Product Description
we offer two kinds of piezo single crystal reference disc for calibrating piezo d33 meter at low d33 range
1. Piezo Single Crystal Ceramic Reference Disc, 10 mm x 10 mm x 0.5 mm, d33 ~ 25, similar to PVDF, PVDF-TrFE
2. Quartz 9.5 mm diameter and 1 mm thickness, d33 ~2.2
Both materials are NOT sensitive to temperature or force and they can be used as reference sample to adjust d33 meter and test low-d33 samples such as PVDF, PVDF-TrFE, etc.
Note: no calibration performed. Value provided as reference. Good as internal reference sample to compare different low-d33 samples.
