This kit allows the quantification of E.coli and other coliforms for a large number of water samples in the laboratory. LETZTEST has developed this kit which is perfectly suited for analytical laboratories located in areas with limited infrastructure. The kit is still easy to transport and can be operated without electricity in the event of a power failure. It is therefore ideal for setting up a project laboratory in a remote location. Furthermore, very low running costs are possible with this kit.

Advantages:

• All parts inside kit made in EU
• Very low running costs of ~0,50€/sample possible by replacing two consumables with reusable solutions.

Simple, Safe and Independent! The Visual Color Comparator Test is an easy to use tool for measuring free/residual chlorine, total chlorine and pH (acidity) of water samples which is very often convincing in practice!

Why measuring chlorine and pH? In many cases testers want to know if a water was disinfected or if the residual chlorine (=free chlorine) level is still sufficient to protect the drinking water from recontamination. The Ideal level of free-residual chlorine is said to be 0,2-0,5 mg/L. Desinfection with chlorine is more effective at a pH value below 7,5.
