Kuntze is a manufacturer for sensors and complete measuring systems. We are developing and producing pH electrodes since the 1950s – and since 2013 in our modern production facility in Hartha / Germany. As a manufacturer with a high vertical integration, we offer our customers the complete set of modularity in the electrode construction.

Multifunctional Glass

• AH / High alkali high temperature glass
  Measuring range pH 0.. 14. Very small alkaline error. Suitable for temperatures up to 135°C (275°F), depending on reference electrolyte.
• LT / Low resistance glass
  Fast sensor response time due to minimized resistance. Measuring range pH 0..12 at temperatures ranging from -5° to +60°C (23° to 140°F).
• SF / Fluoride-resistant glass
  Tolerates up to 500 mg/l of fluoride over a measuring range of pH 1.. 11. Maximum temperature 60°C (140°F).

Junction

• Zircon junction
  The Allrounder - Low electrolyte leakage with maintenance friendly gel-electrolyte. For low conductivity water with refillable electrolyte, or for special applications in process control with protruding junction (can be ground down or covered).
• Platinum junction or glass cut
  For ultrapure water with very low conductivity - Twisted platinum thread for high electrolyte leakage, or ground glass joint for adjustable leakage. Alternatively with 3 Zirkon junctions for fixed leakage.
• Teflon junction or no junction at all
  Robust and dirt resistant - Teflon junction with large surface area. For heavily contaminated water, open hole junction in combination with hydrolysis-resistant solid electrolyte.

Connection

• S8 plug
  Two-poles S8 plug with rotatable, colored PG 13.5 thread.
• Variopin plug
  Electrodes with integrated temperature sensor (Pt100 or Pt1000) have a variopin plug with PG13.5 thread (not rotatable).
• Fixed Cable
  Alternatively, our electrodes can also be delivered with fixed cable, e.g. with BNC, DIN plug or free cable ends.
