Membran Sensors FC2, TC3, CD7, OZ7
Engineering summary from PDF text extraction for Membran Sensors FC2, TC3, CD7, OZ7. Verify every value with the OEM datasheet.
Summary
Product Identification
Wallace & Tiernan® membrane sensor measuring modules are available for:
- Free Chlorine (FC2)
- Total Chlorine (TC3)
- Chlorine Dioxide (CD7)
- Ozone (OZ7)
These are compatible with SFC and MFC electronics and various flow cell modules.
Benefits of Membrane Sensors
- Safe, long-term stable measurement system
- Integral temperature compensation
- No reagents required
Benefits of FC2 for Free Chlorine
- Continuous, on-line measurement of free chlorine even at high pH (up to pH 10) and low conductivity (from 10 μS/cm).
- Ideal for samples with varying pH due to internal buffering.
Typical Applications
- Measurement and control in industrial and municipal water treatment.
- Process measurement, final inspections, and neutralization plants.
- Monitoring of potable water, well water, pool water, and boiler feed water.
