SKU:
Model 4500MLP

The Model 4500MLP system overcomes the problems associated with the installation of multiple piezometers in a single drill hole. The 4500MLP is lowered into position and a spring loaded apparatus is actuated forcing specially configured piezometer filter elements into firm contact with the borehole walls. The borehole is then grouted from the bottom in one quick and simple operation.*
