Specification Brand : Topyond BulletPoint1 : Automatic Calibration Buttons: The dissolved oxygen meter is equipped with 0% and 99% 2-point automatic calibration buttons, providing convenience for calibration. This feature allows for quick and accurate calibration of the instrument. BulletPoint2 : Temperature Compensation Function: The meter includes a temperature compensation function that automatically recognizes and converts corresponding values based on the difference between the actual solution temperature and the standard temperature. This ensures accurate measurements by accounting for temperature variations. BulletPoint3 : Modular Design: The instrument can be divided into two parts - the sensor and the electronic unit. Additionally, the electrode can be removed and replaced, offering flexibility and ease of maintenance. BulletPoint4 : Sensor and Electronic Unit Technology: The sensor utilizes thin-film dissolved oxygen electrodes, while the electronic unit is integrated with an operational amplifier and a microcomputer chip. This technological combination enhances the precision and reliability of the dissolved oxygen measurements. BulletPoint5 : Applications: The meter is primarily used in agriculture and aquaculture, as well as in water treatment processes. It also serves as a valuable tool for monitoring and maintaining proper oxygen levels in household pet fish environments.

Rinse the electrode with deionized water or rinse solution. Press On/Off to turn on the machine. Immerse the electrode in the 0-oxygen solution for at least 3 minutes and keep shaking gently until the displayed value is stable. 2. Press the on/off key until the second line of the "CAL" character is displayed, and gently shake the electrode. When the displayed value is stable, press the "%/L/mg" key, the display DO value is 0%, and the completion is 0.
