: Functional principle of the flue gas moisture meter

The portable flue gas moisture meter features portable design, compact structure, small size and easy to carry. Friendly man-machine dialogue menu, intuitive operation. The imported resistance-capacitance sensor features fast response and high measurement accuracy. w2dTextile Testing Instruments, Testing Equipment Manufacturer


Built-in large capacity rechargeable lithium battery, convenient to use in non-AC environment. When using an external power supply, the lithium battery can be charged at the same time. It can be used continuously for more than 168 hours after one charge. 10,000 pieces of historical data storage function, the storage period can be set freely. w2dTextile Testing Instruments, Testing Equipment Manufacturer


With the historical data export feature, the exported file format is a .TXT text file. Built-in 0.5 micron PTFE filter can effectively protect the sensor. In order to effectively prevent the acid gas dIf the sensor corrodes, a heat tracing probe can be provided. w2dTextile Testing Instruments, Testing Equipment Manufacturer
