HI6421 DO Meter Hanna Instrument and HI6421P are streamlined benchtop meters with a large touch screen display, comprised of a housing and an integrated module designed for fresh and saltwater measurements of dissolved oxygen.

Advanced Dissolved Oxygen DO Meter Hanna Instrument with Optical DO Probe (opdo®)

DO Meter Hanna Instrument HI6421 includes Hanna’s HI7641133 optical dissolved oxygen probe (opdo^®) that is based on the principle of fluorescence quenching. An immobilized Pt-based luminophore is excited by the light of a blue LED and emits a red light. As oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence. The lifetime of the luminescence is measured by a photodetector and is used to calculate the dissolved oxygen concentration.

The probe is fitted with easy to use Smart Caps (HI764113-1) which lock in place and contain pre-loaded calibration coefficients that are automatically transmitted to the probe. The Smart Cap features an immobilized O₂ sensitive luminophore with rugged insoluble black oxygen permeable protective layer.

Over time, the sensor’s optical components can age but are compensated for by using the reference signal to compensate the measuring path. As a result, the sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.

Advanced DO Meter Hanna Instrument with Polarographic DO Probe

HI6421P includes the HI764833 polarographic probe. Slim and versatile, this probe covers a wide range of dissolved oxygen and has a built-in thermistor temperature sensor that compensates for temperature variations. The slim design allows for convenient measurement in test tubes and Biological Oxygen Demand (BOD) bottles.

Durable and robust, the probe features a platinum cathode and Ag/AgCl anode assembly. Accurate and with a fast response time, readings are not flow dependent.

The probe is fitted with durable (PTFE), oxygen permeable, screw on membrane caps. Caps are filled with electrolyte and easily installed on the probe.

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.

Pressure compensation is done automatically (built-in barometer) or users have the option to manually enter required value. Pressure is displayed in user-configurable units: mmHg, mbar, kPa, inHg, psi, atm.

User Interface

7-inch capacitive touch screen with multi-touch support
Capacitive touch back, home and system menu keys
User-friendly icons and symbols allow users to easily navigate and interpret the instrument functions.

Five Intuitive Views

Basic measurement configuration
Simple GLP with calibration information
Full GLP with electrode status and calibration point details
Live updated, interactive graph
Tabulated data with date, time, and notes

Measurement

Application-specific profiles allow quick and direct measurement without the need to update the sensor and system settings
Active log during measurement
Measurement stability indicator (using the Stability Criteria setting)
Reading modes: direct and direct/autohold
Temperature compensation can be automatic or set manually
Audible and/or alarm messages for measurements outside of predefined limits
Galvanic isolation for measurement

Calibration

One or two points calibration at 0% and/or 100% saturation
Single point manual calibration in mg/L or % saturation using a reference method
Non-volatile memory saves data and settings

Zero Oxygen Calibration Solution

When performing a DO calibration, it is important that the correct standards are used. We include some starter solution to get you going. HI7040L is a bi-component zero oxygen solution designed so you can quickly calibrate to 0% oxygen concentration.

Logging

Data log collection of up to 1,000,000 data points (with time and date stamp)
Logging types: manual, automatic, autohold
Sample ID for manual and autohold data
