The Model 203 Series Portable Dew Point Analyzers have been designed primarily for accurate dew point measurement of dry non-corrosive industrial gases, or dry oil-free air. The aluminum oxide sensing element varies its electrical capacitance in direct proportion to variations in the sample gas dew point.

The 203 Series can have either a built-in pressure regulator for positive pressure samples, or a built-in sample pump for atmospheric pressures, or both. The sample flow is shown on a flowmeter on the front or top panel. The dew point is shown on a touchscreen display. A 4-20mA output is optionally available. Some models have rechargeable battery operation. Please contact Nova for the correct version for your application.



Models:
  • 203K - suitcase cabinet with display on inside; display visible when case is opened
  • 203KX - suitcase cabinet with display on outside; display visible when case is closed
  • 230BT - rectangular bench top style cabinet
