The Edgetech Instruments Model DewTrakII MO dew point/humidity transmitter is an optical chill mirror hygrometer designed to continuously measure the moisture content and Barometric pressure in the motor octane testing process. It is used to monitor and ensure compliance with test standards ASTM D2700, D2699, D2885. It guarantees measurement compliance for allowable Humidity range between 25–50 gr/lb & Pressure 21–30 in Hg (0.1 in Hg).
The DewTrak MO powered by 24Vdc and can be easily fitted to existing Knock engine systems. It is specifically designed to measure conditions required for Motor Octane (MON),& Research Octane (RON) It uses the chilled mirror dew point temperature condensation principle to determine the water vapor concentration and barometric pressure measurement of the motor intake air fuel mix.
The unit comes with a two stage chill mirror sensor (insertion probe style, 60°C depression), , barometric sensor, 24Vdc input power supply, a manifold adapter kit, two selectable analog outputs, RS232 (bi-directional), two programmable alarm relays, LCD display, reads in grains/lb, barometric pressure & dew point, instruction manual & one year warranty.
