Hanna instruments 3 pack Calcuim, Alkalinity and Phosphate ULR Checkers

The HI774 Ultra Low Range Phosphate Checker® HC (Handheld Colorimeter) is a cost-effective way to measure phosphate in marine systems, including reef tanks. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often out competes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. 

• Take your portable handheld colorimeter anywhere. 
• Simple, one-button design makes getting your results easy. 
• Improve your technology and upgrade from your standard test kit. 

DETAILS

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

In the Box:

H1774 Checker, (2) sample cuvettes with caps, phosphate ULR reagent starter kit for 10 tests, batteries, instructions, and quick start guide.

Hanna Alkalinity Checker:

Get accurate results for your saltwater aquarium with Hanna's simple handheld colorimeter digital test kit.  The HI772 dKH Alkalinity Checker®HC is our most popular selling aquarium product. Our alkalinity colorimeter bridges the gap between alkalinity test kits and advanced instrumentation. Standard test kits have limited accuracy since they rely upon the human eye to match colors. Our handheld colorimeter eliminates the hassle of matching to a color chart by providing a direct saltwater alkalinity result in dKH units.

• Remove the human error from your testing
• No need to count drop or titrate your sample
• Detects color changes your eye cannot
• No calibration required
• Get east, quick and consistent results
• Accurate and affordable
• Cost efficient: Once you purchase the Checker, reagents are sold separately saving money long term

     DETAILS

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

       Most popular reef aquarium product

       About one minute to preform a test

       Comes with 25 tests

HI772 Checker® is supplied with (2) sample cuvettes with caps, alkalinity reagent starter kit for 25 tests (1 bottle of alkalinity reagent), (1) 1 ml syringe and tip, ­­­ battery, instructions, and quick start guide.

Hanna Calcium Checker:

Our handheld colorimeter eliminates the trouble of matching to a color chart by providing a direct saltwater calcium result in ppm CaCO3.

• Remove the human error from your testing
• No need to count drop or titrate your sample
• Detects color changes your eye cannot
• No calibration required
• Get easy, quick and consistent results
• Accurate and affordable
• Cost efficient: Once you purchase the Checker, reagents are sold separately saving money long term 

DETAILS

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 HI758U provides quick, accurate results in a few easy steps.

Features at-a-glance:

• Easier to use and more accurate than chemical test kits
• Newly updated with 100μl mechanical pipette (HI731339P)

The HI758U Marine Calcium Checker HC® uses a 100 to 1 dilution for analysis and thus requires deionized or distilled water absent of calcium to function correctly. Calcium can be found in many freshwater sources and this any amount present in the water used at the C1 phase can cause false high readings. In addition, many hobby grade reverse osmosis deionized water systems may not adequately remove calcium. This can vary based on the types of filters used, their effectiveness and frequency of replacement. We recommend using deionized water with low conductivity or pure vapor distilled water commonly found in most pharmacies.

Never use tap water to clean your cuvettes. This is especially important for the HI758U Marine Calcium Checker as calcium is commonly present in tap water and residual amounts present in the cuvette will elevate results produced by the Checker.

Calcium Checker Troubleshooting Tips

1. Never rinse your cuvettes with tap water or saltwater
2. Use pure vapor distilled water from your local pharmacy at C1 phase. RODI water from home filtration units may not be suitable for this test as calcium can easily permeate through your filter membranes. 
3. Clean your cuvettes with distilled or deionized water absent of Calcium that is going to be used for C1 phase dilution. 
4. Measure out 9 ml of distilled or deionized water for C1 phase
5. Make sure no excess aquarium sample saltwater is on the tip of the pipette. Only administer the saltwater that is sucked into the pipette tip. 

HI758 Calcium Checker is supplied with (2) sample cuvettes with caps, calcium reagent starter kit for 25 tests, dropper,1 ml syringe with tip, 100 microliter pipette with tip, plastic pipette, battery, instructions and quick start guide.
