电极 pH电极
This general purpose combination electrode with toughened bulb and top-performance glass body can be used for precise pH determinations. Compared to conventional electrodes, the proven ROSS reference system exhibits superior stability in measurements, faster response, greater accuracy and precision when measuring samples that vary in temperature or when calibrating in temperatures that differ from the samples.

  • ROSS electrodes avoid the long term drift that other electrodes exhibit (ROSS electrodes drift by less than 0,002 pH per day), so recalibration is minimised
  • No sample contamination: ROSS electrodes do not contain any silver or mercury to react with the sample or to clog the electrode junction
  • Can be used in samples such as biological media, foodstuffs and pharmaceuticals where trace amount of metals cannot be tolerated
  • Double junction design allows more control over an important variable
  • In order to minimise errors caused by junction potential, users can use a solution that is similar to the sample
  • User also has the ability to change filling solutions to minimise contamination when potassium or chloride in the sample are undesirable
  • Reference system: Mercury-free, TRIS, protein and sulphide compatible
  • Waterproof BNC connector is compatible with any standard BNC connector
