Palintest Potatest+ PTW10005 Microbiological field lab

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
Microbiological Capacity 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 ± 0.1°C
Temperature Control Laser-trimmed thermistor pair with automatic temperature validation
User Interface On screen and audible prompts available in English, French, Spanish and Chinese
Data Log Last five incubation cycles performance report
Connectivity Micro-USB connection to Windows and Android devices for data download
Power Supply Replaceable sealed lead acid battery with mains, vehicle and external charging options
Power Consumption High thermal efficiency heating system, five full cycles from a fully charged battery
