The DOB-343 model has been discontinued. Please see the DOH-SD1 as a possible alternative or contact our Flow Engineering Department.
The model DOB-343 benchtop meter provides both saturation and concentration measurement of dissolved oxygen levels. The respective measuring ranges are 0-199.9% and 0-19.9 ppm. The sensor is a MacKareth type, and replacement capsules are easily installed. Automatic temperature compensation is provided by a thermistor located in the oxygen probe. Calibration is achieved by one adjustment made at any temperature which sets both percentage saturation and concentration readings. A recorder output is standard to facilitate recordkeeping. The DOB-343 comes complete with probe assembly, sensor capsule, stirrer bar, guard shield and ac power adaptor. An optional temperature probe is available for making temperature measurements. (Meter reads in °C only.)
