Using edge
®
blu
1. To begin using the HALO
®
probe, turn on the edge blu. The meter will start scanning for probes.
2. Press the operation button located on the top of the probe. The blue LED halo will begin to flash every half
second, indicating it’s in discoverable mode. The probe ID will appear in the probes list.
3. Select your probe from the probes list and press
CFM
. Whilst connecting, the blue LED will flash 4 times
per second. Once connected, it will slow down and flash every 2 seconds.
MEASUREMENT SETUP
1. Calibrate the pH probe.
2. Take measurements using the pH probe.
3. When probe is not in use, place the clear protective cap over glass bulb.
MEASUREMENT GUIDES
1. Always clamp or support the probe during use.
2. Frequent calibrations are suggested for critical pH applications.
3. To eliminate thermal or sample gradients, stir buffers and samples using a magnetic stirrer.
CALIBRATION
1. Calibration can be performed using up to five calibration buffers. For accurate measurements, a minimum
of a three-point calibration is recommended.
2. Enter calibration screen (using Hanna Lab App or edge blu).
3. Place the probe in the first buffer.
4. Confirm the calibration point when the reading is stable.
5. Repeat the procedure for up to five calibration points. For details, please see edge blu instruction manual
or Hanna Lab App “HELP” section.
STORAGE
1. Rinse off the
FC2142
HALO probe with deionized water to remove sample.
2. Blot off using a soft tissue.
3. Pour 1 cm of
HI70300
storage solution into the clear protective cap. Place probe bulb into the cap.
