Electrode Probe Dissolved Oxygen Meter

Product Description

Dissolved Oxygen Monitoring System Optical Dissolved Oxygen Sensor Electrode Probe Dissolved Oxygen Meter


Here are some key features and components commonly found in portable dissolved oxygen meters:


Electrode or Sensor: The heart of the DO meter is the oxygen sensor or electrode. There are two main types of electrodes used in portable DO meters: polarographic and galvanic. Polarographic electrodes are more common and offer high accuracy, while galvanic electrodes are typically used for quick readings but may have a shorter lifespan.


Temperature Compensation: Many portable DO meters include a built-in temperature sensor or accept an external temperature probe. Temperature compensation is crucial because the solubility of oxygen in water varies with temperature.


Display: A digital display provides real-time readings of dissolved oxygen levels. It typically shows the DO value in units such as mg/L (milligrams per liter) or % saturation.


Calibration: Regular calibration is essential to maintain accuracy. Portable DO meters usually offer one or two-point calibration using standard solutions with known oxygen concentrations.


Data Logging: Some advanced models have data logging capabilities, allowing you to record measurements over time. This feature is valuable for tracking changes in oxygen levels.


Battery Power: Portable meters are powered by batteries, so consider the battery life and the availability of rechargeable batteries when choosing a meter for extended fieldwork.


Waterproof and Durability: Fieldwork often involves exposure to harsh conditions, so a rugged and waterproof design is essential for durability.


Portability: These meters are designed to be easily carried in the field, so they are typically compact and lightweight.


User Interface: A user-friendly interface with intuitive buttons or a touchscreen makes it easier to operate the meter in the field.


Accessories: Portable DO meters may come with accessories such as carrying cases, protective covers, and calibration solutions.
