What is the Hanna Marine pH Pocket Checker?
The Hanna Marine pH Pocket Checker is a handheld colorimeter designed to provide fast, reliable, and cost‐effective pH measurements specifically in seawater. It offers a more accurate and user‐friendly alternative to traditional chemical test kits and is ideal for marine biology applications and aquarium maintenance. The device operates using a simple four‐step process and is tailored for testing the pH range commonly found in ocean surface water (7.5 to 8.5).
Key Features:
- Accurate pH measurement designed specifically for marine environments
- Compact and portable design for on‐the‐go testing
- Easier to use than chemical test kits
- Fast, digital results with one‐button operation
- Ideal for use in marine biology, aquariums, and research
What are the features and benefits of using the Hanna Marine pH Pocket Checker?
The Hanna Marine pH Pocket Checker is ideal for monitoring seawater pH, especially in environments where ocean acidification and changes in carbonate chemistry can affect marine life. pH changes, even minor, can impact marine organisms' ability to grow, reproduce, and form calcium-based skeletons like corals. This tool allows precise monitoring to support healthier ecosystems and research accuracy.
Quick Testing Steps:
- Zero the checker with a 10 ml seawater sample
- Remove the vial and add the reagent
- Reinsert the vial into the checker
- Press the button to instantly read the pH level
