The modular constructed ADOS KM 2000 CnHm EM equipment incorporates a microcontroller-aided measurement device for measuring solvents. All combustible gaseous CnHm compounds can be measured with the exception of chlorinated and sulphur-sublimed hydrocarbons. The thermocouples used for measurements, in conjunction with applying the principle of heat reaction, offer the following advantages: High degree of sensitivity Good accuracy Negligible drift of zero point Over-range signals have no effect Fields of Application Supervision of industrial processes KM 2000 CnHm EM: Measuring the emission of hydrocarbons, according to the German clean-air regulations KM 2000 CnHm: Measuring solvent saturation Measuring the concentration of solvents Concerning room air (ventilation) monitoring A warning is issued at very low concentrations of poisonous gas thus preventing any danger to health. Gas measurement system The sampled gas is drawn in by a pump through a feed pipe (heated if required), to the reaction chamber, via a compensating filter, flow regulator and flow-through meter. The gas is warmed to a constant temperature by means of the heater coil and jacket and finally burned in a solid-matter catalytic converter. The difference in temperature before and after combustion, is used as the measurement signal that is prepared and evaluated by the microcontroller-aided analyser.
