The DT-ACG200G Chilled Mirror Precision Dew Point Meter adopts an open design, and the split sensor can be installed in the sampling gas path or placed in the environment to be detected. The principle is that the LED light source emits light onto the mirror surface, the light reflected by the mirror surface is measured by the photoelectric sensor, and the occurrence of dew can be detected by using the change in light intensity measured by the photoelectric sensor; the control circuit controls the mirror surface temperature at the critical point of the dew condensation temperature, and the platinum resistance thermometer in the mirror surface transmits the measured cooling surface temperature data to the panel for display. This equipment has high precision, wide range, good stability and no drift, and is widely used in temperature and humidity metering work in metering units and other fields.
