The common characteristics of these epoxy body, glass body and graphite body pH electrodes are:

  • Superior Stability - thanks to the special manufacture's knowledge
  • Fast response
  • Minimum sodium (alkaline) error
  • pH 0 -14 full range measurement
  • Special internal fill offers full range linear temperature compensation
  • Very low sensor glass membrane resistance
  • Zero and Isopotential: ~pH 7
  • Unique designed electrodes fit almost all kinds of pH meter
  • Ag/AgCl reference electrode
  • Ceramic Junction
  • Temperature Range: 0 -100 ˚C for glass body; 0-80 ˚C for epoxy and graphite body
  • Dimension: 12 x115 mm exclude cap
