Features:
- Uses low-resistance general-purpose glass across the 0 to 14 pH range.
- Connects through a detachable VP8 cable interface without an internal preamplifier.
- Combines a double-junction reference, porous PTFE junction and integral solution ground.
The suffix identifies a no-preamp pH sensor rather than an ORP or preamplified execution.
Its electrochemical cell develops the measurement voltage interpreted by the remote analyzer.
Cable cleanliness, analyzer impedance and process mounting determine successful replacement.

- Water and wastewater systems can monitor basin, pipe or sample-stream pH.
- Neutralization and chemical-treatment skids use the sensor for continuous reagent-control feedback.
- General process vessels can apply insertion or submersion mounting through the supported NPT connections.
- The no-preamp output requires a compatible high-impedance pH analyzer input.
- A VP8 interconnecting cable is selected separately for the required installation length.
- Process mounting must use the supported 3/4 in. or 1 in. NPT arrangement.
- The general-purpose glass covers the documented 0 to 14 pH measurement range.
- Low-resistance glass supports response in colder aqueous samples down to the stated limit.
- The integral solution ground supports analyzer diagnostics where the connected transmitter provides them.
- Routine cleaning removes process coating from the glass and porous PTFE junction.
- Two-point buffer calibration evaluates slope and offset after cleaning.
- A dry, uncontaminated VP8 connection protects the high-impedance measurement path.
