Digital LCD Displays PDO Portable Dissolved Oxygen Analyzer PDO1000 With PC Controller
1. Features and Benefits
•With innovative principle of the fluorescence method, no need to replace the diaphragm and the electrolyte, maintenance-free.
• no need to replace the fluorescent cap, lower operating costs.
• No oxygen consuming, neither require the flow rate nor agitation.
•Anti-interference of the chemical substances in the wastewater, can be used in harsh wastewater environment.
• Basically maintenance-free, saving time and reducing the cost of the owners.
• Factory pre-calibration
• No polarization requirement.
• Response quickly, only minimal amount of stirring needed.
• Measurement accuracy is able to reach 99% accuracy.
• Rugged sensor maintain its accuracy in the case of contamination or be scratched, easy to clean.
• With more than 5 years service life.
• Good performance at small range, more suitable for sewage treatment works application.
• Large storage space, and can read data through the USB interface directly.
