GfG Instrumentation, 4021-DPX, RAM 4021-DPX CO and Dew Point Monitor for Medical Breathing Air Applications
This unit is designed to provide continuous monitoring of CO and dew point levels in breathing air. The instrument's electronics are enclosed in a NEMA-4X polycarbonate case. The case is corrosion resistant, positively pressurized by the compressor supply line, and sealed except for a bleed hole (to release the compressor's air). The unit operates on 110 VAC power. It comes equipped with a case-mounted horn that can be disconnected if it is not required.
Plug the unit into a 110 VAC outlet and the display will show introductory messages and a warm-up countdown. If the unit does not power up, check the electrical connections and try re-plugging in the unit. If start-up does not occur, call the factory.
Although the unit is calibrated at the factory, it may require CO recalibration due to handling. The only way to ensure that the sensor is operating properly is to test it with calibration gas.
