The Water Sampler allows you to collect a one litre water sample from a depth of between five and 20 metres. It consists of a collecting tube which is attached to a 20m line marked in 0.5 and 1 metre increments. Each end of the sample tube is fitted with a plunger which seal the ends of the tube when the triggering device is activated. The trigger is activated by sending a brass messenger down the line when the sampler is at the correct depth. The sampler can then be retrieved without the risk of the contents being contaminated with any water from an intermediate depth. A lead collar ensures a rapid descent and prevents the sampler from moving around too much as a result of water currents. A drain outlet in the sampler allows aliquots of water to be removed easily.
Please note that using the messenger when the water sampler is at a depth of less than five metres may damage the trigger mechanism.
