Easier handling and more repeatable readings are the results of PTC®'s Ergonomic Research. The durometer is easy to grip and the 1.25 diameter base has a large landing area for increased stability and maximum repeatability.
The instrument uses a dial gauge with a full
360º scale with bold, easy to read numbers. The
dial scale can easily be read to within a 1/2-point.
Accuracy of the instrument is ±1 point. These
durometers meet or exceed all aspects of ASTM
The 502D durometer and the
409D Ergo durometer
were chosen as the standard by the Oil & Gas Industry for pipeline coating hardness.

For a complete calibration check of mainspring, and visual and mechanical check of indenter, the instrument should be returned to PTC® (see Guarantee & Calibration Service) or refer to ASTM D2240 Specifications. PTC® recommends the unit be returned at least every 12 months for this
check. For a quick field check, follow the guideline below. Under no circumstance should a test block be used as a standard to calibrate a durometer.
1. The pointer should read zero when no force is applied to the indenter of the durometer.
2. Hand hold the durometer and insert the indenter into the hole of the calibrated test block. Apply enough force to make firm contact between the top surface of the test block and the base of the durometer. The dial reading should agree with the value stamped on the check block (±1). Several tests should be made and the results averaged.
3. The indenter must protrude 0.098 to 0.100 inches below the base of the durometer.
4. When the indenter is fully displaced, the durometer should read 100 points. Use care as to not damage the tip of the indenter.
