Product Description

Accurate atc Dissolved Oxygen Meter Sensor Aquarium Dissolved Oxygen Sensor DO Meter Digital


A digital dissolved oxygen (DO) meter is a handheld device used for measuring the amount of dissolved oxygen in a liquid, typically water. It is widely used in various industries, including aquaculture, wastewater treatment, environmental monitoring, and research applications.


Here are some key features and considerations when looking for a digital dissolved oxygen meter:


Measurement Principle: There are different measurement principles used in digital DO meters, including Clark, Galvanic, Polarographic, and Optical. Each principle has its advantages and limitations, so choose a meter based on your specific needs and the target application.


Probe Type: Select a meter that comes with a suitable probe for your intended use. Probes can be polarographic or optical. Polarographic probes use a membrane and require periodic maintenance, while optical probes do not have a membrane and are generally easier to maintain and clean.


Measurement Range: Consider the range of dissolved oxygen levels you need to measure for your specific application. Ensure that the meter has a suitable measurement range that covers your required values.


Accuracy and Precision: Look for a meter that provides accurate and precise measurements. Check the specifications and user reviews to understand the meter's accuracy level and ensure it meets your requirements.


Calibration: Most digital DO meters require regular calibration to maintain accuracy. Choose a meter that offers easy calibration options, preferably with automatic calibration features or clear step-by-step instructions.


Display and User Interface: Ensure that the meter has a clear and easy-to-read display, even in different lighting conditions. The user interface should be intuitive and user-friendly, allowing for easy operation and access to essential settings and functions.


Data Storage and Connectivity: Some meters offer data storage capabilities, allowing you to store and retrieve measurements for further analysis. Connectivity options, such as USB or Bluetooth, can facilitate data transfer to other devices or software for data management and processing.


Battery Life: Consider the battery life of the meter, especially if you need to use it for extended periods without access to power. Longer battery life can minimize disruptions during field measurements.


Durability and Portability: Look for a meter that is robust, designed to withstand harsh environments, and easy to transport. Consider factors like waterproof or water-resistant features, shock resistance, and overall build quality.


Price: Compare prices among different brands and models, considering the features, quality, and support offered. Balance your budget with the required performance and reliability needed for your specific application.


By considering these factors, you can choose a digital dissolved oxygen meter that best suits your needs and provides accurate and reliable measurements of dissolved oxygen levels in liquids.
