The ground water sampler (Model: GWS-1) has technically been designed for the application in connection with the water level indicator. With this combination-design, it is possible to obtain liquid samples from any desired depth. Basically, the liquid sampler consists of three parts - piston, tube and releasing weight. In order to get a liquid sample, the tube is hooked above the piston first and then lowered. When the desired sampling depth is reached by means of the measuring tape, the weight on top is released, which slides downwards along the cable to the top of the tube. Here, the closing mechanism is activated and the tube is automatically slided over the pistons. The liquid sample can now easily be pulled out by means of the supporting drum and the liquid withdrawn by the attached faucet. with 2" tube diameter (capacity 0.45 liters; dimension: 49mm x 1750mm)
