DWS-III  Intelligent SF6 Dew Point Analyzer

Application

This instrument is suitable for measuring the dew point value of SF6 gas. It can also measure the dew point value of air, nitrogen, inert gas and any non-corrosive gas. It is especially suitable for power, petrochemical, metallurgy, environmental protection, scientific research institutes and other departments, with extremely high cost performance.

Features:

(1) High stability: Under severe interference conditions, the measurement data can be stable within the range of ±0.5℃, and has excellent long-term stability and good repeatability.

(2) High precision: It adopts imported high-performance dew point sensor and high-speed 12-bit Σ-ΔAD analog-to-digital converter, with the highest resolution reaching 0.1℃, which fully meets the actual measurement requirements. The measurement results are accurate and reliable within the full range, with a wide measurement range, fast response speed, and stable and reliable measurement results.

(3) Intelligence: Self-calibration at power on, the sensor probe can automatically calibrate the zero point, automatically eliminate the system error introduced by zero drift, and ensure the accuracy of measurement.

(4) Multiple protection: With oil filter device, it is not affected by dust particles and most chemical pollution, and can protect the sensor from oil pollution, which is very suitable for use in industrial environments.

(5) Fast and gas-saving: After entering the measurement state, the dew point value measurement time is 3~5min.

(6) Powerful functions: 4.7-inch true color touch LCD display, full Chinese operation interface. Directly display the dew point value (℃), micro-water value (uL/L), date and time, and dynamically display the dew point measurement curve. Save the measurement data in real time, and can store up to 100 sets of measurement data.

(7) Communication function: The RS232 interface can be connected to the PC serial port, which is convenient for the PC to further process the data.

(8) Easy to use: It adopts the self-locking connector imported from Japan, which is easy to plug and unplug, safe and reliable, and has no air leakage. The sensitive touch button is easy to operate and improves work efficiency. Built-in large-capacity rechargeable lithium battery, small size, light weight, easy to carry.
