Coating Thickness ProbeAerosol Probe IS9571
Measure internal and external coating thickness on aerosol cans without destructive testing.
The IS9571 Aerosol Probe is Innosen’s high-precision solution for measuring internal and external lacquer thickness on aerosol cans — without destructive weigh-strip-weigh testing. Designed to work with the IS860 CoatPro™ coating thickness gauge, its narrowed probe tip and flexure system deliver exceptional repeatability and reproducibility (R&R) across a wide range of aerosol profiles, opening sizes, and lengths up to 375 mm.

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 Aerosol Probe IS9571, 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 CANMAKING QA TEAMS
What is the IS9571 Aerosol Probe?
The IS9571 Aerosol Probe is Innosen’s accessory probe for the IS860 CoatPro™ coating thickness gauge, purpose-built to measure internal and external lacquer thickness on aerosol cans without destructive weigh-strip-weigh testing. Its narrowed probe tip and flexure system deliver accurate results across a wide range of aerosol profiles, opening sizes, and lengths up to 375 mm.
Why avoid weigh-strip-weigh testing for aerosol coating measurement?
Weigh-strip-weigh is a destructive method — it damages the can to get a reading. The IS9571 Aerosol Probe measures lacquer thickness directly and non-destructively, so aerosol makers get precise coating data without sacrificing product.
Can the IS9571 measure internal and external coating in the same setup?
Yes. The IS9571 Aerosol Probe takes dual-surface measurements, reading both the internal and external lacquer coating in one setup, rather than requiring separate passes.
What aerosol can sizes does the IS9571 Aerosol Probe support?
The probe accommodates aerosol cans up to 375 mm (14.76") in length. Can diameter varies by profile — consult Innosen for your specific can dimensions.
Does the IS9571 Aerosol Probe work with the IS860 CoatPro™ gauge?
Yes. The IS9571 Aerosol Probe is designed to work with the IS860 CoatPro™ coating thickness gauge, with readings logged through IS1100 Innolytix® data collection software, included with CoatPro™.
How does the IS9571 keep readings consistent from measurement to measurement?
A rotary flexure system gives stiction-free readings, a force-multiplier flexure maintains consistent contact pressure, and a dead-weight design resists temperature-based variation — together delivering stable, repeatable results.
