	Thermal Conductivity Hydrogen & Chlorine Gas Analyzer (Wall Mount) - KK650 Hitech Instruments has the experience of 30 years designing and manufacturing gas analysers. Now embedded in the new, state of the art, purpose built factory of parent company. Very simple to use and service Benign surrogate gas calibration Virtually indestructible and interchangeable sensors Low cost of ownership Comprehensive set of programmable alarm relay and analogue outputs View Full Specification The KK650 thermal conductivity hydrogen & chlorine gas analyzer is designed to meet all the challenges of measuring chlorine and hydrogen in the presence of nitrogen and oxygen (so called inerts) in chlorine production plants. It uses a chemically inert maintenance free thermal conductivity sensor (katharometer), equipped with two measurement chambers, combined with microprocessor based signal processing to provide highly reliable and accurate process monitoring. Fixed chlorine gas detector Chlorine monitor Chlorine gas detection Chlorine gas for semiconductor Chlorine gas exposure limits Chlorine gas dangers Chlorine gas All types of chlorine plant can be monitored by one of two models which differ in the hydrogen range and resolution (see specification). Each provides accurate monitoring of the process gas from start up to normal running. How it Works Firstly, the thermal conductivity of the plant sample is measured. Next, the sample is passed through a heated reactor tube where the hydrogen gas reacts with some of the chlorine. A second sensor then measures the thermal conductivity of the reacted mix. The difference in thermal conductivity between the first and second measurement is used to calculate the hydrogen concentration. The chlorine concentration is calculated from the first thermal conductivity measurement by taking into account the effect of hydrogen. Advantages Virtually indestructible sensor with indefinite life Extremely easy to clean should sample train become contaminated Sensor interchangeability for minimum down time Highly stable sensor that is unaffected by fluctuations in sample and atmospheric pressures Long calibration intervals using benign surrogate gasses Calibration of chlorine analyzers normally requires the handling of hazardous gases by highly trained personnel. Sometimes this necessitates removing the analyzer or sensor from the plant and performing the tests in a laboratory. The KK650, as well as being able to be calibrated on chlorine and chlorine/hydrogen mixtures, can be calibrated by two other methods that overcome the problem of handing hazardous gases. Firstly, it can be calibrated on benign easily obtained surrogate gases, argon for chlorine span and hydrogen in air for hydrogen span. Alternatively, the process gas can be used if there is sufficient confidence in its analysis provided by other analyzers (e.g. gas chromatographs). It can also be calibrated using a combination of these methods.
