Model 303 ASTM type OOO-S Shore scale durometer measures the hardness of viscoelastic polymers. Applications include motorcycle seats, medical pads and wheelchair cushions for pressure ulcer prevention. equestrian pads, gun recoil pads, and cool gel mattresses.
What is the difference between OOO and OOO-S?
There are currently two types of OOO durometers that comply with ASTM D2240 now recognized in the industry. The two distinct OOO units differ in indenter geometry and extension as well as spring force calibration. ASTM D2240 recognizes both variations of the OOO and OOO-S.
For the best accuracy, use of this durometer with one of our accessory Test Stands is recommended. The Model 470 is compatible with this durometer.

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.
