An Embedded micro controller – based precision instrument to help ensuring optimum operation of drying equipment. Ideal for precise Monitoring of moisture or Dew point analyzer used for compressed air or nitrogen gas output from dryers systems or in process. Continuous monitoring of dew point analyzer result in reduced maintains cost and downtime caused by separated moisture. The main cause of corrosion in pneumatic system. The dew point analyzer uses a highly accurate Capacities Integrated Thin Film Water vapour sensor and is an economic alternative to the chilled-mirror dew point analyzer type Meters. Dew Point Meter analyzer utilizes embedded micro control based circuits to give a direct – read out in dew point analyzer or other units and other units corresponding to sensor output based and Psychometric equations. To achieve high accuracy it uses temperature compensation over complete operational range.
