SF6 Gas Dew Point Tester

Product Introduction

MOEORW-W6423D SF6 Precision Dew Point Meter incorporates an imported high-precision dew point sensor, featuring high accuracy and fast measurement speed. The instrument boasts a user-friendly display interface for intuitive reading of measurement parameters, showing not only dew point values but also micro-water, PP20, temperature, and more. Field operation is straightforward-simply connect the gas tube to the provided quick-connect fitting to begin measurement. Compact and lightweight, the moisture tester is portable and ideal for outdoor applications. Its high-capacity battery supports extended field operation.

This moisture tester is particularly suitable for measuring trace moisture in compressed air, SF6 gas in power systems, H2 gas in power plants, and various other gases.

FAQ

1)What power supply options does the MOEORW-W6423D SF6 Precision Dew Point Meter offer, and how is battery life ensured during outdoor operations?

Answer: This instrument supports two power supply methods: AC 220V power (via power adapter connection) and built-in lithium battery power. For outdoor operations, the lithium battery can be used directly, providing over 8 hours of operation to meet extended fieldwork requirements. To further extend usage time, the power adapter can be carried to connect to a nearby 220V AC power source. Additionally, the power adapter charges the lithium battery while connected to AC power.

2)What material requirements apply to the connecting tubing when using the MOEORW-W6423D SF6 Precision Dew Point Meter?

Answer: For measurements, use polished stainless steel tubing or polytetrafluoroethylene (PTFE) tubing. Polished stainless steel tubing is strongly recommended for low dew point measurement scenarios. The use of water-absorbing materials such as PVC or nylon tubing is strictly prohibited to prevent measurement errors caused by water absorption or condensation. Additionally, ensure the tubing temperature does not fall below the dew point temperature. Minimize tubing length and maximize the inner diameter to maintain measurement accuracy.

3)How can historical measurement data from the MOEORW-W6423D SF6 Precision Dew Point Meter be exported or saved?

Answer: Historical measurement data can be saved or exported in three ways: First, use the built-in thermal silent printer to print current data directly from the "Dew Point Measurement" or "Historical Data" interface; Second, insert a USB drive into the "Historical Data" interface. The instrument will automatically generate a "dewpoint.csv" file containing historical data and save it to the USB drive. The USB drive can be removed for backup after data saving is complete. Third, the instrument features large-capacity data storage, allowing historical data to be retained directly within the device. Historical data can be retrieved later by accessing the "Historical Data" interface.
