Benchtop Dissolved Oxygen Meter

The DOB21 is a compact benchtop dissolved oxygen meter and a amperometric dissolved oxygen probe with automatic temperature compensation for field or laboratory applications. The unit measures dissolved oxygen in ppm or percent saturation and temperature in degrees Celsius. It features a RS232 output, auto calibration for all parameters, salinity and barometric pressure compensation, and data logging up to 99 points. Programming is conveniently done via a three button keypad and stored in the non-volatile memory. The unit also includes an audible minimum and maximum alarm. This product is ideal for testing biological samples, water and waste water, as well as aquariums. The DOB21 kit is supplied with the dissolved oxygen probe, a cell maintenance kit, BOD kit and operator’s manual all in a hard carrying case.
