Dissolved oxygen analyzer MARK-303M
Dissolved oxygen analyzer MARK-303M. The analyzer is designed to measure the mass concentration of oxygen dissolved in water (DOC), the level of liquid saturation with oxygen saturation (OSO) and the temperature of aqueous media. It is used for measurements of biochemical oxygen demand (BOD) in accordance with methods that allow the use of the amperometric method of measuring KKD. The device can measure the concentration of dissolved oxygen at a depth of up to 20 meters. The scope of application of the analyzer is for measuring the QKD, UK and temperature in surface and waste waters. It is used in fish farms, technological processes in the chemical, biotechnological, food industries, in educational processes, and in environmental sectors. Analyzer with external polarizing voltage and sensitive element. The device automatically adjusts temperature and barocompensation and adjusts the air oxygen level. The compact, sealed analyzer is reliably protected from dust and moisture. MARK-303M stores records of up to 500 groups of measurements in named folders. Ability to create and manage a data archive on a PC. All values are displayed on a backlit LCD graphic indicator. Up to 600 hours of continuous operation on AA batteries. Features: Convenience and accuracy of measurement. Electronic notepad. USB port and software. Backlit graphic indicator. Easy air calibration. Storing the sensor in air. Long lasting sensor. Low power consumption. Basic kit: converter block, oxygen sensor with 5 meter cable, electrolyte, sensor spare parts kit, a set of chemical reagents for preparing a “zero” solution, set of elements type AA, USB cable.
