Hanna Marine Calcium Checker

The Hanna Marine Calcium 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 absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Marine Calcium 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.

Compact, Portable Design

The Hanna Marine Calcium Checker features a compact and portable design, making it easy to carry and use in the field or in a home aquarium. Its small footprint ensures convenience without compromising performance.

Built-in Timer for Accurate Testing

Equipped with a built-in timer, the Hanna Marine Calcium Checker® ensures precise measurement timing for consistent results every time. This feature helps reduce user error and improves testing reliability.

One-Button Operation

The device is designed for one-button operation, allowing even beginners to perform calcium measurements quickly and efficiently. Minimal training is required to obtain accurate readings.

Easy Four-Step Testing

The HI758 Checker HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure calcium, a crucial element for the development of calcium carbonate skeletons in coral reefs. Designed as a more precise alternative to chemical test kits, the HI758 delivers fast, accurate results in just four easy steps.
