The TOPGSM-I+ precision dew point meter from the Tuopu brand is an ideal choice for industrial environments with low dew points and the need to control dry points. It has a chemical substance removal option, which enables accurate and stable measurements in environments with high concentrations of chemical substances and cleaning agents, thus ensuring accurate measurements between each calibration interval. This function can be executed online through the control system or periodically at preset time intervals.
