Hanna checker (pH)
The Hanna pH checker is a digital pH meter. This model has a range of 0-14.
How to test:
1. Remove the probe from the buffer solution.
2. Submerge the probe halfway into the water or water sample.
3. Turn on the probe and wait for readings to settle.
4. Record readings and remove the probe from the sample. Turn off the probe. Clean the probe gently, wiping it down or letting it dry. Place the probe tip in the buffer solution. Do not push the prob all the way down into the bottle with buffer solution. Let the probe tip be submerged about halfway into the buffer solution.
