E M Supplies have been producing sampling equipment since the 1970’s. The sampling equipment is used by all regions of the Environment Agency, Scottish Environment Protection Agency (Sepa), DEFRA, Environment  Protection Agency (EPA) in Ireland, Northern Ireland Environment Agency (NIEA) and all of the major Water Companies. It is also used in the Brewing, Chemical, Power, Oil and Food Industries for process and Trade Effluent sampling.

The equipment is used by Water Companies for sampling on Sewage Treatment works, Water Treatment Works and both raw water reservoirs and treated water reservoirs. The range of equipment has been produced to meet specific sampling needs and new items are continually being added at the request of customers to meet new requirements and specifications or to solve new sampling problems.
