Hydraulics Modelling Services Ltd (HMS) have developed a range of monitoring units which can be split into three categories:

• U.K. Regulatory Units
• Portable Units
• Customised Units

Each unit accommodates a filter cartridge that captures the Cryptosporidium oocysts for laboratory analysis.

Our, U.K. Drinking Water Inspectorate (DWI) approved units meet the strict terms of the regulations and we have supplied over 75% of the market to date, including all the large water companies.

Following our experience in producing DWI Approved Cryptosporidium monitoring Units, we can now offer portable equipment in four versions.
