It is based on state-of-the-art light absorption technology which provides very precise and stable readings in the single ppbw levels in High Purity Water and other Clean Water applications. Designed for maximum reliability and minimum maintenance, the analyzer requires no consumable electrolytes or membranes, and has no moving parts to wear out. The only maintenance required is the replacement of a UV lamp once every few years. Key technical advantages include extreme sensitivity, drift-free stability, and immunity to cross-interference from non-ozone gases. The dFFOZ-TR analyzer system includes a MINISCI-N Controller that features an alphanumeric LCD display, 4-20 mA and 0-10 VDC Opto-isolated analog signal outputs, 3 user programmable DPDT relays, RS-232 digital interface and a button to ZERO the sensor very easily at any time. A turnkey plug and play installation panel configured with pressure gauges, regulators and flow meter is also available as an option. Applications: Measure Traces of Ozone Dissolved in water Ultrapure Water Systems USP Water Systems Post Ozone Injection Post UV Radiation Other Applications Industries: Semiconductor Pharmaceutical Biotechnology Research Laboratories Other Industrial Processes Features: Sensitive to Traces of Ozone in Water in the PPB levels Patented Light-Absorption Measuring Technology No Consumable Electrolytes or Membranes No Moving Parts or Routine Maintenance Highly Stable Measurement Immune to Cross Interferences Analog and Digital Interface Convenient Unattended Operation
