Hanna (HI758) Marine Calcium Checker Test Kit - Saltwater Aquariums
HI758 Marine Calcium Checker Test Kit
Precision colorimetric calcium testing for saltwater aquariums using the Zincon method with pre-measured reagents
The HI758 Marine Calcium Checker delivers fast, accurate calcium measurements for reef aquarium maintenance using Hanna's proven colorimetric technology. Each kit includes 25 tests with pre-measured reagents that follow the Zincon Method, producing a blue tint for measurement in the 200-600 ppm calcium range.
Designed for Marine Aquarium Precision
Pre-Measured Reagents
Each test includes precisely measured reagent bottles and packets, eliminating guesswork and ensuring consistent, accurate results every time
Zincon Method Chemistry
Proven colorimetric reaction produces a blue tint proportional to calcium concentration for reliable measurement in saltwater environments
Optimized Range
Calibrated for 200-600 ppm calcium detection, covering the critical range for coral health and reef aquarium stability
Quality Traceability
Each reagent clearly marked with lot number and expiration date, manufactured in state-of-the-art facilities with high-purity chemicals
Simple Procedure
Add 1 mL of first reagent to sample, follow with second reagent packet, and the HI758 Checker automatically determines concentration
25 Tests Per Kit
Complete reagent set provides 25 individual calcium tests, ideal for regular monitoring of reef aquarium water chemistry
Reagent Specifications
The HI758U-26 replacement reagents are specifically designed for use with the Hanna HI758 Marine Calcium Checker HC colorimeter. Ideal for saltwater aquariums, reef systems, and marine environments requiring regular calcium monitoring. Each kit contains bottle and packet format reagents for 25 complete tests following the Zincon colorimetric method with results displayed in ppm calcium.
Hanna Instruments manufactures laboratory-grade testing equipment trusted by aquarium professionals and hobbyists worldwide for accurate water chemistry analysis.
