Coating Thickness Probe

 

IS9651 Hoverprobe ® II

 

Measure coating thickness on flat metal sheets without operator variance.

 

The IS9651 Hoverprobe ® coating thickness probe is Innosen’s semi-automatic solution for accurately measuring lacquer, coating, and varnish thickness on flat sheets. Designed to work seamlessly with the IS860 CoatPro Coating Thickness gauge, it forms a complete, highly reliable coating-thickness measurement system (IS1100 Innolytix data collection software included).

By floating into position on a cushion of air and settling under its own fixed weight, the IS9651 ensures every reading applies the exact same pressure to the probe tip. This unique design removes the inconsistency typically caused by manual probe handling.

(Note: The Hoverprobe II also works with SI9600-type coating thickness gauges already installed on your line, ideal for plants transitioning their measurement setup).

 

 

 

REMEMBER: Gauge R&R or gauge repeatability and reproducibility is important in measuring coating thickness because it shows which part of the measurement system is contributing the most to the variation of the measurements, therefore giving the operators ideas on how to ensure quality and cost control.

BENEFITS

COMMON QUESTIONS FROM CANMAKING QA TEAMS

What is the IS9651 Hoverprobe® II?

The IS9651 Hoverprobe® II is Innosen’s semi-automatic coating thickness probe for flat metal sheets. It floats into position on a cushion of air and settles under its own fixed weight, so every reading applies the same consistent pressure to the probe tip. Paired with the IS860 CoatPro gauge and IS1100 Innolytix software, it delivers fast, repeatable lacquer, coating, and varnish thickness measurements without operator-to-operator variance.

What problems does inconsistent probe pressure cause in coating measurement?

Inconsistent pressure during coating measurement results in noisy, inaccurate, and hard-to-trust data. Manual probes require the operator to apply the exact same pressure every time; squeezing too hard or too soft alters the reading even if the actual coating thickness remains unchanged. This variance makes it difficult for quality assurance teams to tell whether a process drift is real or simply a measurement error.

How does the IS9651 Hoverprobe coating thickness probe remove measurement variance?

The IS9651 Hoverprobe® II removes measurement variance by standardizing the physical pressure applied during testing. At the press of a button, the probe floats into position on a cushion of air. When released, it settles onto the flat sheet strictly under its own fixed weight. This guarantees that the exact same precise load is applied to the probe tip on every single test, delivering perfectly repeatable readings across different operators.

What upgrades does the Hoverprobe II bring over the original IS9650?

The IS9651 Hoverprobe® II features several hardware and performance upgrades designed to improve durability and reduce downtime on the plant floor:

  • More robust cable design: Cables and connectors are completely encased in a protective jacket, making them highly resistant to cuts and damage from factory rubbing or scraping.

  • Redesigned, quick-connect probe tips: Tips are pre-fitted in quick-connect sockets, making them easier and faster to replace while significantly reducing settling time after a tip swap.

  • Improved metal base: Engineered to be more durable and highly scratch-resistant.

  • New dual-probe measurement method (optional): The metal base can now serve as a second probe. This removes the need for a traditional crocodile clip and prevents accidental sheet damage.

  • Reduced maintenance requirements: The updated design features fewer internal wear parts and is far less susceptible to overpressure damage than the original IS9650 model.
