The Product Description:
The DT-ACG-200 Precision Dew Point Meter features an open-design architecture, with a modular sensor that can be installed in the sample gas line or placed in the environment requiring detection. The principle involves projecting an LED light source onto a mirror surface, where the reflected light is measured by a photodetector. By analyzing changes in the measured light intensity, the instrument detects the presence of dew. Additionally, a control circuit maintains the mirror surface temperature at the dew point threshold, while a platinum resistance thermometer on the mirror measures the cooling surface temperature and transmits the data to the display panel.
This device features high accuracy, a wide measurement range, excellent stability, and no drift, making it widely applicable in fields such as temperature and humidity measurement work for metrology units.
