Hanna Instruments-98193 Professional Waterproof Dissolved Oxygen and BOD Meter
When measuring dissolved oxygen, compensations for salinity, temperature and pressure are essential to improve the accuracy and precision of readings.
Salinity compensation allows for direct determination of dissolved oxygen in saline waters. Temperature compensation is automatic with the probes built-in sensor, which features a one or two-point calibration. Pressure compensation with the meter's built-in barometer can be validated against a reference barometer, and if needed, can be recalibrated in user-selectable units (mmHg, inHg, atm, psi, kPa, mbar). With the internal barometer, the Hanna Instruments-98193 is able to compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information.
Other features include measurement, methods and calculations for BOD, OUR and SOUR.
