Water Sampling
Niskin type water sampler is used for collection of water samples. It has the capacity of five litres. The water sampler is sent to the desired depth, in the vertical position by clamping it to a rope of 4 to 6 mm diameter. The brass messenger is allowed to slide along the wire and strike the top of the push rod, which activates the closure of the sampler underwater. Thus the sample is collected.
