3-in-1 SF6 Gas Comprehensive Analyzer Gas Dew Point Tester

Product Description

3-in-1 SF6 Gas Comprehensive Analyzer Gas Dew Point Tester 

GDSF-311WPD is ideal instrument when it is necessary to test water content, purity and decomposition products of SF6 gas. The core component of dew point test is DRYCAP®  series sensors produced by Finland Vaisala company. The infrared principle SF6 gas purity testing sensor manufactured by European Sensor Company is used to test the purity of SF6 gas. The electrochemical sensor manufactured by Membrapor in Switzerland is used as the sensing element for the test of SF6 gas decomposition products. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of 3-in-1 gas analyzer.


Application

Moisture monitoring of SF6 gas electrical equipment for electric power
SF6 gas cylinder gas quality test
High purity gas manufacturing
Semiconductor industry dry gas supply
Research and development use
Clean room/dry house monitoring
Metal heat treatment site and laboratory industrial gas humidity detection, such as air, CO2, N2, H2, O2, SF6, He, Ar and other inert gases.

Features
 

1. Imported high-precision sensors with self-calibration function ensure the stability and reliability of moisture, purity and decomposition detection data throughout the year.
2. All gas path with high polymer material design, ensures no water wall hanging phenomenon and guarantees the test speed.
3. The oil-free stainless-steel body regulating valve is used to ensure the accuracy of the measured value.
4. Advanced software algorithms improve the test accuracy of sensors.
5. Combined chassis configuration solution, users can easily combine related instruments and accessories. The overall package is carried, which makes the user have a more relaxed experience.
6. Startup test, no need to preheat and oscillate.
7. Temperature conversion and pressure data correction.
8. Fuzzy computing technology.
9. High-power lithium battery power, realize AC and DC dual power supply. No on-site AC power is required. Lithium battery power supply continues to work for more than 8 hours without the need of an external power supply.
10. Anti-electromagnetic interference circuit design to ensure product reliability.
11. Large-capacity memory, which can realize 1000 sets of data storage functions.
12. The test data is stable and can provide both standard dew point values and converted dew point values at 20ºC.
13. Purity measurement accuracy is 0.5% in the full range. It can be applied to the measurement of high concentration SF6 gas and 70% content SF6 gas.
14. The best test flow area shows that the user can adjust the gas flow intuitively and quickly. Reduce test time.
15. The air inlet is designed with a miniature self-sealing joint, and the air path to be tested will not leak when the air path is disconnected.
