WaterSam - Model WS 316-EX - Stationary Water Sampler with Ex Zone II Interior
Especially in the chemical industry, sample media can contain components which present an explosion hazard. It is often sufficient however to minimize the risk of ignition at the sampling point itself and around the stored samples. A WS 316 variant was developed for this application, in which the sample storage chamber is classified according to standards for ATEX Ex-Zone 2. As with other samplers, the samples can be safely stored at a preset temperature. The huge cost savings and advantages in quality relative to a fully Ex-certified sampler have made the WS 316 Ex 2 Interior the choice of market-leading international companies.
