WaterSam - Model WS 98 -Wall-Mount Sampler
The WS 98 is a compact sampler for indoor applications that do not require cooling. It features the same range of functions as larger, stationary samplers. Typical WaterSam® quality and performance in a compact package. Housing made of high-value 316Ti stainless steel as standard; well suited for use in demanding environments. Compatible with all WaterSam sampling systems; even as a douple sampler for sampling from two different points. Suitable for refitting existing samplers (including those from other manufacturers); optionally with connections such as cooling, etc.. Can be combined with a commercially available refrigerator for low-cost cooling of composite samples. Optional XY Distributor in a support frame for discrete sample distribution to a variety of bottle combinations. Optional rinsing of complete sampling line with clean water.
Although designed for indoor applications, the WS 98 is standard-equipped with a high-grade stainless steel housing (AISI 316Ti) and IP65 protection for the controller and technical compartment, making it suitable for a variety of challenging environments.
The vacuum sampling system in the WS 98 ensures maximum accuracy and can draw samples from depths of up to 7 metres, or up to 30 metres with optional equipment. Several optional sampling systems designed for specific applications are available, and can even be operated in pairs to create a double sampler.
If an inexpensive solution for composite sample refrigeration is needed, the WS 98 can be combined with a common household refrigerator.
The WS 98 can also be used to retrofit an old or defective sampler cabinet from another manufacturer by utilizing the WS 98 as a replacement controller and sampling system.
The WS 98 provides you with a compact, flexible and high-value sampler with capabilities which can be expanded at any time in the future.
The WS 98 is a sampler of uncompromising WaterSam quality and performance, designed to be a compact and
economical unit simpler sampling applications.
