2.2 Probe Installation
The probe offers three installation methods to suit different aquarium setups:
- Wall Clip: Attach the probe to the aquarium wall using the provided clip.
- Wall Suction: Use the suction cups to secure the probe to the inside of the aquarium glass.
- Floating Sponge: Insert the probe into the floating sponge to allow it to float on the water surface, adjusting automatically with water level changes.
Important Note: Do not submerge the entire probe in water. Submerge the probe only halfway into the water. Excessive water pressure can damage it and shorten its lifespan. Ensure the hollow probe cap is replaced before use.

3.2 Parameter Details
- pH: Measures the acidity or alkalinity of the water.
- Temperature: Displays water temperature in Celsius or Fahrenheit.
- TDS (Total Dissolved Solids): Indicates the concentration of dissolved substances in the water.
- EC (Electrical Conductivity): Measures the water's ability to conduct electricity, related to dissolved salts.
- Salinity: Measures the salt content of the water.
- SG (Specific Gravity): Indicates the density of the water relative to pure water, commonly used for saltwater.
- ORP (Oxidation-Reduction Potential): Measures the water's ability to break down contaminants.
3.3 Temperature Unit Switching
You can switch between Celsius (°C) and Fahrenheit (°F) temperature units directly from the Tuya Smart App settings.
3.4 Alerts and Notifications
The Tuya Smart App allows you to set custom alert ranges for each parameter. When a parameter goes out of range, you will receive instant notifications on your smartphone. Ensure notifications are enabled in the app's settings to receive these alerts.
3.5 Data Recording
The device automatically records real-time data for all parameters. This historical data can be viewed by day and month within the Tuya Smart App, allowing you to track trends and changes in your water quality over time.
4. Maintenance
4.1 Probe Care and Replacement
The platinum probe is designed for durability but requires regular cleaning and eventual replacement to maintain accuracy. Clean the probe gently with distilled water and a soft cloth. If readings become inconsistent or inaccurate after cleaning and calibration, the probe may need to be replaced.
4.2 Calibration
The monitor supports 3-point pH calibration. Use the provided pH calibration powders (pH 4.01, pH 6.86, pH 9.18) according to the instructions in the Tuya Smart App to ensure accurate pH readings. Regular calibration is essential for precise measurements.
5. Troubleshooting
If you encounter issues with your TEKCOPLUS TK504PLUS monitor, consider the following:
- No Power: Ensure the USB power cable is securely connected to both the monitor and a working power source.
- No Readings/Incorrect Readings: Verify the probe is correctly plugged into the main unit and submerged halfway in the water. Clean the probe and perform a pH calibration if necessary.
- WiFi Connection Issues: Ensure your WiFi network is 2.4GHz. Restart the monitor and your router. Re-attempt the WiFi pairing process through the Tuya Smart App. Check that the monitor is within 5 meters of the probe.
- App Not Receiving Alerts: Check the notification settings within the Tuya Smart App and your smartphone's operating system settings to ensure alerts are enabled.
