The OMEGA™ DOH-SD1 is innovative and easy to operate. What sets the DOH-SD1 apart from other dissolved oxygen meters is that it incorporates a real-time SD card data logger. The DOH-SD1 measures dissolved oxygen and has adjustments for altitude and salt. Download data from the SD card into an Excel spreadsheet. This allows the user to do further data or graphical analysis without special software. The DOH-SD1 has a wide variety of applications from water conditioning, aquariums, and fish hatcheries to food processing, educational and other laboratories.

Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic 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.
Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter
