• Hanna Marine Alkalinity (dKH) Checker HC - HI772

    The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.Features at-a-glance: Easier to use and more accurate than chemical test kits...

  • American Marine Pinpoint ORP Monitor

    The PinPoint ORP Monitor will measure the ORP (oxidation-reduction potential, or REDOX) of your system. It is popular with those who use ozone gas or potassium permanganate as an artificial oxidation agent in fresh or saltwater. Constant monitoring of the ORP is useful in keeping tabs on the overall health of a system, as a drop in ORP often precedes visual or other indications of trouble. Many serious marine enthusiasts who do not use ozone gas use this meter to judge the overall health of their reef systems. This unit features a 1mV digital resolution and a platinum electrode. The range is ?... [Read More]
