Hi everyone, I’m Kassandra and today we will be talking about how to calibrate your
edge multi parameter meter.
Perfect for lab use, this advanced meter measures 3 different parameters - pH, EC/TDS, and DO
simply by changing the sensor.
In this video, we’ll go through the calibration process for each parameter.
Hanna Instruments provides you with affordable and accurate equipment to help you achieve
professional results.
Calibration is an important step to ensure your meter is working to it’s peak performance.
We recommend calibration before each use.
To Calibrate pH, first be sure your edge® pH Electrode is plugged into the meter and
rinse it with deionized water.
Pour your hanna buffers into separate beakers and Press the CAL button to enter calibration
mode.
We recommend doing a 3 point calibration with the standard 4.01, 7.01, and 10.01 buffers.
By default, the meter asks for pH 7.01 buffer first.
Use the arrow keys to move the first calibration point to pH 4.01.
Then, place the electrode into your buffer.
Once stable, press confirm and the meter will ask you for your second calibration point,
pH 7.01.
Rinse the electrode with deionized water, and place it into the buffer.
Again, once stable, press confirm.
Rinse the electrode again and place it into your pH 10.01 buffer.
Once you have calibrated your 3 points, press the CAL button to save calibration and return
to measurement mode.
For EC/TDS Calibration, plug the Hanna HI763100 EC/Temperature Electrode into the meter.
For accurate calibration and to minimize cross-contamination, use two beakers for the calibration standard;
one for rinsing the probe and one for calibration.
Use plastic beakers to minimize any EMC interferences.
Press CAL to enter calibration mode.
Then, rinse the electrode in your first beaker with your standard, then submerge it into
the second beaker for calibration.
It’s best to use a magnetic stirrer for the most accurate readings.
The sleeve holes must be completely submersed.
The recognized standard value will automatically appear on the display.
Once stable, press confirm and the calibration will save and the meter will return to measurement
mode.
To perform a 100% dissolved oxygen calibration, Rinse your HI764080 polarized probe with clean
water and then dry the tip.
Suspend the probe just over a beaker of water and press CAL.
When the reading is stable and is within the limits, press confirm.
The meter will display WAIT and 0.0 % will be displayed in lower right corner.
Press CAL to calibrate to one point and exit calibration; To continue with a 0% Dissolved
oxygen calibration, Submerge the probe into a beaker containing HI 7040 Zero Oxygen solution
and stir gently for 2-3 minutes as the reading goes down.
Be sure the temperature sensor is covered.
When the reading is stable and stops decreasing, press confirm and the meter will automatically
return to measurement mode.
Rinse the probe tip off in water before taking measurements in samples.
So that’s it.
The edge multi parameter meter is perfect for business and educational lab use.
Available in 3 different configurations, It’s versatility and advanced technology set the
standard for benchtop meters.
