Monitors oxygen in the beverage production process
The Orbisphere M1100 optical sensor, together with the Orbisphere 410 one channel and the Orbisphere 510 multichannel controller, offers a new way of monitoring oxygen in the beverage production process.
Minimal Drift and Annual Calibration
The M1100 sensor provides immediate oxygen readings with a measurement frequency of two seconds. The instrument carries consistent readings with no drift for 12 months without calibration (when utilising standard weekly CIP processes), surpassing other optical sensors that display significant drift after only a few months in similar conditions.
Minimal Maintenance Optical Technology
The M1100 pioneered the use of luminescent technology in brewing applications and as a result, the sensor doesn’t require the replacement of membranes or any electrolytes. Additionally, the sensor’s accuracy is unaffected by process changes or pressure shocks, further reducing maintenance.
Annual maintenance is limited to just a few minutes for a zero-point calibration. Chemicals are not required for this process, making the task easier and safer without reducing measurement precision.
Low Level Oxygen Measurement with Accurate ppb
The M1100-L sensor has a lower detection level of 0.6 ppb. This highly accurate instrument’s readings are essential to control low oxygen levels in beverage production. As an example, it is critical to control low level oxygen in the post fermentation applications of the brewery to ensure high quality of the final product.
High Level Oxygen Measurement with Accurate ppm
The M1100-H sensor has a range of 0-40 ppm, and is ideal for use in wort applications, for example. Even in this harsh wort environment, the instrument maintains very good accuracy and minimal drift. Only a yearly maintenance and calibration will be required in most cases.
