Ergonomics

When developing the ACS Plus model range, great importance was attached to functionality, flexibility and reliability. Ergonomics in use and handling are at the forefront. The compact and robust design makes the ACS Plus particle counter particularly easy to transport and safe to set up.

User-friendliness

The large-format display with touchscreen function and clear menu navigation means that even extensive settings can be made simply and easily. In addition, an integrated access authorization concept makes it easy to assign specific access rights to functions for individual operators. The anti-reflective surface of the display makes it possible to read data even from greater distances.

GMP-compliant design

Clear surface design is one of the prerequisites for using a device in GMP-controlled areas. This naturally also applies to particle counters. In this context, cleanroom suitability and resistance to cleaning agents and disinfectants are the most important technical features that have been implemented in the design of the surface properties.

Flexible monitoring

Depending on the operating conditions, the ACS Plus particle counter can be used flexibly as a stand-alone unit or as a networked monitoring system. If required, it is possible to monitor and record temperature curves, relative humidity, differential pressure and flow velocities at any time via a device interface with corresponding sensors. The possibility of integrating an alarm console has also been taken into account.

Always the right configuration

Cumbersome reconfiguration of the device for standardized measuring tasks is a thing of the past. With the ACS Plus particle counter, it is possible to store a variety of measuring point-related master data, such as measuring point designation or alarm and limit values, in the device. Particularly when carrying out routine measurements, this allows you to achieve considerable savings in set-up times and minimize the risk of errors due to incorrect entries.

Flexible in terms of functionality

Yesterday: US Federal Standard 209 E. Today: ISO 14644-1 and Annex 1 to the EU GMP guidelines. And tomorrow? Whatever happens, you are always up to date, because the ACS Plus particle counter learns. The internal device firmware is updated via an integrated CAN interface so that you can also fully meet future requirements.

Everything at a glance

The ACS Plus also stands out from the crowd when it comes to evaluating measured values. A wide range of functions are available to make it easier for you to process and evaluate measured values. Thanks to the generous display format, it is possible to display raw data not only in tabular form, but also graphically.

Evaluation and processing

You can also choose between distributive and cumulative measured value output. For further computer-aided evaluation and archiving of the recorded measured values, the option of data export has been created. The selected data format is compatible with many common spreadsheet programs.
