A Pocket Dissolved Oxygen (DO) Tester is a portable and handheld device designed to measure the concentration of dissolved oxygen in water. It is commonly used in various industries and applications, such as environmental monitoring, aquaculture, wastewater treatment, and scientific research.
The main components of a typical pocket dissolved oxygen tester include:
Sensor Probe: The sensor probe is the essential part of the tester responsible for detecting and measuring the dissolved oxygen in the water. It usually employs an electrochemical or optical sensor technology.
Display: The tester features a built-in digital display that shows the dissolved oxygen concentration in the water. The display can be in the form of an LCD or LED screen, providing clear and easy-to-read results.
Buttons/Controls: The device has user-friendly buttons or controls that allow you to operate the tester, calibrate the sensor, and navigate through its settings and features.
Calibration Function: Dissolved oxygen sensors require periodic calibration to ensure accurate readings. The pocket DO tester usually comes with a calibration function, allowing you to calibrate the device using standard calibration solutions.
Battery: It is powered by batteries (often rechargeable) to make it portable and suitable for field use.
Protective Cap: Some models have a protective cap for the sensor probe, which helps keep the sensor clean and protected when not in use.
