Descrição

The DOB21 model has been discontinued. Please see the DOH-SD1 as a possible alternative or contact our Flow Engineering department.

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. 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. 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.
