PAROX 2000Plus, the new paramagnetic oxygen analyser from MBE AG

The new PAROX 2000Plus, a simple, accurate, cost effective paramagnetic oxygen analyser, equipped with auto calibration and RS232 interface by default, can even become a multi-component analyser by adding NDIR units for carbon monoxide, carbon dioxide or methane. Thus, a wide field of application in ambient, emission and process gas measurements is open, for example, biogas, sewer gas, landfill gas, gases from fermentation processes, toxicity and lower explosion limits.

The PAROX 2000Plus is a precise oxygen analyser for continuous monitoring purposes based on the paramagnetic measuring principle (partial pressure measurement with rotatable glass dumbbell). The paramagnetic sensor unit itself is thermostat temperature controlled at 55°C; measuring ranges from 0 – 5 Vol.% O₂ up to 95 – 100 Vol.% O₂ are available (analog output: 4 – 20 mA or 0 – 20 mA). When combined with NDIR units for CO (typically 0 – 10 Vol.%),  for CO₂ (typically 0.2 to 100 Vol.%) and/or for CH₄ (typically 10 to 100 Vol.%), a multi-component analyser is ready to use.

The instrument is microprocessor controlled with self-diagnosis capability; it is operated by means of a user friendly key pad and a 16-digit LCD display. In addition, the analyser can also be controlled via the RS232 interface (USB or D-Sub).

The programmable auto calibration function together with the integrated relays allow a fully automatic calibration by connecting appropriate zero and span gas. An internal flow regulator, the basis of accurate measurements, guarantees a small and constant flow through the O₂ measuring cell while a constant flow between 10 and 90 l/h of measuring or calibration gas is applied at the inlet of the analyser. If an electronic flow sensor is installed, the incoming flow can be monitored and will be displayed together with the concentration value. Furthermore two different alarm relays can be set for supervising the measured concentration.

As to case dimensions, the PAROX analyser is available in 19” rack or table version, as half 19” portable instrument or in a wall-mounted housing.
