Soft plastics, felt, leather, and similar materials generally fall into this same range. PTC® s Model 306L meets or exceeds current ASTM D2240 Specifications.
The instrument has a low glare aluminum dial with bold, easy to read numbers. The durometer comes standard with a Max Hold hand which retains the peak reading. A top knob with 8-32 threads permits both easy handheld use and attachment to test stands or the accessory

CALIBRATION CHECK
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.
