pH Pack   Home / SmartQ Sensors  

This pack contains both the pH adaptor and the pH electrode to form the immensely popular pH sensor

The Smart Q pH sensor has both a pre-set calibration range (so the sensor is ready for immediate use in Chemistry or Biology) and a user calibration range.

Titration in action with ph sensor
Chemistry:
  • Testing acids and alkalis
  • Acid-Base titrations
  • Acid rain
Environment:
  • Water quality
 

Biology
Biology:
  • Dissolved Oxygen in water
  • Enzyme action
  • Cell respiration
  • Human respiration
  • Photosynthesis and respiration
 
 
The Sensor has two ranges:
  • The Default calibration - the stored pre-set calibration suitable for most experiments.
  • The User calibration – the calibration can be adjusted using the Sensor Config application in the EasySense software to take into account different temperatures (above or below 25°C) or deterioration of an electrode.

Maintain the level of storage solution, the pH sensitive glass membrane must be kept wet. Store the electrode tip in a 1:1 solution of pH 4 buffer and 3.5 to 4 mol dm-3 KCl
