Detailed Product Description

Instrument to measure dissolved oxygen in water Dissolved oxygen measuring instrument

 

There are several types of instruments used for measuring dissolved oxygen (DO) in various applications. Here are some commonly used instruments:

 

Optical DO Probes: Optical dissolved oxygen probes use luminescence-based technology to measure DO. These probes typically contain a fluorescent or phosphorescent dye that reacts with oxygen. The intensity of the emitted light is inversely proportional to the dissolved oxygen concentration, allowing for measurement.

 

Membrane Electrode DO Meters: Membrane electrode DO meters employ a membrane-covered electrode that interacts with the dissolved oxygen in the sample. The oxygen diffuses through the membrane, generating a potential difference or current that is measured to determine the DO concentration.

 

Portable DO Meters: Portable DO meters combine a handheld device with a sensor or probe for on-site measurements. These meters often feature digital displays, user-friendly interfaces, temperature compensation, and calibration capabilities. They may use one of the above-mentioned measurement principles.

 

Online DO Sensors: Online DO sensors are designed for continuous monitoring of dissolved oxygen in industrial processes, wastewater treatment plants, and aquaculture systems. These sensors are installed directly in the system, allowing real-time monitoring and control.

 

When selecting a dissolved oxygen measuring instrument, consider factors such as measurement range, accuracy, response time, calibration requirements, maintenance, and the specific needs of your application. It is also important to follow the manufacturer's instructions for proper operation, calibration, and maintenance to obtain reliable and accurate measurements.

 

Product Description

The handheld device can be used for monitoring of dissolved oxygen, temperature and PH in water, and can meet the requirements of portable accurate water quality measurement.
