Trace level (ppb level) dissolved oxygen analyzer

Product Introduction:

The HD-RY100 handheld trace level (ppb level) dissolved oxygen analyzer is a precision instrument developed by Holder Electronics based on Clark electrode technology, specially designed for measuring trace oxygen concentration in water/air. The detection accuracy can reach ppb level. It is mainly used for the detection and analysis of low concentration dissolved oxygen such as deoxygenated water in power plants and waste heat boilers, as well as trace oxygen detection in semiconductor ultrapure water; 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-precision and sensitive sensor: detection limit of 0.1ug/L (ppb), resolution of 0.01ug/L (ppb);

Fast response and measurement: no preheating is required, sample pretreatment is not required, and the reaction is fast. Generally, it takes only 3 minutes from the saturated oxygen concentration in the air to the ug/L level concentration;

Multi-purpose: with gas oxygen and liquid dissolved oxygen detection and analysis functions (optional);

Easiest use and calibration: measurement can be performed after powering on, without long-term electrode polarization;

Long-life electrode: the service life of the electrode is more than 5 years, reducing the cost of frequent electrode replacement;

Long maintenance cycle and low-cost consumables: low maintenance, usually maintenance once every 6 months, self-maintenance, simple and convenient;

Low power control and long working time: dry battery powered, continuous working time exceeds 1200 hours;
