Questions before purchase? Contact support →Listed parameters
Units explain the parameter, not an accuracy, range or safety claim. Compare with the unit and temperature reference shown by your exact device.
| pH | Acidity / alkalinity | pH |
|---|---|---|
| Free available chlorine | Listed chlorine reading | Check against a suitable reference test |
| ORP | Oxidation–reduction potential | mV |
| Salinity | Salt-related reading | Compare using the same unit reference |
| TDS | Total dissolved solids estimate | ppm / device-specific scale |
| EC | Electrical conductivity | µS/cm or mS/cm |
| Specific gravity | Density relative to a reference | SG / temperature reference matters |
| Water temperature | Temperature of the water | °C / °F display reference |
No dissolved oxygen. LoRa is the sensor link; WiFi is required for app connectivity.
Use the units and reference on your exact model. No ammonia, nitrite or nitrate measurements; not a drinking-water safety test.

No dissolved oxygen. LoRa is the sensor link; WiFi is required for app connectivity.
Resources / your exact model
Place the floating probe, position and power the display, then pair the display with 2.4 GHz WiFi and complete the supplied calibration process.
Open model-specific support →Use the model-specific calibration sequence and supplied materials. Do not apply another model’s targets or sequence.
Open the matching guide →Check placement, units and recent calibration. Follow model-specific cleaning, handling and storage guidance.
Open model-specific support →Questions, answered
No. LoRa is the floating probe → display link. The display → app link uses 2.4 GHz WiFi and Tuya.
No. Its eight listed readings are pH, free available chlorine, ORP, salinity, TDS, EC, specific gravity and water temperature.
No. ORP describes oxidation–reduction potential; it is not a chlorine or dissolved oxygen concentration. Use appropriate reference tests.
These specifications are not established in the available public documentation. Contact support for model-specific information rather than assuming a number.
Check sensor placement, unit/temperature reference and model-specific calibration. Share your model, photos, readings and recent calibration information with support.
