Product Introduction

his 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 the condition of serious interference, the measured data can be stable at ±In the within of 0.5℃, it has excellent long-term stability and good repeatability
2、High precision: adopt imported high-performance dew point sensor and high-speed 12 Σ - Δ AD AD converter, the highest resolution is 0.1 ℃, fully meet the requirements of actual measurement. Within the full range, the measurement results are accurate and reliable, the measurement range is wide, the response speed is fast, and the measurement results are stable and reliable
3、Intelligent: start up self-calibration, sensor probe can automatically calibrate zero, automatically eliminate the system error caused by zero drift, ensure the accuracy of measurement
4、Multiple protection: with oil filter, free from dust particles and most chemical pollution, it can protect the sensor against oil pollution, and is suitable for industrial environment
5、Rapid gas saving: after entering the measuring state, the determination time of dew point value is 3 ~ 5min
6、Powerful functions: 4.7 "genuine color liquid crystal display, Chinese interface.It directly displays the dew point value (℃), moisture content value (uL/L), date and time, and dynamically displays the dew point measurement curve.Real-time storage of measurement data, up to 100 sets of measurement data can be stored
7、Communication function: RS232 interface can be connected with PC serial port, which is convenient for PC to further process data
8、Easy to use: imported from Japan, self-lock joint, convenient plug and pull, safe and reliable, no leakage.Sensitive touch The keys easy to operate, improve work efficiency.Built-in rechargeable lithium battery, small volume, The weight of The light, easy to carry
