Widely used by organisations involved in large-scale emergencies or simple water quality testing projects, the Potatest is a lightweight microbiological test kit offering low-cost, rapid response testing of basic water quality parameters.
Designed to complement the increased emphasis now being placed upon water safety plans (WSPs) and their role in assessing and managing risk throughout each step of the drinking water supply process:
Removable water safety kit (WSK) – contains instruments and visual test equipment to determine whether a full microbiological verification is required
Rapid field microbiological analysis –using membrane filtration protocols for screening of faecal and/or total coliforms
Supplied with consumables and parts sufficient for processing/analysing 200 samples
Wagtech incubator with consumables for 200 tests for thermotolerant/faecal coliforms or total coliforms. Optional Nutridisk capability for additional parameters including faecal streptococci, pseudomonas aeruginosa, and E. coli
Physico-Chemical Parameters
Free chlorine, combined chlorine, total chlorine, turbidity, pH
Test Protocols
37°C and 44°C temperature selections, user selectable time profiles, automatic resuscitation period profile
Temperature Stability
