Description
The KROHNE SMARTPAT PH 8320 is a glass pH sensor for water and wastewater. It uses a PTFE diaphragm, integrated Pt1000 temperature element and built-in two-wire 4–20 mA/HART 7 transmitter for direct connection to a compatible control system.

Engineering selection checklist
| Measurement duty | Normal, minimum and maximum value; control, monitoring or compliance objective |
|---|---|
| Process conditions | Medium chemistry, conductivity, temperature, pressure, solids and coating tendency |
| Installation | Inline, flow-through or immersion assembly; connection, insertion length and maintenance access |
| Electrical interface | Loop power, 4–20 mA scaling, HART host compatibility, cable and hazardous-area needs |
| Order validation | Confirm sensor version, materials, approvals, assembly and accessories in the current KROHNE documents |
Industry application guidance
Use in suitable surface-water, process-water and wastewater loops after reviewing sample conductivity, solids, oil and coating. The selected flow, insertion or immersion assembly must keep the sensor wetted and representative while still allowing calibration and cleaning.
