Description
Overview
The GAO Tek portable dew point meter uses a capacitive sensor. Its working principle is to measure the trace moisture content in the gas based on the change in capacitance value caused by the concentration of water molecules. It uses high-performance alumina and polymer film sensors, and advanced digital processing technology to achieve continuous and rapid online trace moisture analysis.
Features
- 128*64 LCD
- High-performance sensor, long life, high sensitivity, and fast response speed.
- Built-in large-capacity long-life lithium battery, battery power display, automatic voltage protection, can be used continuously for more than 8 hours on a single charge
- Data backup and data recovery functions
- Built-in precision air pump (optional)
Applications
- Air separation, petroleum, chemical industry.
- Semiconductor manufacturing, drying industry, food industry, pharmaceutical industry, machinery manufacturing.
- Analysis and detection of trace moisture content in various gases in electric power and other industries.
