Product Description

Digital aquaculture dissolved oxygen meter for water online optical do meter probe oxygen ppm meter


When it comes to measuring dissolved oxygen (DO) in water, there are several types of meters available. Here are some commonly used dissolved oxygen meters for water:


Handheld Portable Meters: These meters are compact, portable devices that allow for on-site measurements of dissolved oxygen in water. They typically feature a digital display, probe or sensor, and may have additional features such as temperature compensation, data logging, and calibration capabilities.


Optical DO Meters: Optical dissolved oxygen meters use luminescence-based technology to measure DO levels in water. They employ a probe or sensor containing a fluorescent or phosphorescent dye that reacts with oxygen. The meter measures the intensity of the emitted light, which is then used to determine the dissolved oxygen concentration.


Continuous Online Monitors: These monitors are designed for continuous monitoring of dissolved oxygen in water, such as in aquaculture systems, wastewater treatment plants, and environmental monitoring. They consist of a probe or sensor that is installed directly in the water system, providing real-time measurements and monitoring capabilities.


When selecting a dissolved oxygen meter for water, consider factors such as the measurement range, accuracy, response time, calibration requirements, maintenance, and the specific needs of your application. Additionally, ensure that the meter you choose is suitable for the type of water you are measuring, as water conditions and parameters can vary. Follow the manufacturer's instructions for proper operation, calibration, and maintenance to obtain accurate and reliable measurements.
