Digital pH Meter for Water with 0.01 Resolution, 0–14 Range and Automatic Calibration – Ruolan
A digital pH meter for water provides a portable way to monitor drinking water, pools, aquariums, hydroponic solutions and RO systems. This Ruolan tester displays pH across a 0.00–14.00 range with 0.01 resolution, helping users observe changes more precisely than broad-range color paper.
The pocket-size meter arrives pre-calibrated and supports an automatic calibration sequence using the included 6.86, 4.00 and 9.18 buffer powders. To measure, rinse the probe, immerse it below the indicated level, stir gently and wait for the value to stabilize. Automatic temperature compensation is listed from 0–80°C. One- and two-item options appear in yellow, red and blue configurations. The glass electrode is fragile: do not strike or touch it, avoid strong acids, strong alkalis and water above 50°C, then rinse and protect the probe after use.
