DO9100 Portable Dissolved Oxygen Analyzer/Meter with External DO Probe, ATC

This lot includes one (1) DO9100 Portable Dissolved Oxygen Analyzer, a compact pen-style meter designed for measuring dissolved oxygen in freshwater and saltwater applications. The built-in microcomputer processor calculates and compensates all measurement data related to dissolved oxygen and temperature. The meter features a polarographic DO sensor with a permeable membrane that separates the measured solution from the sensing electrode, allowing oxygen to diffuse through for accurate concentration measurement. Measurement ranges include dissolved oxygen concentration from 0.0 to 40.0 mg/L with 0.1 mg/L resolution, dissolved oxygen saturation from 0.0 to 300.0% with 0.1% resolution, and temperature from 0 to 40C (32-104F) with 0.1C resolution. Accuracy is +/-1.5% full scale for DO and +/-0.5C for temperature. Features automatic temperature compensation (ATC) from 0-50C, single-point or dual-point automatic calibration (zero point or 100% air calibration), backlit LCD display, data hold function, IP67 waterproof rating, and auto power-off after approximately 15 minutes. Compact pen-style design at 183 x 37 x 37 mm weighing approximately 80g. Suitable for aquaculture, hydroponics, swimming pools, water treatment, and laboratory applications. New in box.
