Install the instrument in a clean, dry, well-ventilated location without vibration. Ensure no corrosive gases are present in the surrounding environment.

The unit is designed for wall-mounted installation. Secure screws to the wall according to the instrument's mounting hole positions, then firmly install the unit.

The electrode must be installed in the constant flow electrode seat hole of the constant flow device, ensuring continuous water flow and complete electrode immersion. For extended periods without water flow, remove the sensor and cover with the original rubber sheath containing protective liquid.

1. Electrode Removal: Carefully push the electrode rubber sleeve with your fingernail (avoid twisting by hand to prevent damage) until fully removed. Preserve the rubber sleeve and protective liquid for temporary installations.
2. Electrode Installation: Insert the electrode into the constant flow device hole (near water outlet). Protect the glass head on the sensor top. Apply thread seal tape for waterproof sealing before installation.
3. Flow Requirements: Maintain constant flow rate of measured media. Recommended water flow: 15-30 cm³/s.
