GDSF-311WP SF6 Gas Dew Point and Purity Tester
GDSF-311WP is ideal instrument when it is necessary to test water content and purity of SF6 gas. The core component is DRYCAP series sensors produced by Finland Vaisala company used to test dew point content and Infrared sensor produced by European company is used to test SF6 gas purity. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of gas comprehensive test instrument.
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
- Full import high accuracy sensors with auto self-calibration function to ensure the stability and reliability of dew point and purity detection data throughout the year. .
- The whole channel polymer material design, ensures no water wall hanging phenomenon and guarantees the test speed.
- The oil-free stainless steel body regulating valve is used to ensure the accuracy of the measured value.
- Use oil -free stainless steel control valve to ensure the accuracy of the test values.
- Advanced software algorithms improve the test accuracy of sensors.
- 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.
- Start up test, no need to preheat and oscillate.
- Temperature conversion and pressure data correction.
- Fuzzy computing technology.
- 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.
- Anti-electromagnetic interference circuit design to ensure product reliability.
- It can expand USB communication, serial communication, wireless communication module, and realize the communication and printing functions of the upper computer.(optional)
- Large-capacity memory, which can realize 1000 sets of data storage functions.
- Gas pretreatment function can purify the test pipeline before field test, which shortens the test time.(optional)
- The instrument has the function of testing gas recovery, which can recover the SF6 measurement gas.to protect the natural environment. (optional)
- The test data is stable and can provide both standard dew point values and converted dew point values at 20ºC.
- The best test flow area shows that the user can adjust the gas flow intuitively and quickly. Reduce test time.
- 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.
