Product Introduction

This instrument using the original imported high-precision dew point sensor and the latest digital circuit control technology High-precision intelligent instrument for measuring trace moisture content in SF6 gases.

The instrument adopts intelligent self-calibration technology, wide measurement range, fast response speed, high accuracy, good linearity, and dynamic display of measurement curve.

This instrument is suitable for test the dew point values of SF6 gases, especially for air, nitrogen, inert gases and any dew point values that do not contain corrosive gases Used in electric power, petrochemical, metallurgy, environmental protection, scientific research institutes and other departments, with a very high cost performance. Measure the water content of SF6 gas and identify its arc extinguishing performance.

Product nickname：intelligent micro water meter, micro water meter, micro quality meter.

Product Characteristics

1、High stability: Under severe interference conditions, the measured data can be stable High stability: Under severe interference conditions, the measured data can be stable
2、High precision: Using imported high-performance dew point sensor and high-speed 12-bit Σ-ΔAD analog-to-digital converter, the highest resolution reaches 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: 4.3-inch true color touch LCD display, directly displaying dew point value (℃), micro-water value (ppm), date and time, and dynamically displaying dew point measurement curve. Save measurement data in real time, and can store up to 999 sets of measurement data
7、Data export: With USB transfer function, the historical data in the instrument can be directly transferred to the USB disk. Through the matching host computer software, the data can be imported, exported, printed, and other operations can be performed on the PC
8、Data printing: The instrument comes with a micro printer, which can directly print out the current test results or historical record data
9、Easy to use: Adopting original imported self-locking connectors, easy to plug and unplug, safe and reliable, without air leakage. Sensitive touch sensitive buttons facilitate operation and improve work efficiency. Built in large capacity rechargeable lithium battery, small size, light weight, easy to carry
