FAQ's
The C190H is a dedicated air permeability tester with a three-cell design for high-throughput Gurley testing. The C910H is an integrated system that measures air permeability, puncture strength, and thickness in a single automated pass – ideal when all three separator parameters need to be validated together.
Choose the C190H when your QC workflow focuses exclusively on air permeability and throughput is a priority – it tests three specimens simultaneously, reducing total test time to under 1 minute.
Choose the C910H when you need a complete separator characterisation – Gurley permeability, mechanical integrity (puncture), and dimensional uniformity (thickness) – in one instrument, saving floor space and operator time.
Yes. The C910H integrates all three measurements in one automated sequence on a single separator strip, eliminating the need for three separate instruments and multiple sample preparations.
Yes. Both instruments are specifically designed for battery separator testing. The C910H supports roll-to-roll QC workflows with its automatic sample feeding and strip sample format (up to 10 cm × 100 cm).
Yes. It also covers breathable films, related polymer products, and – with customisation – cigarette paper and other papers.
Both cover 30–1500 s/100 mL and 0.1–4 µm/(Pa·s), covering the full range of commercial battery separator grades.
Both instruments deliver pressure accuracy better than 0.01 kPa, ensuring consistent and repeatable results across test runs.
Puncture strength range: 0.1–50 N (resolution 0.001 N, accuracy ±0.5%). Thickness range: 0–2 mm (resolution 0.1 µm, repeatability 0.5 µm).
Yes. Both instruments require a user-supplied dry air source. The C910H operates at 0.5–0.7 MPa (72.5–101.5 PSI); the C190H at 600 kPa (87 PSI). An optional air compressor is available for both.
