DW-104A Benchtop Dissolved Oxygen Analyzer

Features

• New intelligent electrode management: The meter automatically recognizes high‑precision smart electrodes and retrieves the latest calibration data from the electrode chip to enhance data integrity and reduce operational errors.

• Intuitive user interface: A 7 inch full view LCD display with menu driven navigation simplifies operation. Automatic range switching is available during measurement.

• IP54 water resistant rating (performance subject to instrument, electrode and connection configuration). The instrument housing resists water splashes and may be cleaned with a damp cloth.

• High operational flexibility: An electrode holder is fitted on the right‑hand side of the instrument for convenient handling. The redesigned holder supports one‑handed vertical height adjustment to position the electrode optimally for reliable measurements and lowers risks of sample container tipping or electrode damage.

• Simple operation: One touch access to measurement, calibration and storage functions.

• Compatibility: Supports both standard dissolved oxygen electrodes and specialized trace

• DO electrodes with consistent high quality performance. Ergonomic design ensures comfortable handling.
