Model DOB-343 benchtop meter provides both saturation and concentration measurements of dissolved oxygen. 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 record keeping. The DOB-343 comes complete with probe assembly, sensor capsule, stirrer bar, guard shield and ac power adaptor. An optional temperature probe enables temperature measurements from
-100 to 200 °C.
