The GPro 500 oxygen sensors from Mettler Toledo combine in-situ sensor convenience with the power of an analyser.

The new oxygen sensors from Mettler Toledo offer exceptional measuring performance and easy installation, and require little or no maintenance. Tunable Diode Laser (TDL) gas analysers are a significant improvement over extractive analysis systems since no sample extraction or conditioning is necessary. TDL gas analysers are also immune to interference from moisture, dust or background gases in addition to exhibiting very low drift.

Mettler Toledo has combined TDL technology with their expertise in industrial application analytical instrument design to create a probe that delivers the convenience of an in-line sensor and the level of measurement confidence of a top line analyser.

Unlike other TDL gas solutions that have a cross-stack design causing installation difficulties and requiring regular, troublesome realignment, the GPro 500 oxygen sensors incorporate a probe that reflects the laser beam back to the receiver in the sensor head, eliminating the need for alignment. Since the laser beam travels twice through the gas stream, the optical path length is doubled, resulting in more accurate O2 measurement.

Mettler Toledo’s Intelligent Sensor Management (ISM) technology adds to the GPro 500 by incorporating predictive diagnostics that continually assess the optical path quality and indicate when cleaning is required, before measurements are affected. No maintenance is required other than yearly verification and occasional cleaning of the optics.

The GPro 500 oxygen sensors from Mettler Toledo provide real-time, continuous, accurate and faster O2 measurements with a significantly lower cost of ownership.
