economical. These sensors are suitable for demanding high-oxygen applications where VOCs, flammable gases, CO, H₂ or He are present in the gas sample.
The optical oxygen sensor technology is based on luminescence quenching of a sensor dye. The dye is excited with red light, and the properties of the resulting luminescence are measured in the near infrared. The presence of molecular oxygen in the gas quenches the luminescence, changing its intensity and producing a calibrated oxygen measurement. This principle is very robust, shows virtually no interference from other gases and has a very low drift. It does not deplete over time, unlike galvanic oxygen sensors with their limited shelf life, as the optics and electronics are hermetically sealed from the measured gas. For typical indoor conditions, a 5–10 year operating life is expected.
With its sensitivity of 3g/a, it enables reliable detection of the smallest refrigerant leaks. It has been developed in accordance with the strict guidelines of the F-Gas Regulation and BS EN 14624:2012. The RL 200 meets the highest standards in terms of environmental protection and technical precision. It is easy to use. The digital display gives you an overview of the measured values. The automatic zero value setting makes handling even easier, so that you can concentrate on the actual task: detecting leaks in the refrigerant system. Increase the efficiency of your maintenance processes and minimise potential environmental impacts.
