Product description:
- 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
- This dissolved oxygen meter has two measurement units: % and mg/L.
- 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.
Calibration:
One-point calibration or two-point calibration, any point calibration
One-point calibration: (satisfying normal use) 0.0% (oxygen-free water) or 100.0% (air).
Two-point calibration: 0.0% (oxygen-free water) and 100.0% (air) calibration at the same timeThe instrument calibration is simple, make sure the probe is installed correctly before calibration:
1. 100.0%-After the value is stable in the air when the device is turned on, perform calibration. Press and hold the CAL. button for 5 seconds to release the button. The screen flashes 100.0%. After the flashing is completed, the calibration is completed.
2. 0.0%-After the value is stable in the anaerobic water under the power-on state, calibrate, press and hold the CAL. button for 5 seconds to release the button, the screen flashes 0.0%, the flashing is completed, the calibration is completed.
