K6050 and KG6050 Series portable gas analysers Features N Wide range of gases monitored, including hydrogen, carbon dioxide, argon and SF6 N Optional oxygen measurement N Rugged and portable N Fast warm-up with rapid response time N Weatherproof to IP67 Hitech K6050 Series analysers A built-in sample pump means A large, alphanumeric LCD shows accurately measure the changes of that samples can be drawn from measured values and also displays one constituent in binary or pseudo- messages and prompts for the menu- binary gas mixtures (ie, mixtures in naturally aspirated. An integral needle driven configuration and calibration which only one constituent changes). valve and flow indicator are used to routines. These procedures are simple Examples include hydrogen, carbon control the sample flow through the dioxide, argon, helium and various halogenated hydrocarbons such as the Freons. Almost any single constituent of providing its thermal conductivity differs combines the measurement abilities of from that of the other components. The the K6050 with oxygen measurement ranges provided depend upon the gas by electrochemical cell. Concentration being measured but can be from high oxygen are available, depending on Applications N Hydrogenation processes N Gas purity sensor measures the thermal conductivity True portability is achieved from sealed rechargeable batteries, which highly sensitive element of low thermal offer 6 hours continuous operation. capacity, which requires no mainte- Extended operation is possible by nance.
