HI98140 is a portable Calibration Check pH meter that utilizes HANNA's SMART electrode technology.

SMART electrodes incorporate a chip, which stores the calibration data performed with a specific instrument. When the "SMART" electrode is attached to the meter again, it is automatically recognized. This allows the operator to optimize time and efficiency with unsurpassed safety. It also avoids erroneous measurements taken in the event the pH electrode is substituted after calibration.

Hanna Instruments Portable pH Meter with SMART Electrode Questions & Answers

  • What is the suggested pH range for my hydroponic system and soil plants?
    Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
  • My pH meter doesn't hold calibration. How often should I recalibrate it?
    pH meters do need to be calibrated by the user every day since the membrane does change and is affected by the temperature as well. If pH values are very critical then it will need to be recalibrated several times a day, or before each sample test (depending on how critical the value is). Uncontaminated calibration solution is very important as well. For each calibration, pour some solution in a separate container. Keep out of sunlight and away from heat.
