METPOINT MCA
For mobile and flexible compressed air analysis
Continuous monitoring is essential to ensure consistent compressed air quality in your system. Nevertheless, it may be necessary to take measurements at points where no stationary measurement technology has yet been installed. For such cases, the METPOINT MCA (“Measuring Compressed Air”) offers a mobile and flexible solution.
Oil measuring range
≤ 0.01 to 2.5 mg/m³
Pressure range
3 to 16 bar
Particles
from 0.1 μm (option P)
Display
7-inch touch
To detect vaporous and gaseous hydrocarbons in compressed air applications, the METPOINT MCA measures the residual oil vapour content. It can detect residual oil content down to thousandths of a mg/m³ during operation. Thanks to short measuring intervals, even the smallest changes are detected quickly and reliably. This means you can monitor the residual oil content of your compressed air at all quality-relevant points in your system at any time, which is a decisive factor for process reliability. The recorded measurement data can be used both to document compressed air quality and to identify sources of contamination.
Flow rate, pressure dew point, pressure, active electrical power, temperature and residual oil vapour content
The METPOINT MCA mobile measuring unit has a modular design and is available in various equipment variants (MCA O, MCA OP, MCA OS, MCA OPS). Each variant allows precise measurement of the residual oil content in the compressed air, and the data can be evaluated and documented via an integrated data logger.
Option P extends the METPOINT MCA with a high-precision particle counter capable of detecting even the smallest solid particles down to a size of 0.1 μm. This monitors the functionality of the filter elements installed in the compressed air system, and any filter breakthroughs can be detected immediately.
With option S, the system is extended with additional sensors in a practical case. These sensors record the humidity, flow rate, pressure and temperature of the compressed air. This comprehensive data acquisition helps you identify savings potential, optimise energy efficiency and improve compressed air quality. It also makes it possible to identify weak points in the compressed air network.

Frequently asked questions
What do I need the METPOINT MCA for?
For measurements at points where no stationary measuring equipment is installed. The mobile measuring unit analyses the compressed air quality directly on site.
What does the METPOINT MCA measure?
Every variant measures the residual oil content (oil vapour) in the compressed air. Depending on the option, particle concentration, pressure dew point, temperature, humidity, flow rate, pressure and flow velocity are added.
Which equipment variants are available?
MCA O, MCA OP, MCA OS and MCA OPS. Option P adds a particle counter, option S a sensor case with dew point, flow, pressure and temperature sensors.
How is the oil vapour measured?
With PID sensor technology. An internal reference gas based on the catalyst principle ensures reproducible readings.
What range does the METPOINT MCA measure?
Oil vapour from ≤ 0.01 to 2.5 mg/m³ at a pressure of 3 to 16 bar. The particle counter detects solid particles down to a size of 0.1 μm.
How is the measurement data stored?
All data is recorded in the integrated METPOINT BDL data logger. This allows you to evaluate and document the compressed air quality.
How much effort is commissioning?
Very little. The MCA is delivered fully assembled, stands on an aluminium frame with lockable wheels and is operated via a 7-inch touch display.
What is included in the sensor case?
Dew point, flow, pressure and temperature sensors, connecting cables 5 m long each and a 5 m compressed air hose for connecting to the line.
