The HI758U-26 are the replacement reagents for the HI758 Marine Calcium Checker® HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

Details:

The HI758U-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Calcium Checker® HC. These reagents follow the Zincon Method in which the reaction causes a blue tint in the sample. By simply adding 1 mL of the first reagent to the sample, followed by a packet of the second reagent in the HI758U-26 set, the reaction will take place and the HI758 will determine the concentration from the color that is produced. The results will be displayed in ppm of calcium. These reagents are designed to be used with samples that have an expected range of 200 to 600 ppm calcium.

Manufacturer Info

Hanna Instruments USA Aquarium Supplies
Hanna Instruments is a leading manufacturer of analytical aquarium instrumentation. They were founded in 1978 and are headquartered in Woonsocket, Rhode Island. When Hanna introduced pH Electronic Paper in 1986 it literally revolutionized the world of testing by allowing millions of people in various industries to test for pH in a simple, accurate and affordable way. Hanna employees are constantly challenging themselves to improve on existing technology and to invent new testing techniques with the common goal to simplify analytical testing. This applies not only to instrumentation, but also to sensors development, reagents and chemicals. Hanna also believes in controlling the quality of their products from inception to delivery so they manufacture everything themselves, from meters and electrodes to chemical reagents and buffer solutions.

A
Hanna sells calibration kits but we don't have them on our site at the moment. They can be purchased directly from Hanna. Although it might be worthwhile noting that the kit only tests the accuracy of the checker, it does not calibrate it. If the checker is out of range, it has to be sent to Hanna for a correction/replacement. https://hannainst.com/hi758-11-marine-calcium-checker-calibration-set.html
