OZ-150W Water Ozone Analyzer for Sterilization and Oxidation Process Monitoring
The OZ-150W Dissolved Ozone Analyzer is a high-precision instrument designed for the analysis and detection of dissolved ozone concentration in pure water and semiconductor industries. Utilizing dual-path UV absorption technology, it offers accurate and reliable measurements with a detection range of 0-300ppm (customizable ranges: 0-50ppm, 0-100ppm, 0-200ppm). Equipped with a patented UV light source auto-adjustment system, the OZ-150W ensures long-term stability by automatically calibrating the UV LED brightness based on reference light data, maintaining consistent zero-point accuracy. Featuring long-life imported UV LED technology, this analyzer supports 24/7 continuous operation, making it ideal for industrial applications requiring uninterrupted monitoring. With its robust design and advanced functionality, the OZ-150W guarantees precise and stable ozone concentration detection, setting a new standard for reliability in water quality analysis.
Test method: dual-path ultraviolet absorption method, long-life light source system, high measurement accuracy. Measurement principle: Based on the Lambert-Beer law, accurate measurement is performed through the principle of photometric absorption.
Measurement range: 0-50ppm; 0-100ppm; 0-200ppm; 0-300ppm Light source system: foreign long-life ultraviolet light source system (wavelength 253.7nm).
Usage: Indoor installation and use, equipped with power supply and signal terminals.
Light pool system: Separate light pool technology, no leakage, high pressure resistance, and resistance to large flow sampling gas impact.
Intelligent compensation: with automatic adjustment of zero point, with automatic light source compensation function.
Operation method: Users can choose manual zeroing and automatic zeroing according to the operating status, and can set the automatic zeroing time.
Display unit: mg/L, ppm optional.
Data display: high-definition color touch screen. Output function: 4-20mA, RS485 communication, two sets of alarm point output, etc.
Automatic zero adjustment: It can adjust the brightness of the UV LED light source in real time according to the reference light data to keep the zero point data constant and ensure the stability of the zero point.
Multiple versions: OZ-150W is used for pure water, and OZ-150W-HF can be used for 20% hy acid ozone aqueous solution.
