A variety of samplers are available for your specific needs in sampling. These sediment samplers can measure solid elements found in wastewater and chemical treatment plants, and food processing. The lower section includes a spherical valve that allows liquid to enter in the unit once reduced in the sampler and seals it when raised from the liquid. The upper section has a nylon cord that helps during the sampling process. The central section links the upper and lower parts. Length of 15 feet for each sampler. The CP-B01386WA has a UV stabilizer that reduces degradation of the material caused by UV radiations.
