Measuring range:

1.DO9100 is a precision meter for measuring dissolved oxygen and temperature. The built-in microcomputer processor can calculate and compensate all measurement data related to dissolved oxygen and temperature. The shell of this instrument is waterproof, and the waterproof grade: IP67
2.2. This dissolved oxygen meter has two measurement units: % and mg/L.
3.The dissolved oxygen probe is a film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable film separates the measured solution from the sensing electrode, but allows oxygen to pass through the film to react , The solubility can be measured.

How to use and correct the procedure:

1.CAL calibration key (long press 5 seconds to enter the calibration interface)

2.HOLD lock/hold key, Fahrenheit/Celsius temperature conversion key.

3.DO9100 pen-type intelligent dissolved oxygen analyzer (hereinafter referred to as the instrument) is mainly designed to facilitate the user to carry on-site operation. The instrument can be divided into two parts: sensor and electronic unit. The sensor uses a polarographic film-type dissolved oxygen electrode. The electronic unit is composed of high integrated circuits. The instrument uses a dot-matrix liquid crystal display to display dissolved oxygen values and temperatures.
