Product Introduction

The HF-WC-624 SF6 Gas Mixture Analyzer provides a convenient on-site detection method for SF6 mixed gas. When in use, it connects to the air chamber of pressurized SF6-filled electrical equipment. SF6 gas flows through the electrochemical sensor at a fixed flow rate, and the instrument directly measures the purity of SF6 gas.

Main Applications: SF6 gas mixture testing, routine inspection, partial discharge monitoring, gas purification & filtration monitoring, and high-voltage fault contact inspection.

Features & Main Functions

Adopts anti-crosstalk interference technology, featuring high accuracy and excellent repeatability.
Equipped with dynamic ambient temperature compensation function.
Built-in imported electronic mass flowmeter for precise gas flow control.
Automatically calculates average values after multiple measurements to reduce testing errors.
Internal air purge function effectively prolongs the service life of the instrument.
Powered by rechargeable battery, compatible with both AC and DC power supplies.
Graphical operation interface for easy and intuitive operation.

FAQ | SF6 Gas Composition Analyzer

Q1: What gas components can this SF6 analyzer test?

A: It can detect volume concentration of SF6, oxygen (O₂) and nitrogen (N₂). The measuring range of SF6 is 0~100%, and customized ranges are acceptable according to customer demands.

Q2: What is the testing accuracy and resolution?

A: Accuracy: SF6 ±0.5%, O₂ ±1%, N₂ ±1%; Resolution reaches ±0.01%, which can meet the precision requirements for daily SF6 gas inspection in substations.

Q3: How does the instrument guarantee stable measurement results?

A: It adopts anti-crosstalk interference technology and dynamic temperature compensation function. Multiple measurements will be averaged automatically to reduce test errors effectively.

Q4: What is the maximum working air pressure it can bear?

A: Rated working pressure is ≤1.0MPa, perfectly suitable for on-site sampling and detection of GIS, circuit breakers and other SF6 high-voltage equipment.

Q5: How is the gas flow controlled during testing?

A: Equipped with imported electronic mass flowmeter, the flow can be adjusted between 0~0.9L/min steadily to ensure consistent sampling speed.

Q6: How many historical data records can be stored?

A: It can save up to 100 groups of test data. Matched supporting software supports data exporting and printing for filing and review.

Q7: Is the device portable for outdoor field work?

A: Yes. It weighs only 2.8kg with compact size (340×230×130mm). Built-in large-capacity lithium battery supports over 8 hours continuous offline operation.

Q8: Can the instrument work under harsh ambient conditions?

A: Operating temperature range: -30℃ ~ 50℃, applicable humidity ≤90%RH; it adapts to cold northern areas and high-temperature outdoor substation environments.

Q9: What is the function of internal air purge?

A: The built-in air cleaning function cleans residual gas inside the pipeline after each test, avoiding cross-contamination between different samples and extending the service life of sensors.

Q10: What accessories are included in the standard delivery package?

A: 5m sampling tube, power adapter, spare pipe fittings, bilingual operation manual, factory calibration certificate, printing software CD and shockproof portable case are all equipped.

Q11: Does it support both AC and DC power supply modes?

A: Dual AC/DC power supply design. You can use the built-in lithium battery outdoors, or plug in AC power for long-time indoor continuous measurement.

Q12: What are the main application scenarios of this tester?

A: Widely used for SF6 gas mixture detection, routine equipment inspection, partial discharge monitoring, gas purification monitoring and high-voltage fault contact checking in power substations.
