Online PPb level dissolved oxygen analyzer

Product Introduction:

HD-RY100A online dissolved oxygen analyzer is a newly developed online monitoring precision instrument based on Clark electrode technology designed for measuring trace oxygen concentration in water/gas. The detection accuracy can reach ppb level. It is mainly used for online real-time monitoring and analysis of low-concentration dissolved oxygen such as deoxygenated water in power plants and waste heat boilers; the product complies with the national standard "GB/T 12157-2022 Determination of dissolved oxygen in industrial circulating cooling water and boiler water".

Product features:

High-resolution color touch screen: 480×272 graphic dot matrix, Chinese menu, easy to operate;

Real-time curve display: real-time digital and curve display measurement results, intuitive and convenient;

Single/dual channel setting: can connect 1 or 2 dissolved oxygen sensors, saving costs for customers;

Plug-in sensor: sensor plug-in design, easy maintenance;

High precision and high sensitivity: detection limit up to 0.10ug/L, resolution of 0.01ug/L;

Fast response and measurement: generally only 3 minutes from oxygen concentration in the air to ugL concentration;

Long-life electrode: long service life of the electrode, reducing the cost of frequent replacement of electrodes;

Long maintenance cycle and low-cost consumables: normal use 6~8 months electrode maintenance, simple and convenient;

Large-capacity data storage: can Store 700,000 data, historical curve query function;
