Basic Portable Water Quality Laboratory – POTAKIT®+


A basic portable water quality laboratory kit suitable for NGOs and small-scale rural programmes with limited funds. Popular for measuring the basic parameters of drinking water quality in the field, Potakit®+ includes a combination of visual and digital testing instruments.


  • Cost-effective drinking water testing
  • Water technicians implementing small-scale rural WASH programmes
  • Organisations performing basic in-the-field water testing
  • NGOs testing drinking water quality


  • Microbiological analysis with simple incubator that features USB connection and audible prompts
  • Physico-chemical analysis – visual testing apparatus for turbidity, ammonia, arsenic, free and total chlorine, fluoride, nitrite and nitrate; pocket meters for pH and conductivity
  • Field Case – keeps items readily accessible, robust and waterproof
  • Comprehensive but simple to use instruction manuals for all instruments
  • Includes initial consumables needed – replacements are readily available
