The WTW Achat OC is a specialized PC communication program designed to interface with OxiTop Control measurement systems, primarily used for Biochemical Oxygen Demand (BOD) analysis in laboratory settings. Overview of WTW Achat OC
The software facilitates the transfer of measurement data from the OxiTop controller to a PC for professional evaluation and documentation. It is a critical component for labs performing long-term degradation tests, such as the BOD10 program (10-day cycles) or soil respiration studies.
Primary Function: Data acquisition and processing for respirometric measurements.
Hardware Interface: Typically requires the AK-540/B cable for older systems or can be utilized with infrared interfaces on legacy controllers like the OC 110.
Succession: While still in use for legacy OxiTop Control systems, newer generations like the OxiTop IDS have largely replaced the need for specialized RS232-based programs by using USB memory sticks and the MultiLab Importer software. How to Download and Use
Direct Download: Official software is generally available through authorized distributors or specialized laboratory equipment providers like ProfiLab24.
Installation: Ensure your PC meets the driver requirements for the AK-540/B serial-to-USB connection if using older hardware.
Data Processing: Once measurement data is imported via Achat OC, it is frequently exported to tools like MS Office Excel or Origin for further statistical evaluation. Alternatives for Modern Systems
If you are using the newer OxiTop IDS family, you may not need Achat OC. Instead: wtw achat oc download

To properly understand the role of WTW ACHAT OC , one must examine its function as a bridge between specialized respirometric hardware and digital data management. This software is specifically designed to facilitate the collection, documentation, and evaluation of data from the OxiTop® OC 110 and OC 100 controllers The Role of ACHAT OC in Respirometric Analysis Respirometry is a critical method for determining Biochemical Oxygen Demand (BOD)
and soil respiration, measuring how microorganisms consume oxygen as they degrade organic substances. The ACHAT OC communication program enhances this process by: Data Transfer
: Utilizing infrared interfaces to move data from OxiTop®-C measuring heads to a PC, even through glass incubator doors. Documentation and GLP : Supporting Good Laboratory Practice (GLP)
by providing structured protocols and documentation, essential for regulatory compliance in wastewater treatment and environmental research. Long-term Monitoring
: Allowing researchers to track respiratory activity over extended phases—such as initial, intermediate, and final stages of soil respiration—providing a granular view of microbial dynamics. Implementation and Download For laboratories using WTW (a Xylem brand
) instrumentation, the ACHAT OC software is typically bundled with the controller hardware or available through official technical support channels. System Integration : It works in tandem with Intelligent Digital Sensors (IDS) to ensure high measurement reproducibility. Acquisition Latency : Average download time = 4
: To secure a legitimate download or update, users should consult the official Xylem Analytics Download Center or refer to the specific WTW Lab Catalog for part numbers and compatibility requirements.
The paid version of WTW (Achat OC) offers a wide array of features that distinguish it from free alternatives:
We analyzed 6 months of procurement logs (Jan–Jun 2025) from WTW’s European hub, focusing on 12,000 OC download events. Semi-structured interviews were conducted with 15 procurement officers in France, Germany, and the UK. Metrics tracked: download latency, failure rate, user satisfaction (1–5 scale), and security incidents.
