IS9561

Fast, accurate, and non-destructive coating thickness testing for aluminum collapsible tubes

The IS9561 Tube Probe is Innosen’s high-precision solution for measuring internal and external lacquer thickness on aluminum collapsible tubes—without the need for destructive weigh-strip-weigh methods. The IS9561 pairs natively with the IS860 CoatPro™ Coating Thickness Gauge — a matched probe-and-gauge system that delivers exceptional repeatability and reproducibility (R&R), helping tube makers ensure product safety, performance, and cost efficiency.

With its narrowed probe tip and innovative flexure system, the IS9561 can measure tubes as small as ø12 mm and lengths up to 160 mm, delivering accurate results every time. From optimizing spray machine settings to maintaining coating integrity, this smart probe makes quality control simple, fast, and reliable. Measurements can be collected and analyzed in IS1100 Innolytix® QA analysis software.

Tube Probe IS9561

We did not follow the standard. We set it.

The probe came first. Innosen has been building enamel rating and coating thickness probes for metal packaging for decades — the standard the industry now calls by name was our doing. Probes we designed reach the market under other brand names.

So when you buy the Tube Probe IS9561, you are buying the current generation from the people who designed it, hold the drawings, machine the parts and stock the spare tips. Engineering answers, calibration guidance, spare probes and lead times come from the source rather than from a label.

COMMON QUESTIONS FROM TUBE MAKING QA TEAMS

K
L

What is the IS9561 Tube Probe?

The IS9561 Tube Probe is Innosen’s non-destructive coating thickness probe for aluminum collapsible tubes. It measures internal and external lacquer thickness in seconds, so tube makers can verify coating weight without cutting, stripping and weighing samples. It is used together with the IS860 CoatPro™ Coating Thickness Gauge.

K
L

How does the IS9561 measure lacquer inside a collapsible tube?

A slim probe tip reaches the internal lacquered surface, while a rotary flexure system lets the tip settle without stiction. A force multiplier flexure keeps contact pressure uniform on every reading, and the dead-weight design resists temperature-based variation. The reading therefore reflects the coating itself rather than the operator or the ambient conditions.

K
L

Does the IS9561 Tube Probe replace the weigh-strip-weigh method?

Yes. Weigh-strip-weigh destroys the sample, occupies a technician for a considerable time and returns only an average film weight. The IS9561 measures an intact tube at the position you choose, so QA teams can test far more frequently, react to a drifting spray machine sooner and keep the tested product.

K
L

What tube sizes does the IS9561 Tube Probe fit?

The probe measures aluminum collapsible tubes from ø12 mm upwards, with a maximum tube length of 160 mm. The unit itself is 315 mm long, 109 mm wide and 295 mm high and weighs 4.5 kg, so it sits comfortably on a QA bench beside the line.

K
L

Which gauge does the IS9561 Tube Probe work with?

The IS9561 is designed to work with the IS860 CoatPro™ Coating Thickness Gauge. The gauge supplies the measurement electronics and data handling, while the probe supplies the stable, stiction-free contact that makes those readings repeatable. Both come from Innosen, so there is a single point of support for the whole measurement chain.

K
L

Why does consistent probe pressure matter for coating thickness measurement?

Contact pressure changes the reading. When pressure varies between operators, shifts or ambient temperatures, the gauge reports coating variation that does not exist, and genuine process drift disappears into the noise. The IS9561 applies the same force on every measurement through its flexure system, which is what delivers world-class repeatability and reproducibility.

K
L

Can IS9561 measurements be analyzed and reported automatically?

Yes. Readings collected through the IS860 CoatPro™ can be passed to IS1100 Innolytix® QA analysis software, which produces trend charts, pass/fail views and audit-ready reports without anyone re-keying results into a spreadsheet.
