Our Water Test Kits

Simplicity in highest quality, developed from practice and made in Germany. More than 10 years of practical experience have taught us the problems presented by water quality testing in regions with limited infrastructure. We have often found ourselves in the field or in the laboratory, dealing with unfavorable conditions and inappropriate equipment that caused more trouble than it was worth. As a result, we developed our own equipment which is: easier to use, more environmentally friendly, easier to transport, more robust, independent from electricity, independent from inappropriate consumables, more affordable.
