Potakit® + Basic Portable Water Quality Laboratory PTW 10030

Designed for routine testing in the field, the Potakit® + includes a combination of visual and digital test instruments that offer an affordable yet accurate testing solution.

The kit of choice for NGOs and water technicians implementing small-scale rural WASH programs and for organizations with limited funds but who still wish to conduct an accurate assessment of key drinking water quality parameters in the field. Key features of the Potakit® + include:

  • Intuitive microbiological analysis – simple-to-use incubator with unique audible prompts for ease of operation and USB connection for data download
  • Complete physico-chemical analysis – visual testing apparatus for turbidity, Ammonia, Arsenic, Free and Total Chlorine, Fluoride, Nitrite and Nitrate plus Pocket Sensors for pH and conductivity
  • Ergonomic kit layout – all key components laid out logically and conveniently to guide users through the test protocol

The Potakit® + provides cost-effective drinking water testing for a wide range of circumstances and is an ideal resource for WASH program implementation.
