Digital Dissolved Oxygen DO Meter Professional Fish Aquarium Meter D09100

D09100 is a precision instrument for measuring dissolved oxygen and temperature. The built-in microcomputer processor calculates and compensates all the measurement data related to dissolved oxygen and temperature. The case of this instrument is waterproof. Dissolved oxygen meter (measurement unit): Percent saturation (%) or oxygen concentration (mg/L) The probe for dissolved oxygen is a film with a polarography sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode, but allows oxygen to pass through the membrane to react, and the concentration can be measured.
