DUAL GAS LEAK DETECTOR HX-490S Dual Gas is the most advanced sniffing Helium/Hydrogen leak detector designed specifically for industrial environments. The HX-490S Dual Gas utilizes industrial-grade mass spectrometer to achieve the highest sensitivity, fastest response-time, and smallest footprint. With a touch of a button, this dual gas unit can detect either Helium or Hydrogen tracer gases, while using a single built-in dual purpose calibrated gas leak. Fastest response time in the industry (less than 0.5 seconds) Tracer gas background suppression Sensitivity to 5 x 10-8 atm cc/sec Less than 3 minutes total start-up time Fully automatic calibration sequence with built-in dual purpose gas leak User selectable between helium and hydrogen sniffer Front panel key lock-out Sealed membrane keypad Fully interactive system diagnostics with multilingual displays High output (110dB) adjustable audio alarm Flow units (cc/sec, oz/yr, Pa m3/s) Helium or hydrogen sniffing test

Exhaled Breath = 78.04% Nitrogen + 13.6%-16% Oxygen = CO2 Car Exhaust = Carbon Dioxide + Carbon Monoxide + Sulphur Dioxide + Nitrogen Oxides + Hydrocarbons How do we know this? Gas detection in Continuous Emission Systems (CEMS), combustion analysers and environmental monitoring are key to ensuring that the world we live in is monitored for its pollution and environments we work in are safe to do so as gases can be detrimental to life. Knight Optical provide a number of optical components that are used in Gas Detection Systems. We can also provide interference bandpass filters that work within the IR, front surface mirrors, gas cells and singlet lenses and window made from Germanium (Ge), Calcium Fluoride (CaF2), Silicon (Si), Quartz/ Fused Silica, Magnesium Fluoride (MgF2) and Sapphire (Al2O3).

With the development of CHARM®, Open Grid Europe is providing an efficient leakage control method for natural gas pipeline networks and thus an alternative to the labour intensive practice of conducting on-site inspections of the pipelines with gas detection devices. CHARM® is a highly accurate infrared laser system integrated in a helicopter that is capable of precisely detecting even very low methane concentrations from the air. Even in the case of very complex pipeline topologies, the course of the pipeline can be detected consistently on a large scale during the flight by an automatic, highly precise scanning beam control system (autotracking), thus ensuring a reliable leak tightness inspection of the natural gas pipeline.
