Introducing the DO9100 Waterproof Oxygen Concentration Meter, a marvel of precision engineering, offering a measurement range of 0.0-40.0 Mg/L. This digital water tester stands as a pinnacle of accuracy in the realm of dissolved oxygen and temperature measurement. Powered by an advanced microcomputer processor, it intelligently calculates and compensates for all relevant data, ensuring unrivaled precision. Encased in a robust, IP67-rated waterproof shell, this instrument is crafted for both durability and reliability across diverse environments. The DO9100 caters to various requirements with dual measurement units: % and mg/L. Its state-of-the-art probe is equipped with a film featuring a cutting-edge polarographic sensor and thermistor, delivering precise temperature measurement and compensation. The permeable film acts as a selective barrier, expertly allowing oxygen to react and be measured with remarkable accuracy, while separating the solution from the sensing electrode.
Measuring Range: Oxygen concentration (mg/L): 0.0-40.0 mg/L; Dissolved oxygen saturation (%): 0.0-300.0%. Temperature: 0-40°C (32-104°F). Resolution: Oxygen concentration (mg/L): 0.1 mg/L; Dissolved oxygen saturation (%): 0.1%. Temperature: 0.1°C (0.1°F). Accuracy: Oxygen concentration (mg/L): ±1.5% F.S.; Dissolved oxygen saturation (%): ±1.5% F.S.; Temperature: ±0.5°C. Calibration Mode: Supports both single-point and dual-point automatic calibration, with options for zero point or automatic 100% calibration in air. Response Time: ≤45s, ensuring fast response at 20°C. Temperature Compensation: Advanced ATC (0-50°C). Battery Power: Features a low-battery warning for timely replacement. Height Compensation: None. Automatic Shut Down: Powers down after approximately 15 minutes of inactivity. Power Supply: Operates on 3*1.5V button batteries (not included). Suitable Use Environment: 0-40°C (32-104°F); RH max 90%. Dimensions and Weight: 183*37*37mm (7.2*1.5*1.5in)/80g, compact and lightweight for ease of use.

Installation Instructions
Calibration: Select between one-point or two-point calibration for optimal results. For standard applications, one-point calibration suffices: 0.0% (oxygen-free water) or 100.0% (air). For enhanced precision, opt for two-point calibration, conducting both 0.0% (oxygen-free water) and 100.0% (air) calibrations. The calibration process is simple: ensure the probe is correctly installed before starting. 1. 100.0% Calibration - Activate the device, allow the value to stabilize in the air, then initiate calibration. Press and hold the CAL button for 5 seconds, release, and the screen will flash 100.0%, indicating success. 2. 0.0% Calibration - Similarly, in anaerobic water, with the device powered on, calibrate by pressing and holding the CAL button for 5 seconds, then release. The screen will flash 0.0%, confirming successful calibration.
