The HI758 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure calcium. Required for the development of calcium carbonate skeletons of coral reefs, calcium is a crucial component of marine waters. Designed as a more accurate alternative to chemical test kits, the HI758 provides quick, accurate results in four easy steps.
Marine Calcium Checker® HC Reagents (25 Tests) – HI758-26
The HI758-26 are the replacement reagents for the HI758 Marine Calcium Checker® HC. These high-quality reagents are manufactured in Hanna Instruments state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
Marine Nitrite Ultra Low Range Checker® HC – HI764
The Hanna Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. The Checker® is both accurate and affordable.
Marine Nitrite Ultra Low Range Checker® HC Calibration Check Set – HI764-11
The Marine Nitrite Ultra Low Range Checker® HC Calibration Check Set – HI764-11 provides a simple solution to validating the Nitrite Ultra Low Range Checker® HC – HI764 that has a range of 0 to 200 ppb.

Marine Phosphorus Ultra Low Range Checker® HC – HI736
The HI736 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphorus in marine systems including reef tanks. Phosphorus is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI736 provides quick, accurate results in four easy steps:
Marine Salinity Tester – HI98319
Designed to bring simplicity to salinity testing during any process, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.). The HI98319 Marine Salinity Tester comes with all the necessary calibration solutions and batteries, everything you need to get started testing the salinity of your aquarium right away.
Phosphate Low Range Checker® HC – HI713
The Hanna Phosphate Low Range Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphate Low Range Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
