Overview
The Cometech GS-709N A-type Hardness Tester is an analog (pointer) durometer designed for hardness measurement of soft, non‑metal materials by applying a specified force and reading the dial value.
It is positioned for normal rubber and plastics where Shore D is below 20, making it a practical choice for routine QC checks of softer compounds and parts.
For accurate reporting, the recommended procedure is to test multiple positions and repeat measurements (typically 5–10 times) and then record the average value.

Recommended test workflow (important)
- Repeat the test 5–10 times and record the average value for correct hardness reporting.
- Test 5 or more positions on the specimen and average the results to reduce local variation effects.
- Use a fixed-pressure load stand to apply an accurate, consistent load and improve repeatability vs handheld-only measurement.
