Comet series

Stable oxygen sensing, ideal for measurements in pure gas streams

Our Comet series of sensors delivers a single source of low-level oxygen (O2) measurements, from purity applications to sub-parts-per-million (ppm) readings, for OEM customers.

Using high-stability Coulometric technology, they respond rapidly to changing sample conditions or flow rates, making them ideal for upset-prone applications.

Three versions of this RoHS 2 compliant series are available:

  • Comet Certo for O2 measurements in the range 0-10,000ppm
  • Comet Elite for O2 measurements in the range 0-1,000ppm
  • Comet Premus for O2 measurements in the range 0-100ppm

An oxygen sensor for a wide range of measurements

With three models available, each covering a different measurement range, the Comet series offers stable, accurate O2 sensing for purity applications and other applications that require sub-ppm readings.

Perfect for measuring in pure gas streams, typical applications for the Comet include solder reflow ovens, annealing furnaces, glove boxes and gas bottling.

Sensors for industrial, medical and specialist OEM customers

The Comet sensor series offers measurement stability and integration flexibility to an extensive range of applications. Whatever your Market sector, we have the knowledge to guide you to the best solution for the gas sensing you need.
