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.)
