The K6050 range gas analyzers accurately measures the changes of one constituent in binary or pseudo-binary gas mixture, i.e. mixtures in which only one constituent changes. Examples include hydrogen, carbon dioxide, argon, helium and various halogenated hydrocarbons such as the Freons. Almost any single constituent of a gas mixture can be measured providing its thermal conductivity differs from that of the other components. Ranges from high ppm to 100% are possible depending on the gas being measured.A non-depleting maintenance free katharometer sensor measures the thermal conductivity of the gas. The sensor incorporates a highly sensitive element of low thermal capacity. Signal processing is provided by a microprocessor to give a level of accuracy and a range not normally associated with this type of sensor. Little or no calibration is required because of the system’s inherent high stability.A built-in sample pump means that samples can be drawn from low-pressure sources or can be naturally aspirated. An integral needle valve and flow indicator are used to control the sample flow through the analyzer.
Dual-gas measurement is provided by the KG6050. It combines the measurement abilities of the K6050 with oxygen measurement by electrochemical cell. Concentration ranges from 100ppm to 100% of oxygen are available, depending on the application.
True portability is achieved from sealed rechargeable batteries, which offer 6 hours continuous operation. Extended operation is possible by running the unit with the battery charger connected. The whole instrument is housed in a tough co-polymer waterproof case with carrying handle.
A large, alphanumeric LCD shows measured values and also displays messages and prompts for the menu driven configuration and calibration routines. These procedures are simple and straightforward.
