🔬 Hofun Household Accuracy Measurement Test Kit: Professional Measure & Inspect Review

The meter is fine. Simply press the power button and submerge it in the water up to the top of the slot. Read something, shake to remove water, turn off, dry, put the lid back on and it's ready for next time. Cheaper, faster, easier and more accurate than test strips.

Completed all required calibration steps and appears to be ready for use. After getting some strange readings regarding my hydroponic tank, I decided to compare it to some known values. Distilled water should have a pH of just under 7. This meter reads 9.1. I then tested it with white vinegar, which should be around 2.5. My levels were 1.3. I returned the item and am planning to go back to using paper test strips or liquid tests and save a few bucks with peace of mind.

I used this to measure the pH of kombucha. I've been using it for about a month and have found that the accuracy doesn't last long. Unfortunately the last day of return was June 10th. If I could still return that counter, I would. I will purchase another gauge and watch the return window if it doesn't suit my needs. I have worked in a clinical laboratory and am familiar with the use of this type of instrument. I believe that the counter is not working properly, not the user of the counter.
