Product Description

General Information

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. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of gas moisture test instrument.
 

Application

• Analysis of trace moisture, purity and decomposition products of SF6 gas electrical equipment for electric power
• SF6 gas cylinder gas quality test
• Recycling of SF6 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. Fully imported high-precision sensor with self-checking function to ensure the moisture, purity and decomposition product detection data is stable and reliable throughout the year.
2. Full-channel polymer material design, the device uses Legris, Kangmaosheng, Swagelok products to ensure no wall hanging phenomenon and ensure test speed.
3. The oil-free stainless steel body regulating valve ensures the accuracy of the detected value.
4. Advanced software algorithms improve the test accuracy of imported 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. Start up and test without shaking.
7. Temperature conversion and pressure data correction.
8. Fuzzy computing technology.
9. High-power lithium battery power system can realize dual AC and DC power supply. No on-site AC power is required. Lithium battery power supply continues to work for more than 8 hours without the need for an external power supply.
10. Anti-electromagnetic interference circuit design to ensure product reliability.
11. It can expand USB communication, serial communication, wireless communication module, and realize the communication and printing functions of the host computer. (optional)
12. Large-capacity memory for 1000 sets of data storage.
13. The gas path pretreatment function can be used to purify the test pipeline before the field test work, which shortens the test time. (optional)
14. The instrument has a test gas recovery function to recover the sulfur hexafluoride measurement gas. Protect the natural environment. (optional)
15. The test data is stable and can provide both standard dew point values and converted dew point values at 20 °C.
16. Purity measurement is 0.5% measurement accuracy of full scale. It can be used for high concentration SF6 gas measurement or 70% SF6 gas measurement.
17. The best test flow area shows that the user can adjust the gas flow intuitively and quickly. Reduce test time.
18. 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.
