Professional DO9100 Dissolved Oxygen Meter Backlight Digital DO Tester Water Quality Detector for Seawater Freshwater Fish Tank DO9100 is a precision meter for measuring dissolved oxygen and temperature. The built-in microcomputer processor can calculate and compensate all measurement data related to dissolved oxygen and temperature. The shell of this instrument is waterproof, and the waterproof grade: IP67

This dissolved oxygen meter has two measurement units: % and mg/L.

The dissolved oxygen probe is a film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable film separates the measured solution from the sensing electrode, but allows oxygen to pass through the film to react , The solubility can be measured. Specifications : 1.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
