Related principles of high temperature flue gas moisture meter

The Smoke Moisture Velocity Detector (hereinafter referred to as the detector) is a moisture detection instrument that uses the moisture-sensitive capacitance method to measure the moisture content in the smoke gas. The instrument uses imported sensors and comes with temperature and pressure compensation correction. With the advantages of high measurement accuracy, corrosion resistance and wide operating temperature range, it is widely used in flue gas moisture measurement of boilers, furnaces and various flue gas ducts. jeiTextile Testing Instruments, Testing Equipment Manufacturer
