Connect the tester to the Hanna Lab App and follow the calibration procedure.
See the App Help section for the calibration procedure.
10. SUSHI RICE MEASUREMENT
The application specific electrode design allows for
direct measurement of sushi rice
and
measurement of rice slurries
.
Preparation
• Calibrate the tester prior to measurement. Refer to calibration section for details.
• Loosen the threaded top collar counterclockwise before removing the probe from storage cap.
After measurement, place the probe tip into the cap and gently tighten the threaded collar.
• Do not be alarmed if salt deposits or storage solution are present. Rinse the electrode with purified water.
• If the glass and / or junction are dry, soak the electrode in Storage solution (or pH 4.01 or pH 7.01 buffer solution)
for a minimum of 30 minutes.
• After conditioning, rinse with water and blot dry.
