American Marine Pinpoint Aquarium Supplies
American Marine was founded in 1989 by a devoted aquaculturist who was passionate about quality and precision. Back in the late 80s, critical water quality parameters were mostly tested with colorimetric test kits. Some digital instruments were borrowed from university or laboratory sources with mixed results but always a high price tag. Expensive European aquarium equipment was always a disappointment when it finally arrived. Inexpensive "pens" gave no better results than color test kits and prematurely failed even when testing for approximate readings.
Using the most current technology and design, American Marine introduced Pinpoint Monitors, which have become the most respected line of digital instruments in the aquaculture business. American Marine was the first to introduce a 2-year warranty on each and every monitor. For every purpose, from a goldfish bowl to a salmon hatchery, Pinpoint Monitors are called into duty every day because of their rugged design, precise readings and reasonable cost. American Marine has sold Pinpoint Monitors on every continent. Each monitor is powered by a standard 9 volt battery that is available worldwide.
