Continuous analyzer for the measurement of dissolved oxygen in liquids or the presence of oxygen in gases. Specially designed for low range measurement.

  • Especially suitable for beers, deaerated water and carbonated beverages.
  • High-performance optical sensor measurement system installed directly in the Varivent© housing.
  • Measuring principle: Optical sensor, integrated in the instrument.

OXYTRANS TR is a high-precision optical oxygen sensor for the measurement of O₂ in liquids and gases. A typical application is the measurement of oxygen in boiler feed water and in protective atmospheres.

  • Optical technology; no need for electrolyte and membrane changes
  • Short response time and excellent long-term stability.
  • Applicable for a wide range of concentrations and temperatures.
  • Highly accurate and virtually maintenance-free.
  • Various flange connections available
  • Hygienic execution and full CIP capability

*New OXYTRANS ATEX: High-precision optical oxygen sensor, developed for use in potentially explosive environments.
