Horizontal Water Sampler
Horizontal Water Samplers are ideal for thin-layer temperature and chemical stratification monitoring. The messenger activated horizontal release mechanism is easy to load and provides reliable closures. It is important to move the sampler from side to side at the desired stratum to ensure sufficient "flow-thru" before closure.
Vertical Water Sampler
Sample tubes are vertically oriented to "free-flush" until desired depth is reached. The release mechanism provides reliable messenger activated sampler closure. Balls are loaded separately and held open during deployment by a spring-loaded release pin.
A second, tethered, messenger can also be attached to the release mechanism. When a messenger sliding down the line impacts the anvil of the release pin, the balls (under tension of a latex band) are released and pulled inside tube brushings while the suspended messenger is released actuating the closure of deeper bottles, attached to the same line, for serial ("in-series") collection of water at various depths.
These sampling cylinders are constructed using clear polycarbonate tubing which has considerably higher impact resistance than materials used in other similar type samplers. A liquid-spirit filled, armored thermometer is mounted inside the sample tube for instant temperature measurement.
