HYGROMETER MEETS ASTM STANDARD FOR KNOCK ENGINE
Featured Product from Edgetech Instruments Inc.
Edgetech Instruments Model DewTrak II-MO chilled mirror hygrometer provides dew/frost point, temperature, and barometric pressure analysis for Motor Octane testing in CFR engines, as per ASTM procedures D2699, D2700 and D2885. It guarantees measurement compliance for the allowable humidity range between 25 and 50 gr/lb. and the pressure range between 21 and 30 in Hg.
Easy to use and available in multiple configurations, the DewTrak II-MO provides precision measurement, long life and low maintenance.
The DewTrak II-MO is powered by 24 Vdc and can be easily fitted to existing knock engine systems. It is specifically designed to measure conditions required for Motor Octane Number (MON), and Research Octane Number (RON). It uses the primary method chilled mirror dew/frost point temperature condensation principle to determine the water vapor concentration and a barometric pressure sensor, for motor intake air/fuel mix. Outputs include 4 to 20 mA, 0 to 5 Vdc, or 0-10 Vdc and an RS232 serial port as well as electrically isolated relay contacts.
