Introduction
pH Meter features precise measurement capabilities for both pH and dissolved oxygen levels across a range of aqueous solutions. Its integrated chip facilitates automatic calibration and temperature compensation, enhancing the tester's reliability. Real-time monitoring through a smart electrode status display further ensures accuracy. With a quick polarization time of 3-5 minutes, dissolved oxygen measurements are both rapid and precise. Additionally, smart data storage and communication functionalities add further value to the product.
Applications
pH Meter is widely used across water treatment plants, aquaculture, food and beverages, environmental testing, pharmaceuticals, research, and development.
