The
HI98193
is a state of art, microprocessor based, dissolved oxygen instrument with many automated
and specific application features, designed to provide laboratory results and accuracy under harsh
industrial conditions.
All measurements are automatically compensated for temperature. Manual salinity compensation in
water allows direct determination of dissolved oxygen in saline waters. With its internal barometer,
the instrument is able to automatically compensate for changes in barometric pressure so there is no
need for charts, altitude information or external barometric pressure information.
The instrument contains built‑in application software for the calculation of Biochemical Oxygen
Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR).
HI98193
’s calibration has been greatly simplified when compared to other dissolved oxygen
instruments. It is provided with a series of new features which add entirely new dimensions to the
measurement of DO, by allowing the user to dramatically improve the reliability of the measurement:
• One or two points automatic dissolved oxygen calibration.
• One point manual dissolved oxygen calibration using a value in milligrams per liter or percent
saturation entered by the user.
• One or two points user temperature calibration.
• Messages on the graphic LCD for an easy and accurate calibration.
• User‑selectable “calibration time out” to remind when a new calibration is necessary.
Moreover, the meter offers an extended temperature range from ‑20.0 °C to 120.0 °C
(‑4.0 °F to 248.0 °F).
Other features include:
• Log on demand up to 400 samples.
• Auto Hold feature, to freeze first stable reading on the LCD.
• GLP feature, to view last calibration data.
• PC interface.
