Hanna opdo™ Optical Dissolved Oxygen Meter HI-98198 by Hanna

Hanna opdo™ Optical Dissolved Oxygen Meter HI-98198 Hanna

The HI-98198 opdo™ meter is a rugged, portable dedicated dissolved oxygen (DO) meter designed for fresh and saltwater measurements of dissolved oxygen. This professional, waterproof meter complies with IP67 standards.

This professional, waterproof meter complies with IP67 standards and measures DO, barometric pressure, and temperature.

The HI-98198 is supplied with a HI-764113 digital optical dissolved oxygen probe in a custom thermoformed durable carrying case with accessories. It is compact and ergonomically designed to provide ready access to the materials required for routine sampling.

The meter is supplied with:

  • HI-764113 Optical DO probe with built-in temperature sensor, protective shield and 4m (13’4) cable
  • HI-764113-1 Smart Cap™ with o-ring
  • HI-7040 Bicomponent Zero Oxygen Solution
  • Calibration/Storage vessel
  • 100ml plastic beaker (2 pcs)
  • 1 syringe with silicon grease
  • 1 lens wipe
  • 1.5V AA batteries (4 pk)
  • Instruction manual
  • Meter quality certificate
  • Probe quality certificate
  • Cap quality certificate
  • USB Type A to C cable
  • Carry case

Other features include:

  • Text messages on the graphic LCD display to warn and guide the user
  • Back lighted display
  • One or two points calibration at 0 or/and 100% saturation (with auto recognition)
  • A single point manual calibration in mg/L or % saturation using a reference method for calibration value
  • A dedicated HELP key for assistance anytime
  • A user selectable “calibration due” warning
  • A dedicated GLP key that includes the last 5 calibrations with time, date, calibration points, as well as barometric pressure, temperature and salinity setting
  • AutoEnd freezes the next stable measurement value on the display
  • Log on demand with 4000 records capability
  • USB-C port for easy data transfer to memory stick, PC or other compatible devices

The HI-98198 opdo™ is only compatible with the Hanna digital dissolved oxygen probe HI-764113.

Concentration measurements are automatically compensated for barometric pressure, temperature and salinity. Barometric pressure and temperature are automatically measured and compensated. Salinity is automatically compensated by setting manually the salinity concentration of the water being measured. The meter also has a built in application to measure and calculate BOD (biological Oxygen Demand), OUR (oxygen uptake rate), and SOUR (Specific Oxygen Update Rate).

How the probe works

The Hanna HI-764113 optical DO sensing probe is based on the principle of fluorescence quenching. The sensing method features an immobilised pT based luminophore that is excited by the light of a blue LED and emits a red light. Dissolved oxygen quenches this excitation.

The major components of the probe include a blue LED for excitation, a red LED that is used as a reference light, and a photodetector. The Smart Cap™ is locked in place on the optical probe and includes the immobilised 02 sensitive luminophore with rugged insoluble black oxygen permeable protective layer.

The sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.
