CE & ISO 9001:2015 certified manufacturer · Est. 2014 · 150,000+ installations · Greater Noida, India
Measures dissolved ozone concentration in water treatment process streams using electrochemical sensing. Dissolved ozone measurement is essential for verifying CT values required by WHO, CPCB, and EPA disinfection guidelines. Mounts directly in-line on ozone contact tank outlet providing real-time readings that feed back to ozone generator PLC for automatic dose control. Contactor support integrates monitor with ozone contact chamber for complete CT calculation and documentation. Essential for CPCB compliance documentation.

Frequently Asked Questions
Ozone India Technology dissolved ozone monitors use amperometric electrochemical sensors — a membrane-covered electrode generates a measurable current proportional to the dissolved ozone concentration in the sample water. Measurement range is 0–2 mg/L with ±0.02 mg/L accuracy at standard conditions.
Calibration is required quarterly per CPCB compliance documentation standards and before regulatory inspections. The Indigo Colorimetric Method (standard spectrophotometric reference) is used for calibration: collect a sample, add Indigo reagent, measure absorbance at 600nm, and compare to monitor reading. Adjust monitor calibration if deviation exceeds 10%.
Yes. The dissolved ozone monitor provides a 4–20 mA analog output proportional to dissolved ozone concentration, which can be wired to the ozone generator's modulating input to maintain a set dissolved ozone residual automatically. This closed-loop control prevents under- or over-dosing.
Response time (T90 — time to reach 90% of step change in reading) is 30–60 seconds for the membrane electrode sensor. This is fast enough for online process control in water treatment applications where dissolved ozone changes slowly.
