Product Description
The YR01840 Online Dissolved Oxygen Controller is an advanced device designed to provide precise measurements and control of dissolved oxygen levels in various water samples. This machine is built for seamless integration into laboratory environments that demand high accuracy and reliability. Equipped with a polarographic electrode, this controller operates within a measuring range of (0 ~ 20.00) mg/L (ppm) and (0 ~ 200.0)% with a resolution of 0.1/0.01 mg/L (ppm) and 1/0.1%. Its accuracy is notable, with the electrode sensitivity being ±0.10 mg/L and the overall meter accuracy standing at ±0.40 mg/L.
One of the standout features of the YR01840 is its rapid response time, achieving 90% response in less than 30 seconds at 25ºC. This device offers automatic compensation for temperature, salinity, and pressure, ensuring unbiased measurements in various conditions ranging from 0 to 45ºC (temperature) and 0 to 45 ppt (salinity). The inbuilt auto-calibration system allows for “air saturated by water” or “water saturated by air” calibration, enhancing user convenience and consistency in performance.
