- What is the difference between the Hanna pHep 4 and the pHep 5 pH meters? Do you have pH calibrating solutions?
- Thanks for your question. The Hanna pHep 4 and pHep 5 meters are very similar in design, but the pHep 5 offers higher accuracy and resolution. pHep 4: ±0.1 pH accuracy, resolution of 0.1 pH pHep 5: ±0.05 pH accuracy, resolution of 0.01 pH Both feature automatic temperature compensation, replaceable electrodes, and waterproof construction. Yes, we do carry Hanna pH calibration solutions in multiple buffer values (commonly pH 4.01, 7.01, and 10.01).
- Does this probe work/accurate in saltwater?
- This probe will provide accurate readings in salt water.

I have used this product for many years and have found it to be reliable and easily maintained. The two-point calibration is convenient and easy. I am looking for a similar unit that has three-point calibration.
