PTW10030
Designed for routine testing in the field, the Wagtech Potakit includes a combination of visual and digital test instruments that offer an affordable yet accurate testing solution.
The Potakit is the kit of choice for NGOs and water technicians implementing small-scale rural WASH programmes and for organisations with limited funds but who still wish to conduct an accurate assessment of key drinking water quality parameters in the field:
- 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
- The Potakit is supplied with consumables and parts sufficient for processing/analysing 200 samples. For replacement consumables and accessories, download the Wagtech brochure in the Resources section to view the details and obtain the relevant ordering codes.
