Description
In pool water, too high a pH can lead to development of dangerous bacteria and even algae growth. The pH in a pool or spa should be between 7.0 and 7.6! Such accurate values can only be monitored with a digital pH meter. Test strips and test kits are not suitable for this purpose!
The HI779 is a checker-photometer that allows you to quickly, easily and moreover accurately measure pH in swimming water, according to the recognized phenol red method. Like a tester, the checker does not need to be calibrated with buffers, nor is there an electrode that needs to be stored in preservative liquid.
Developed as the accurate alternative to chemical test kits, the Hanna Instruments Checker gives fast, reliable measurement results.
- Easier and more accurate than chemical test kits
- Practical pocket size
- Clearly readable display
- Simple one-button operation
- Automatic shutdown
- Operates on a single AAA battery
Before using the Hanna checker for pH fresh water
Remove the unit from its packaging and check that no damage has occurred during transport. If there is any damage, contact your supplier immediately. This checker comes with:
- Cuvettes and caps (2)
- Starter kit reagents (approx. 100 tests)
- 1.5 V AAA battery
Keep all packing material until you are sure that the instrument is functioning properly. All defective items should be returned in the original packaging with the accessories provided. Before using this instrument, ensure that it is suitable for the environment in which it will be used. For your safety and that of the instrument, do not use or store the instrument in hazardous environments.
Tips for accurate measurements
- It is important that the sample to be measured does not contain suspended particles or is colored.
- The cuvette should be clean and dry.
- Shaking the cuvette may create air bubbles that give inaccurate readings. For an accurate measurement result, remove the air bubbles by gently moving the cuvette in circular circles or by gently tapping the cuvette.
- After adding the reagents, immediately proceed with the measurement procedure.
- Rinse the cuvette immediately after use to avoid deposition of reagents (= dye). The cuvette must always remain clean inside as well.
