Please include the following in your inquiry

  • Medium and concentration (does it contain fluoride, chlorine or solid particles?)
  • Temperature range and pressure range
  • Cleanliness: scaling, crystallization, oil mist
  • Measuring range and control setpoint
  • Interface requirements: 4–20 mA / digital communication / interlock or not

Why we ask about the duty first

Take the same "pH measurement": a fluoride-bearing medium, high-purity water, 80 °C service and a solids-laden slurry need four different electrodes, and the price differs threefold. We ask first so that you do not buy the wrong one.

Response time

Normally we return a preliminary configuration proposal within 24 hours on business days;
complex duties need a process interview, typically 2–3 business days.
