Product Description

Aquaculture Handheld digital dissolved oxygen meter professional do meter price


Here are some key features and considerations when using a portable dissolved oxygen meter:


Measurement Units: DO meters can measure dissolved oxygen in different units, such as milligrams per liter (mg/L) or parts per million (ppm).


Measurement Range: The meter should have a measurement range suitable for your specific application. Different models may have varying ranges, so ensure that the meter you choose covers the required range for your samples.


Accuracy and Precision: Look for a meter with high accuracy and precision to obtain reliable and consistent measurements. The specifications provided by the manufacturer should indicate the instrument's accuracy and repeatability.


Calibration: Regular calibration is essential to maintain the accuracy of the meter. Most portable DO meters allow calibration using air-saturated water or a calibration solution with a known DO concentration.


Temperature Compensation: Dissolved oxygen measurements are influenced by temperature, so it is important to have a meter with temperature compensation capabilities. This feature adjusts the readings based on the sample's temperature, providing more accurate results.


Probe Maintenance: The probe or sensor of the DO meter may require periodic cleaning and maintenance to ensure optimal performance and longevity. Follow the manufacturer's instructions for proper care and maintenance of the probe.


Data Logging: Some advanced portable DO meters offer data logging capabilities, allowing you to store and retrieve measurement data for further analysis and documentation.


Portability and Durability: Consider the portability and durability of the meter, especially if you need to use it in different locations or field settings. Look for models that are compact, lightweight, and have a rugged construction suitable for your specific application environment.


Power Source: Check the power requirements of the meter. Some models use replaceable batteries, while others have rechargeable batteries. Ensure that the power source meets your needs and that the battery life is sufficient for your intended usage.


Additional Features: Depending on your requirements, you may find additional features useful, such as a backlit display for low-light conditions, waterproof or submersible capabilities, or compatibility with external accessories like data transfer cables or printers.
