Portable GDP-311PCAW SF6 Gas All in One Quality Analyzer

Product Description

Portable GDP-311PCAW SF6 Gas All in One Quality Analyzer

General information

GDP-311PCAW SF₆ gas quality analyzer is a portable device designed to measure SF₆ gas purity, dew point, composition, CF4 content and air content. The core component with NDIR sensor produced by European sensor company to test SF₆ gas purity, RC sensor produced by Vaisala, Finland to test dew point, NDIR sensor produced by Smartgas, Germany to test SF₆ gas decomposition product--CF4. the air sensor adopts itg technology. Besides, we also adopt professional hardware chips and excellent software algorithms of STMicroelectronics.

Application

SF6 analysis fo power system
SF6 gas cylinder gas quality test
Quality test of SF6 gas for recovery and reuse
High purity gas manufacturing
Semiconductor industry dry gas supply
Research and development use

Features

With imported high-precision sensor and self-calibration function, test results are more accurate all year round.
With polymer material design throughout gas pipeline from Legris, Camozzi and Swagelok, ensure no wall-clinging condition,and fast test speed.
Oil-free stainless steel regulating valve is adopted to ensure test accuracy.
Advanced software algorithm improves the test accuracy of imported sensors.
With flexible case configuration. User can assemble spare parts more easily.
Power on to detect, no need for oscillation.
Temperature conversion and pressure data correction.
Fuzzy computing technology.
High-power lithium power supply system can realize AC DC double power supply. No need for on-site AC power supply. Lithium battery can work continuously for more than 8 hours alone.
Anti-electromagnetic interference circuit design, to ensure the reliability of products.
USB communication, serial communication and wireless communication modules can be extended to realize PC communication and printing functions. (optional)
Mass storage, which can realize the storage function of 1000 groups of data.
Gas path pretreatment function can purify the test pipeline before the field test work, which shortens the test time. (optional)
With environment protection function. The instrument has a test gas recovery function, which can recycle the measured sulfur hexafluoride gas. (optional)
The purity measurement accuracy is 0.5% in the full range, which can be applied to measure high concentration SF₆ gas and 70% SF6 gas.
The display of the best test flow area is clear and intuitive. Users can adjust the gas flow directly and quickly.
The air inlet adopts the design of miniature self-sealing joint, so the measured air path will not leak when it is broken.
