  • Stability icon. Take the reading when the smiley face stays on screen. 
  • Icons for finished calibrations  
  • Simultaneous temperature display
• LabSen 861: Powered by sensor technologies and key materials from Switzerland, LabSen 861 pH Electrode, which is built with LabSen's most robust PHY glass membrane and anti-clogging PTFE junction along with a Silver-ion-trap reference system, making reliable pH measurement of high-temperature liquid and caustic solutions easier than ever.
• Special PHY membrane: The special PHY membrane is highly resistant to chemical corrosions, maximizing the reliability and service life of the electrode in complex and high-temp. solution testing.
• PTFE Ring Junction: The PTFE ring junction prevents junction clogs from complex chemicals.
• Silver-ion-trap reference system: The combination of a Long-life reference system and a silver ion trap. The silver ion trap will absorb all the exuded Ag+, ensuring that there's no Ag+ in the reference electrolyte, and avoiding junction clogs caused by samples containing sulfides, proteins or TRIS buffer solutions.
