Portable pH meters, conductivity meters, and oxygen meters

This family of pH, conductivity, and oxygen meters are your ideal companion for routine use.

You can use the instrument as a portable meter or as a benchtop instrument in the laboratory.

Thanks to a large color display, a rugged design, and smart technology, these meters will make pH value and conductivity measurement as easy as never before.

These meters are available as:

  • pH meters
  • conductivity meters
  • combined oxygen meters
  • and combined meters.

Robust instruments: for mobile and laboratory use

These meters are ideal for use in the field …
  • Ergonomic design for single-hand use
  • Dust- and waterproof (IP67-rated)
  • Perform measurements for hours thanks to the powerful built-in lithium polymer battery
  • Recharge the battery using any 5 V USB power adapter or a 12 V socket in a car.
… and in the laboratory: Use the stand plate and mains power supply to convert the instrument into a benchtop meter.
