9092 Free Chlorine Analyzer
Range: 0-1000µg/L(ppb)
Range: 0-10mg/L(ppm)
The Waltron 9092 Free Chlorine Analyzer delivers automatic, continuous measurement of free chlorine, active chlorine, ozone, chlorine dioxide and bromine in clean water applications. Measurement is based on a highly-accurate electro-chemical process. The 9092 is used for industrial process monitoring and process control of free chlorine in feed water, drinking water treatment, cooling water treatment, water management in swimming pools, or the residual concentration Cl2 of chlorine-treated clear waste water. The potentiostatic technology allows for a much faster response time than membrane or amperometric systems, ensuring short start-up times, easy operation, and low maintenance.
- Wide range analysis: 0-1 mg/L (ppm), 0-10 mg/L (ppm)
- Automatic temperature and flow compensation
- Fast response time (t90 = 30 sec)
- No zero point adjustment required
- Withstands pressures up to 8 bar (116 psi)
- Analog and digital interface; data logging option
- Process calibration
- Minimal maintenance required
- Automatic pH compensation for free chlorine reading
