New Equipment

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: Independent from electricity, robust, easy to use, easy to transport, not susceptible to errors, independent from inappropriate consumables, affordable.
