The product

With the OilGuard PR 30 from Sigrist, even the smallest traces of oil are reliably detected by means of sensitive UV fluorescence. In industrial processes, the OilGuard PR 30 serves power plants and the machine and metal sector.

How the OilGuard PR 30 works

The probe is factory-calibrated with the international standard 16 EPA-PAH. Recalibration is carried out with a solid reference.

Applications

The simple form factor enables a variety of installation options:

  • Immersed
  • In-line
  • By-pass

Sigrist thus offers a solution for almost all requirements.

Key features

  • Measurement of oil traces directly in water, fast and reliable
  • Easy recalibration with solid state reference without using wet chemistry in the field
  • Flexible installation possibilities due to simple form factor

Alutal, Sigrist’s exclusive distributor in Brazil for the Water and Industrial Processes segments, would be pleased to show you the possible applications on site or assist you with your projects, providing competent advice and local support in the practical use and service of the OilGuard PR 30.
