Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Pool Water Testing & Kits
Very impressed with this nifty pH meter! Very, very reasonable price. I have rechecked calibration (I purchased more buffer powders to calibrate machine) after 2 weeks of using in a spa pool. No re-calibration needed as it read perfectly. It will only read to one decimal place but this is accurate enough for my purpose. Highly recommend for value.
