The BOD biochemical oxygen demand analyzer is based on the national standard "H1505-2009" 5-day cultivation method, simulating the biological hydrolysis process of organic matter in nature, and using a simple, safe, and reliable mercury free pressure difference sensing method to measure BOD in water; Fully intelligent design, leading R&D technology and design manufacturing, no need for laboratory personnel to be on duty during the experimental process; Suitable for biochemical oxygen demand measurement in the fields of polluting enterprises, environmental monitoring, sewage treatment plants, third-party testing institutions, scientific research, universities, etc.

Product Features of Yetuo YT-BOD50A BOD Biochemical Oxygen Demand Analyzer

Large size liquid product display screen, intuitive and clear, easy to select projects;

Can simultaneously measure six samples, six independent testing terminals, and add new measurement groups at any time during the testing process;

Directly read the B0D concentration value without calculation;

Mercury free pressure difference design, high accuracy, no conversion required, and ensuring the safety and health of experimental personnel;

There is no pipeline design in the experimental stage to avoid drawbacks such as pipeline aging and air leakage;

The measurement range can be selected, and no dilution is required when the water sample concentration is below 4000g/L;

The measuring instrument automatically records measurement data, with a selection of 60 sampling points per testing cycle for more accurate detection data;

The cultivation period can be adjusted and selected according to needs;

Automatically complete the measurement process without the need for dedicated personnel to be on duty;

The testing terminal comes with a large capacity battery, which can last for more than 2 years in standby mode and is not easily affected by short-term power outages in the external environment during the testing process;
