Overview

Adopting constant-temperature thermal insulation design, this analyzer minimizes disturbances from sample gas temperature and ambient humidity to deliver enhanced measuring accuracy. It mainly tests the volume and mass percentage purity of SF6 mixed with air or nitrogen. It can also measure purity of other mixed gases such as hydrogen and nitrogen, provided you inform us of the gas composition before purchase. Widely deployed in power, chemical, metallurgical, steel and specialty gas industries for gas purity detection.

FAQ – SF6 Gas Purity Analyzer

Q1: What is the main function of this SF6 Gas Purity Analyzer?

A: It accurately measures the volume percentage purity of SF6 gas mixed with air or nitrogen inside high-voltage electrical equipment. It can also test other mixed gases such as H2 and N2 for industrial use.

Q2: Why is constant temperature insulation design adopted?

A: This design effectively reduces the influence of sample gas temperature and ambient humidity, greatly improving measurement stability and accuracy.

Q3: What is the measuring range and resolution?

A: The purity measuring range is 0~100%, with high resolution up to 0.01% and indication error within ±0.5%.

Q4: How fast is the test response?

A: The response time is less than 60 seconds, which enables quick on-site gas inspection work.

Q5: What is the applicable sample gas pressure and flow?

A: The allowable sample gas pressure is ≤10 bar; the standard flow rate is 0.2L/min (tolerance ±30%).

Q6: Can the instrument work under harsh ambient conditions?

A: Yes. It works normally at -20℃ ~ +50℃ ambient temperature and 5%~95% RH humidity range.

Q7: How is the instrument powered?

A: It supports built-in lithium battery for field mobile measurement, as well as 100~240V AC universal mains power, dual power supply available.

Q8: What advantages does the built-in valve and flowmeter bring?

A: The internal pressure stabilizing valve and electronic flowmeter keep stable gas intake, avoiding unstable data caused by fluctuating air pressure.

Q9: Is the operation complicated for field workers?

A: No. Equipped with color touch screen and graphical interface, the operation is intuitive and easy to master without complex training.

Q10: How long is the service life of the detection sensor?

A: The detector module is long-lived, with stable performance and low later maintenance cost for long-term repeated testing.

Q11: Do you offer after-sales warranty?

A: We provide one-year global warranty and permanent professional technical guidance for all our testing instruments.
