4-in-1 SF6 Decomposition Gas Analyzer

MOEORW-WQZ41 SF6 decomposition product detector is a modular multi-component gas testing instrument, upgraded with HF gas detection channel compared with conventional three-gas detectors. The equipment adopts electrochemical sensor array with four core anti-interference technologies: cross-interception filtration, pump-driven residual gas evacuation, real-time dynamic temperature correction and carrier gas error compensation. Operators complete pipeline connection, power-on self-test and flow adjustment to acquire synchronous concentration values of SO₂, H₂S, CO and HF in SF6 insulating gas. All test data is stored on local memory, supporting USB batch export and on-site printout for power equipment fault diagnosis.

Operating ambient limits: Operating temperature -20℃ ~ 50℃, relative humidity 15%~90%, atmospheric pressure 70~106kPa, input power AC 180V~240V 50/60Hz. Storage & transit limits: Storage temperature -30℃ ~ 55℃, relative humidity ≤95%, atmospheric pressure 70~106kPa; storage space must exclude corrosive volatile substances.

Core Detection Parameters

Physical Dimension & Weight

Hardware & Technical Design Layer
1.Four-channel independent electrochemical sensor layout, adding dedicated HF detection module for full-spectrum SF6 decomposition gas monitoring.
2.Dual-channel temperature acquisition module to synchronously collect sample gas and ambient temperature, matching sensor temperature characteristic curve for dynamic drift correction.
3.Multi-stage chemical filter assembly to block interfering volatile gas and eliminate cross-response of four mixed gas sensors simultaneously.
4.Differential pressure pump purging system: filtered dry air circulates inside gas chamber to completely eliminate residual test gas and avoid cross-test contamination.
5.Lightweight integrated cabinet with touch screen operation, built-in thermal printing module and USB external storage port for field data output.

Performance Index Layer
1.Synchronous four-gas real-time measurement with unified 0.1 µL/L high resolution and ≤60 s rapid sensor response.
2.Optimized low-concentration accuracy and repeatability indicators compared with three-gas models, improving detection precision under trace decomposition gas conditions.
3.Dual-mode zero calibration supporting pure SF6 carrier gas or ambient air calibration for flexible field operation.
4.Automatic 5-minute power-on self-calibration to reduce manual debugging workload for on-site operators.

Practical Application Value Layer
1.Intelligent gas purging mechanism to reduce sensor corrosion risk under high-concentration decomposition gas and extend sensor service cycle.
2.Complete data management suite: real-time data storage, single record printing, historical data browsing, single record deletion and full memory formatting.
3.USB automatic CSV file generation for batch data export to PC for long-term equipment operation trend analysis.
4.Multi-mode zero calibration function to correct sensor zero drift after incomplete gas chamber purging without extra auxiliary equipment.

The four-component detector realizes full coverage of SF6 typical decomposition gas detection, suitable for the following industrial scenarios:
1.Power grid operation & maintenance: Fault diagnosis, periodic preventive test of GIS, SF6 circuit breakers, transformers and other high-voltage insulated equipment.
2.Gas manufacturing industry: Purity inspection of finished SF6 products and monitoring of gas storage & transportation containers.
3.National defense, metallurgy and steel manufacturing: SF6 process gas pipeline monitoring and internal insulation detection of industrial sealed equipment.

Routine Maintenance

1.Lithium Battery Maintenance

• Connect matched power adapter for charging when battery power is exhausted; charge for minimum 1 hour before normal operation after deep discharge.
• Keep lithium battery fully charged during long-term idle storage to slow down battery capacity attenuation.

2. Equipment Storage Rules

• Store in dry, corrosion-free indoor environment; adjust flow valve to closed state gently, forbidden over-tightening to prevent valve core damage.

3.Surface & Pipeline Maintenance

• Clean touch screen and outer casing with mild neutral detergent; disconnect power supply before all maintenance work to prevent electric shock and circuit short circuit.
• Periodically purge internal and external gas pipelines with pure nitrogen to remove accumulated dust and residual pollutants affecting measurement precision.

Calibration Cycle & After-Sales

Annual professional calibration is required to maintain specified detection accuracy; users can send the unit back to the manufacturer for paid calibration service after warranty expiration.

Non-artificial equipment faults within warranty period enjoy free repair service; man-made damage and out-of-warranty faults are handled with paid maintenance solutions
