Product Description
HI783 Marine Magnesium Checker HC is a dedicated handheld colorimeter designed to provide accurate, convenient magnesium concentration measurements in saltwater aquariums and marine biology environments. Incorporating the Beer-Lambert principle, the HI783 utilizes a colorimetric EDTA method with a calmagite indicator, delivering results via a simple blue to violet color transition in the sample cuvette.
- Measures magnesium within a 1000 to 1800 ppm range, ideal for coral/reef and fish-only systems requiring precise control.
- Accuracy rated at ±5% of reading at 25 °C (77 °F), meeting the demands of both research and commercial marine tank management.
- Silicon photocell detection and a 610 nm LED light source offer consistent, laboratory-grade performance.
- Auto shut-off functionality activates after 10 minutes of non-use, preserving battery life.
- Environmentally robust: suited for 0 to 50 °C operating temperatures, up to 95% RH (non-condensing).
- Interference from calcium ions minimized for reliable results; optimal for marine water analysis.
- Compact housing with dimensions 86.0 x 61.0 x 37.5 mm and a lightweight design (64 g) for portability.
- Powered by single 1.5V AAA Alkaline battery, field-ready for laboratory and aquarium applications.
This colorimeter is widely used in industrial and laboratory settings for marine aquaculture, oceanography, and saltwater system maintenance, ensuring that magnesium ion levels remain in optimal range for healthy aquatic organisms and coral calcification.
