XGWL-Z SF6 Intelligent Moisture Meter

Product Introduction
The XGWL-Z SF6 Intelligent Moisture Meter is a portable gas humidity analyzer designed for fast and accurate dew point and moisture measurement. It features a wide measurement range, rapid response, short testing cycles, clear display, and simple operation.
The instrument is especially suitable for SF6 gas moisture testing in electrical power systems. It can also measure the humidity of air, nitrogen, inert gases, and other non-corrosive gases. The XGWL-Z is widely used in electric power, petrochemical, metallurgy, environmental protection, scientific research, and industrial maintenance.

Performance Features
• Fast measurement: No preheating is required after startup. The instrument quickly reaches the dew point measurement condition.
• Low gas consumption: Approximately 2 L of gas is consumed per test at 101.2 kPa.
• Reliable self-locking connector: Equipped with an original German self-locking connector to ensure safe connection and reduce gas leakage.
• Data storage: Stores up to 60 sets of measurement data.
• Clear LCD display: Displays dew point, moisture content in ppm, ambient temperature, ambient humidity, date, time, and battery status.
• Portable design: Compact and lightweight structure for convenient transportation and field testing.
• Built-in rechargeable battery: A fully charged battery supports approximately 8 hours of continuous operation.
• Automatic self-calibration: Built-in self-check and calibration function after startup.
• Chinese user interface: Full Chinese menu and backlit LCD display simplify operation in low-light environments.
• AC/DC power supply: Supports both external power and rechargeable battery operation.

Working Principle
The XGWL-Z SF6 intelligent moisture meter measures gas moisture through dew point detection technology.
During measurement, the gas sample enters the instrument through the sampling connection at a controlled flow rate. The sensor detects the moisture content of the gas and determines the corresponding dew point temperature. The instrument then processes the sensor signal and displays the dew point, moisture content, and relevant environmental parameters on the LCD screen.
The measurement result can be stored in the internal memory for later review and recordkeeping.
