1. Product Overview
The kactoily Upgraded 6 in 1 Aquarium Water Test Monitor provides real-time monitoring of six crucial water parameters: pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), Salinity, Specific Gravity (SG), and Temperature. Designed for both freshwater and saltwater environments, this device helps maintain a healthy aquatic ecosystem by providing accurate and simultaneous readings on its clear LCD display.
Its split design allows for easy probe replacement, and the platinum probes ensure a longer lifespan and more accurate detection, even when submerged.

The monitor features a compact display unit and a separate probe, allowing for flexible installation and continuous monitoring of your aquarium's water quality. It is suitable for various aquatic environments, including fish tanks and ponds.

4. Operating Instructions
The monitor provides continuous real-time readings of your aquarium's water parameters. The LCD display shows all six parameters simultaneously.

Display Readings: The main display shows Salinity (%), Specific Gravity (SG), pH, Temperature (°C), Total Dissolved Solids (TDS in ppm), and Electrical Conductivity (EC in us/cm). The backlight ensures clear visibility.
Calibration and Adjustment
Regular calibration ensures the accuracy of your measurements. The device supports manual calibration and adjustment.

pH Calibration: Use the provided pH buffer powders to calibrate the pH reading. Follow the on-screen instructions for pH-CAL-2 and pH-CAL-3. For precise adjustments, use the pH-Adj function.
EC Calibration: The device also allows for EC-set calibration.
Temperature Adjustment: If necessary, the temperature reading can be adjusted via the Temp-set option.
Refer to the on-screen menu for detailed steps on accessing these calibration and adjustment functions. The "Setting/Next" button navigates through options, and "Confirm" applies changes.
5. Maintenance
To ensure the longevity and accuracy of your kactoily Aquarium Water Test Monitor, regular maintenance is recommended:
- Probe Cleaning: Periodically clean the probe to prevent buildup of algae or mineral deposits, which can affect accuracy. Use a soft brush and distilled water.
- Calibration: Calibrate the device regularly, especially the pH sensor, using fresh buffer solutions. The frequency depends on usage and water conditions.
- Storage: When not in use for extended periods, ensure the probe is clean and stored in a suitable solution (e.g., KCL storage solution or pH 4 buffer) to keep the sensor hydrated.
- Cable Inspection: Check all cables and connections for any signs of wear or damage.
6. Troubleshooting
If you encounter issues with your monitor, try the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Probe dirty or needs calibration; sensor aging. | Clean the probe. Perform a full calibration using fresh buffer solutions. If issues persist, the probe may need replacement. |
| Display Not Turning On | Power cable disconnected; faulty power adapter. | Ensure all power connections are secure. Try a different USB charging cable or power adapter. |
| No Readings for a Parameter | Probe not fully submerged; damaged probe. | Ensure the probe is submerged past the minimum level. Inspect the probe for visible damage. |
If troubleshooting steps do not resolve the issue, please contact customer service.
