Introducing the DO9100 Waterproof Oxygen Concentration Meter, a marvel of modern technology, expertly crafted to measure dissolved oxygen and temperature with unmatched precision. Featuring a sophisticated microcomputer processor, this device smartly calculates and compensates for all pertinent measurement data, delivering extraordinary accuracy. Constructed with a robust IP67-rated waterproof shell, this instrument is built to withstand diverse environments, ensuring both durability and reliability. The DO9100 offers versatile measurement units in both % and mg/L, adeptly meeting varied needs. Its state-of-the-art probe, equipped with a pioneering polarographic sensor and thermistor, facilitates precise temperature measurement and compensation. The permeable film acts as an effective selective barrier, enabling accurate oxygen interaction and measurement, simultaneously isolating the solution from the sensing electrode.
Measuring Range: Oxygen concentration ranges from 0.0 to 40.0 mg/L; Dissolved oxygen saturation spans 0.0 to 300.0%; Temperature spans 0-40°C (32-104°F). Resolution offers fine detail: Oxygen concentration at 0.1 mg/L; Dissolved oxygen saturation at 0.1%; Temperature precision at 0.1°C (0.1°F). Accuracy is assured: Oxygen concentration and dissolved oxygen saturation provide ±1.5% F.S.; Temperature holds to ±0.5°C. Calibration Mode supports either single-point or dual-point automatic calibration, including zero point or a 100% air calibration. Response Time is notably fast, at ≤45s at 20°C. Temperature Compensation is automatic (ATC 0-50°C). A low-battery warning ensures power considerations. Height Compensation is not required. The device automatically shuts down after about 15 minutes to conserve energy. Power is supplied by 3*1.5V button batteries (not included). The device thrives in use environments of 0-40°C (32-104°F) with RH max 90%. Its dimensions and weight are 183*37*37mm (7.2*1.5*1.5in) and 80g.

Installation Instructions
Calibration: Select between one-point or two-point calibration for optimum precision. Typically, one-point calibration suffices: 0.0% (oxygen-free water) or 100.0% (air). For enhanced precision, employ a two-point calibration: Conduct both 0.0% (oxygen-free water) and 100.0% (air) calibrations concurrently. Calibration is simple-ensure the probe is properly installed before commencing. 1. For 100.0% calibration - Once powered, when the value stabilizes in air, start calibration. Hold the CAL button for 5 seconds, then release. The display will flash 100.0%, confirming successful calibration. 2. For 0.0% calibration - Similarly, in oxygen-free water with the device on, press and hold the CAL button for 5 seconds, then release. The display will flash 0.0% to confirm calibration success.
