Presenting the DO9100 Waterproof Oxygen Concentration Meter, a masterclass in precision and reliability, measuring dissolved oxygen and temperature across a remarkable range of 0.0-40.0 Mg/L. At the heart of its advanced design is a sophisticated microcomputer processor that astutely calculates and compensates for all measurement data, guaranteeing precision like never before. Encased in a durable, IP67-rated waterproof shell, this powerhouse of innovation is crafted to withstand diverse environments. The DO9100 is versatile with its dual measurement modes: % and mg/L, perfectly catering to varying user demands. Its state-of-the-art probe features a film with an avant-garde polarographic sensor and thermistor, delivering impeccable temperature measurement and compensation. The specially designed permeable film acts as a selective barrier, facilitating oxygen reaction and measurement with supreme accuracy, while adeptly isolating 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: Offers flexibility with single-point or dual-point automatic calibration, supporting zero point or full 100% air calibration. Response Time: Swift and efficient, ≤45s at 20°C. Temperature Compensation: Automatic (ATC) from 0-50°C. Battery Power: Features a low-battery alert. Height Compensation: Not applicable. Shut Down: Convenient automatic shutdown after approximately 15 minutes to save energy. Power Supply Mode: Operates on 3*1.5V button batteries (batteries not included). Use Environment: Designed for 0-40°C (32-104°F); with a relative humidity max of 90%. Dimensions and Weight: Compact and lightweight, measuring 183*37*37mm (7.2*1.5*1.5in) and weighing just 80g.

Installation Instructions
Calibration: Achieve optimal accuracy by selecting either one-point or two-point calibration. For standard use, one-point calibration is sufficient: either 0.0% (oxygen-free water) or 100.0% (air). For precise measurement, opt for two-point calibration, executing both 0.0% (oxygen-free water) and 100.0% (air) calibrations simultaneously. The process is user-friendly-ensure the probe is installed correctly before beginning. To calibrate at 100.0%, once the device is active and stabilizes in air, initiate calibration by pressing and holding the CAL button for 5 seconds, then release. The screen will flash 100.0%, confirming successful calibration. For 0.0%, in anaerobic water with the device on, calibrate by pressing and holding CAL for 5 seconds, then release. A flashing 0.0% on the screen confirms success.
