All the instruments are factory calibrated for temperature.
Hanna Instruments’s temperature probes are interchangeable and no temperature calibration
is needed when they are replaced.
If the temperature measurements are inaccurate, temperature recalibration should be performed.
For an accurate recalibration, please contact your local Hanna Instruments Office or follow the
instructions below.
Press “

It is better to perform a 2 point calibration.
The calibration can be performed in any two points that have at least 25 °C
distance between. It is
recommended that the first point be near 0 °C and the second point near 50 °C.
• Prepare a vessel containing ice and water and another one containing hot water (at approximately
50 °C or 122 °F). Place insulation material around the vessels to minimize temperature changes.
• Use a calibrated thermometer with a resolution of 0.1 °C as a reference thermometer. Connect the
HI763123
EC probe with built in temperature sensor to the appropriate socket.
• Immerse the
HI763123
probe into the vessel with ice and water as close as possible to the reference
thermometer. Allow a few seconds for the probe to stabilize.
• Use the
/
keys to set the calibration point value to that of ice and water mixture, measured
by the reference thermometer. Set the calibration point value to that measured in the reference
thermometer.
