Product Description

Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter, depending on its source and treatment. Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures. Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling. The HI 758 Calcium Checker HC is extremely simple to use. First, zero the instrument by adding Reagent A, deionized water and 0.1 mL of sample into the vial. Insert into the HI 758 and press the button. Next, remove the vial and add Reagent B and shake to dissolve. Reinsert into the Checker HC and press the button to read the calcium concentration in ppm on the display. Use for quick and accurate on the spot analysis. Single button operation: zero and measure. Range: 200 to 600 ppm. Resolution: 1 ppm. Accuracy at 25 degree C: +/-6% of reading.

Expert Review

Review by: Nathan K.
Actually, I am overwhelmingly excited to have gotten a hold of the Hanna Instruments HI758 Marine Calcium Checker Test Kit - Saltwater Aquariums. It’s not particularly effortless to grab a suitable piece of this nature even in an ordinary store, so I value the seller’s efforts of bringing us the product of an actually favourable quality at such a low price.

Corporate responsibility is an important issue I’m paying attention to in a manufacturing company, and all of my purchasing decisions are heavily shaped by the manufacturer’s actions. So preparatory to favouring the seller with my order I took the liberty of looking up the manufacturer and the company’s code of ethic.In fact, I was satisfied to learn that the company staff is performing in a safe production condition and that no human rights are violated during the production process. I’m sorry to say that nowadays it is not happening at all, and I personally can’t support the idea of supporting a company that reaps benefits from the employees in an improper and wrongful manner.

I reckon you will also find it worthy to learn that the product was designed as the result of ethical sourcing of raw materials, and with the use of environmentally friendly methods as well. No doubts, it is a good reason to make a purchase, particularly given that the product induces no allergy or any typical health conditions thanks to the superior quality of the raw stock.

When my order was finally delivered, I got the opportunity to make sure of the great quality of Hanna Instruments HI758 Marine Calcium Checker Test Kit - Saltwater Aquariums with my own eyes. I have tested it already, and I’m greatly satisfied with the performance, so it’s safe to say the product truly deserves a five-star review.
