4. Installation Notes
The fluoride ion sensor supports immersion installation with a 3/4 NPT pipe thread, making it suitable for tanks, pipelines, reservoirs, and water quality monitoring stations. For best measurement stability, the sensor should be installed in a stable water flow area and protected from strong mechanical impact, sediment accumulation, and excessive cable tension.
For long-term use in water, seawater, or humid outdoor environments, all wiring joints should be waterproofed, and the user-side cable should have corrosion-resistant protection. Before powering on the sensor, check the wiring sequence carefully to avoid communication failure or electrical damage.
