Dissolved Oxygen Meter – Model: CDO-01 The Dissolved Oxygen Meter (Model: CDO-01) is a precision laboratory instrument designed for accurate measurement of Dissolved Oxygen (DO), Oxygen Saturation (%), and Temperature in water samples. The instrument utilizes the membrane electrode method with a polarographic dissolved oxygen electrode to provide fast, reliable, and highly accurate measurements. It is widely used in aquaculture, water treatment plants, environmental monitoring, beverage production, sewage treatment, biological agriculture, research laboratories, educational institutions, and quality control laboratories. The CONTECH Dissolved Oxygen Meter features a polarographic DO electrode that offers a short polarization time, quick response, and precise measurement performance. The instrument automatically compensates for temperature, salinity, and atmospheric pressure using the built-in air pressure sensor, ensuring highly accurate results under varying environmental conditions. The CDO-01 is equipped with a large backlit LCD display, real-time clock, memory storage for up to 100 test results, and data logging for up to 500 measurements with selectable logging intervals. The bidirectional RS-232 interface enables easy communication with computers and printers, allowing continuous or single printouts of measurement data. It also generates GLP-compliant calibration reports, making it suitable for laboratory documentation and quality assurance applications. The instrument features easy-to-use electrode calibration, a replaceable diaphragm cap, automatic salinity compensation, automatic air pressure correction, and automatic temperature compensation for dependable performance. Designed for long-term reliability and ease of operation, the CDO-01 is an ideal solution for routine laboratory testing, environmental analysis, industrial process monitoring, and scientific research.
