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.
