Thank you for selecting a Hanna Instruments® product. Please read this instruction guide before using the HALO probe with the Hanna Lab App or with the HI2202 edge® blu pH  Bluetooth®  meter. For additional information on probe maintenance and calibration consult the Hanna Lab App “HELP” section or the edge blu instruction manual.
IMPORTANT! During servicing and measurement, handle the probe with care. Do not drop the probe on a hard surface. It will permanently damage the probe. Utilize the clear protective cap to protect and keep the pH bulb hydrated during transport and storage. Blue LED halo indicator
