pH Sensor
The YuzhaLink pH Sensor tracks acidity continuously in aquariums, sumps, fish rooms and aquaculture systems, so pH becomes a trend you can read rather than a number you happen to catch on the day you…
Highlights
No controller, no cable run
Acquisition, signal processing and Wi-Fi live in the module, so the sensor reports to YuzhaLink on its own. There is no central controller to wire back to and no long probe cable to route from the water to the cabinet.
Put it where the water is
The only siting requirements are Wi-Fi coverage and a 5 V DC supply within reach. That frees the probe to sit in the display tank, the sump or a broodstock vat, rather than wherever the wiring happened to end.
Trends, not spot checks
Continuous logging turns pH from a single reading taken at test time into a curve. Drift you would never catch with a test kit becomes visible, which is what makes a water change or a dosing adjustment defensible.
Full 0–14 range at 0.01 pH resolution
The measuring range covers the whole pH scale and displays to 0.01 pH, across an operating range of 0–60 ℃ — enough resolution to see a drift developing rather than only its consequences.
Wet end and dry end, clearly separated
The electrode joins the module through an SMA connector: the probe goes in the water, the electronics stay out of it. The warranty is written the same way — an electrode immersed as instructed is not treated as water ingress.
Calibration is planned for, not improvised
pH calibration solution ships in the box along with a USB Type-C cable and a 5 V low-ripple adapter, so the first calibration can happen before the probe ever goes in.

The YuzhaLink pH Sensor tracks acidity continuously in aquariums, sumps, fish rooms and aquaculture systems, so pH becomes a trend you can read rather than a number you happen to catch on the day you test. That history is what turns water changes, dosing adjustments and early warnings into decisions backed by data.
Conventional pH probes terminate at a central controller, which means running signal cable from wherever the water is back to wherever the controller lives. This one does not. Data acquisition, signal processing and Wi-Fi are built into the module itself, so the only things it needs are a 5 V DC supply within reach and a completed Wi-Fi setup. Readings then travel to YuzhaLink wirelessly — no controller in between, and no long probe cable to route through the cabinet.
The product comes in two parts joined by an SMA connector: the pH electrode and the Wi-Fi acquisition module. The electrode can be fully immersed, and at minimum its sensing tip must be completely submerged. The module, the USB Type-C power input and every other electronic part stay out of the water and dry — that division is the one installation rule that matters. Measuring range is 0–14 pH with a display resolution of 0.01 pH, across an operating range of 0–60 ℃.
Calibrate the electrode before first use and periodically afterwards, following the product instructions. How often depends on water quality, temperature, how fouled the electrode becomes and how long it runs continuously. Recalibrate when readings drift, when response slows, or when a check against standard buffer solutions shows a clear offset. Calibration solution is included, along with a USB Type-C cable and a 5 V low-ripple power adapter.
Warranty is 12 months, and it draws the distinction that actually matters for a probe: an electrode immersed in the water it is measuring, as instructed, does not count as water ingress.
