Description
Automatic calibration: The high-measurement precision tester is equipped with 0% and 100% 2-point automatic calibration buttons, with simple calibration procedures convenient for calibration.
Ideal design: The dissolved oxygen measurement can be divided into two parts, the sensor and the electronic unit, and the electrode can be removed and replaced.
Temperature compensation: The temperature compensation function automatically recognizes and converts the corresponding value under the difference between the actual temperature of the solution and the standard temperature.
High Quality: Dissolved Oxygen Meter made of ABS, uses thin-film dissolved oxygen electrodes, and the electronic unit is an integrated operating amplifier + microcomputer chip.
Wide application: Dissolved oxygen digital pen, mainly used in agriculture and aquaculture, water treatment, and also a good helper for domestic fish.

How to use:
1. Rinse the electrode with deionized water or rinsing solution.
Press On/Off to turn on the machine. Immerse the electrode in the zero-oxygen solution for at least 3 minutes and hold it gently shaken 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 DO display value is 0% and the completion is zero. Calibration.
