➡️ Recommended Installation
➡️ Although sensors can be mounted directly in the main recirculation line, CHEMTROL® recommends installing in a Flow Cell Assembly (FCA) or weatherproof Sensor Cell Cabinet for:
Improved accuracy and stability
Easier servicing and calibration
Added protection from environmental wear
⚠️ Tech Tips & Cautions
⚠️ Always calibrate sensor per CHEMTROL® controller instructions for accurate readings
⚠️ Use in conjunction with CHEMTROL® controllers (such as CH250, PC2100, or PC6000) for automated water chemistry control
⚠️ Inspect cable regularly for wear; ensure watertight connections
⚠️ Replace sensor if readings become unstable despite calibration
