The challenge with manual Hegman gauges
Manual Hegman gauge testing is simple in principle: material is drawn down across the gauge, and the point at which larger particles appear indicates the level of dispersion. However, the process can be highly subjective, based on manual readings of the gauge.
-
Human error and interpretation: Different operators can interpret the same drawdown differently. Lighting conditions, visual perception, and even experience level all influence the result.
-
Inconsistency over time: Results may vary between batches, shifts, or laboratories, making long-term comparisons difficult.
-
No digital record: Manual readings leave no audit trail. Once a test is complete, there’s no easy way to revisit or validate the result.
In industries where quality and traceability are critical, these limitations can become bottlenecks.
The automated alternative
Labman’s TIDAS system was designed to take the subjectivity out of Hegman gauge testing. By combining automation with digital imaging and analysis, TIDAS delivers accurate, repeatable, and traceable results every time.
Instead of relying on the human eye, TIDAS captures high-resolution images of the drawdown and uses advanced software to analyse the point of particle appearance. The outcome is objective, consistent, and fully documented.

The benefits of automation with TIDAS
Choosing an automated Hegman gauge platform offers clear advantages:
-
Consistency across operators and sites: Every reading is analysed in the same way, regardless of who runs the test.
-
Traceability and documentation: Each test generates an image and digital record, supporting quality assurance and regulatory compliance.
-
Improved efficiency: Automation speeds up the testing process and reduces the need for repeat measurements.
-
Confidence in quality: Reliable, data-backed results strengthen customer confidence and internal decision-making.
Moving beyond subjectivity
Manual Hegman gauges have served the industry well, but today’s demands for consistency, traceability, and efficiency call for a more robust solution. By automating the process, TIDAS ensures reliable results you can trust.
