What makes the Dansensor CheckMate 4 different from other benchtop gas analyzers?

Dansensor Checkmate 4

The Dansensor® CheckMate 4 is a high-precision benchtop gas analyzer designed for modified atmosphere packaging (MAP) applications. Engineered for accuracy, repeatability, and ease of use, it is widely used in food production facilities, pharmaceutical packaging lines, and quality assurance labs.

Dansensor Checkmate 4 Sensor

Whether you need high-speed sampling or traceable quality documentation, the Dansensor CheckMate 4 provides a scalable solution — and thanks to its user-changeable sensor, you gain flexibility without sacrificing uptime.

✅ 1. Optical Sensor with User-Replaceable Design

 

The CheckMate 4 utilizes non-destructive optical sensors to measure oxygen (O₂) and optional carbon dioxide (CO₂) levels within a sealed package. Unlike electrochemical sensors that wear out quickly, optical sensors offer:

  • Long-lasting accuracy
  • Fast and stable readings
  • Low maintenance

What truly sets the CheckMate 4 apart is that the sensor module is user-replaceable.

Operators can manually swap out the sensor on-site without the need to send the unit back to the manufacturer. This feature:

  • Minimizes equipment downtime
  • Reduces operational disruption
  • Supports continuous production and QA workflows

✅ 2. High-Throughput Performance

The CheckMate 4 is ideal for facilities performing frequent gas content testing. Its fast sampling cycle and integrated needle system allow for:

  • Quick analysis of O₂ and/or CO₂ headspace
  • Efficient handling of multiple batches
  • Reliable testing for flexible and rigid packaging formats

✅ 3. Intelligent User Interface & Data Management

 

Featuring a user-friendly interface and 5” color display, the CheckMate 4 simplifies operation with:

  • Batch tracking & barcode scanning
  • USB and Ethernet connectivity
  • Internal memory for storing up to 10,000 results
  • Password-protected access and audit trails (21 CFR Part 11 compliant, if required)

✅ 4. Trusted Accuracy and Compliance

The system is suitable for:

  • Routine quality checks in food production lines
  • Critical applications in pharma and medical packaging
  • Audit-ready data handling to support HACCP, ISO 22000, GMP, and other quality systems
