Introducing the Do9100 Digital Dissolved Oxygen Meter, a marvel of modern technology designed specifically for aquatic environments. This state-of-the-art device operates within a remarkable range of 0.0-40.0 Mg/L, offering supreme precision and dependability. Equipped with an advanced microcomputer processor, it effortlessly calculates and compensates for every bit of measurement data, promising unrivaled accuracy. Wrapped in a sturdy waterproof casing rated IP67, the DO9100 is built to withstand diverse conditions. With its dual measurement capabilities in both % and mg/L, it caters to a wide spectrum of requirements. The innovative probe, paired with a cutting-edge polarographic sensor and thermistor, ensures impeccable temperature measurement and compensation. The permeable film acts as a selective gateway, facilitating a precise oxygen reaction, while elegantly isolating the solution from the sensing electrode for accurate measurements.
Measuring Range: Oxygen concentration ranges from 0.0 to 40.0 mg/L, with dissolved oxygen saturation spanning 0.0-300.0%, and temperature coverage from 0 to 40°C (32-104°F). Resolution is finely tuned at 0.1 mg/L for oxygen concentration, 0.1% for oxygen saturation, and 0.1°C (0.1°F) for temperature. Accuracy is maintained at ±1.5% F.S. for both oxygen concentration and saturation, and an impeccable ±0.5°C for temperature. The DO9100 supports flexible calibration modes, including single or dual-point automatic calibration with zero or automatic 100% air calibration. It boasts a swift response time of ≤45s at 20°C and offers ATC temperature compensation from 0-50°C. Features low-battery warnings, automatic shutdown after approximately 15 minutes, and operates on 3*1.5V button batteries (not included). Designed for environments ranging from 0-40°C (32-104°F) with 90% max RH. Compact dimensions are 183*37*37mm (7.2*1.5*1.5in) and a lightweight 80g.

Installation Instructions
Calibration: For unparalleled precision, choose between one-point or two-point calibration. A one-point calibration suffices for standard use at 0.0% (oxygen-free water) or 100.0% (air). For ultimate accuracy, embark on a two-point calibration journey, performing both 0.0% and 100.0% calibrations concurrently. Calibration is intuitive: ensure the probe is properly installed before beginning. 1. For 100.0% calibration, with the device active and stabilized in air, press and hold the CAL button for 5 seconds, then release. The screen flashes 100.0%, signaling success. 2. For 0.0% calibration in anaerobic water, with the device powered on, press and hold the CAL button for 5 seconds, then release. The screen flashes 0.0% to confirm successful calibration.
