Description
xOverview
The ORAPXI pH Meter Salinity Tester is a compact, handheld tool designed for saltwater enthusiasts who want clearer visibility into evolving tank conditions. Whether you’re maintaining a reef, a koi pond, or a saltwater pool, this device collects critical readings in one glance, helping you respond quickly and confidently without guesswork.
Salinity stability matters for many marine inhabitants. The upgraded salinity sensor supports staying within the commonly recommended 33–35 ppt band, making it easier to observe when adjustments may be needed. When paired with precise pH readings, you gain a more complete view of your water chemistry and how it may influence activity, coloration, and growth in your system.
Calibration and reliability are built in. A calibration solution of 56.2 mS/cm (35.0 ppt) is included to help reset the baseline, keeping measurements meaningful across sessions and across different water types. This attention to calibration helps ensure readings remain consistent as you test during routine maintenance or after water changes.
Simultaneous, backlit display
The backlit LCD shows pH, salinity, TDS/EC, and temperature at the same time, so you don’t need to toggle modes. This streamlined display supports quick checks during routine maintenance, water changes, or whenever you’re inspecting a new tank setup.
With multi-parameter capability, you can monitor pH, salinity, TDS, EC, and temperature in one device. This versatility makes ORAPXI suitable for reef tanks, saltwater aquariums, swimming pools, hot tubs, spas, hydroponics, and even basic drinking-water checks, depending on your testing needs.
