XF260E industrial pH sensor
PTFE or PEEK liquid-junction options were selected for corrosion resistance in the acidic, contaminated medium.
Verified customer project · Argentina
Online pH monitoring for acidic food-processing wastewater
The customer needed stable continuous pH measurement in acidic wastewater containing lemon oil, suspended solids and organic impurities. FUNEL configured an acid-resistant, anti-fouling measurement system and supported commissioning remotely.

01
The measurement challenge
Conventional glass sensors were prone to contamination and frequent maintenance in the customer’s acidic, high-fouling process.
- Acidic lemon-processing wastewater, typically pH 2–3
- Lemon oil, suspended solids and organic impurities
- High risk of sensor contamination and fouling
- Complex installation environment requiring stable continuous monitoring

Configured FUNEL solution
The measurement point was configured around the real medium, installation and integration requirements rather than the pH range alone.
PH5000 pH transmitter
Large LCD display for continuous local indication and project operation.
PTFE installation bracket
A chemically resistant mounting arrangement for reliable installation and maintenance access.
PT1000 temperature compensation
Temperature compensation was included for more accurate online measurement.

Remote commissioning solved a real wiring fault
The initial PT1000 connection produced an abnormal 83.9°C reading. FUNEL reviewed the wiring remotely, guided the terminal correction and helped return the temperature and pH display to normal operation.
