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 calcium 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 four easy steps:
Marine Calcium Checker® HC – HI758
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 Magnesium Checker HC Handheld Colorimeter – HI783
The HI783 Marine Magnesium Checker HC is a handheld colourimeter that uses the Beer-Lambert principle to determine the concentration of magnesium colourimetrically. The HI783 is designed specifically to measure magnesium levels in saltwater aquariums or marine biology applications. The 1000 to 1800 ppm range is ideal for coral/fish or fish-only aquarium maintenance.
- Ideal for aquariums and marine biology
- Easier to use and more accurate than chemical test kits
- Small size, big convenience
Marine Nitrate High Range Checker® HC – HI782
The HI782 Marine Nitrate High Range Colorimeter is specifically designed to quickly and accurately determine high levels of nitrate for saltwater aquariums and marine applications. With a digital readout, there is no more struggling to determine colours visually.
Features:
- Measurements with a range up to 75.0ppm
- Less complex laboratory-grade accuracy – Requires only 1 reagent
- Simple, intuitive digital operation
- Compact and precise whether at home, at work, or on-the-go
Marine Nitrate Low Range Checker® HC – HI781
The HI781 Checker® HC (Handheld Colorimeter) is a simple, accurate, and cost-effective way to measure nitrate in your saltwater aquarium.
Features:
- Take our portable handheld colorimeter anywhere.
- Simple, one-button design makes getting your results easy.
- Improve your technology and upgrade from your standard test kit.
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 pH Checker® HC – HI780
Get accurate water testing results with the HI780 Marine pH Colorimeter. With a digital readout, there is no more struggling to determine colours visually. This pH tester’s compact design fits in your pocket or stores easily in your shop.
FEATURES:
- Easier to use and more accurate than chemical test kits.
- One-button operation makes getting your pH results simple.
- Great for aquariums and marine environmental testing.
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:
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.
Phosphate Ultra Low Range Checker® HC – HI774
The HI774 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate from 0.00 to 0.90 ppm. 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 HI774 provides quick, accurate results in a few easy steps.
Features at-a-glance:
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Aquariums, Environmental, Aquaculture, Water Quality
Total Chlorine Checker® HC – HI711
The Hanna Total Chlorine Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely on the human eye to discern differences in colour. 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 Total Chlorine Checker® uses a fixed wavelength LED and silicon photodetector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
