The Pneumatic Piezometer is capable of monitoring pore pressure up to 14,000kPa. Combines the Features of high accuracy and reliability, small size, low cost and extremely low diaphragm displacement (0.002cc) with the ability to be continually monitored. Ideal for construction site and preload monitoring. Accuracy depends on the readout used.
