The HI 98186 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. Salinity
compensation in water allows direct determination of dissolved oxygen in
saline waters. With its internal barometer, the instrument is able to automati-
cally 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).
HI 98186’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.
Remove the instrument from the packing material and examine it carefully to
make sure that no damage has occurred during shipping. If there is any
damage, notify your Dealer or the nearest Hanna Customer Service Center.
Each instrument is supplied with:
• HI 76407/4F Polarographic probe with built-in temperature sensors and
4 m (13.4”) cable
• HI 76407A Membrane cap (2 pcs)
• HI 7041S Electrolyte solution (30 mL)
• 4 x 1.2V AA, 1300 mAh Rechargeable Batteries (inside the instrument)
• HI 710042 Inductive Recharger with power adaptor
• Instruction Manual
• Rugged carrying case
Note: Save all packing material until you are sure that the instrument
functions correctly. All defective items must be returned in the original
packing with the supplied accessories.
