TST-70 type permeameterDetailed product description：

TST-70 permeameter

This instrument is manufactured based on the Jima permeameter, with an inner diameter of Φ 100+0.22mm. It can be used to measure the permeability of sandy soil and non cohesive soil containing a small amount of gravel under constant water head. This instrument mainly consists of a water permeable component and a compaction component. The water permeable component consists of a cylinder body, a permeable plate, a scale plate, a pressure measuring tube, etc. Three pressure measuring tubes are installed on the scale plate with a spacing of 100 ± 0.44mm. The water level can be read by the scale of the scale plate installed on the cylinder. Copper wire cloth is installed inside the joint of the pressure measuring tube to prevent fine sand particles from flowing out with water during the test. There is a drainage hole at the lower part of the infiltration tube, and loosening the bolt can release the sewage. The compaction part is equipped with a wooden hammer to compact the sample.

The complete set of instruments, accessories, and spare parts includes one water permeable component, wooden hammer, pipe clamp, pressure measuring tube, rubber tube (1.5 meters long), and two pieces of copper wire mesh 0.5 × 0.6 (20 #) and 1 × 1 (40 #) respectively
