Test strips are everywhere—water testing, food safety, industrial processes, and environmental monitoring. They’re fast, portable, and cost-effective. But they come with a persistent limitation: human interpretation.
Two technicians can read the same strip and report slightly different results. Under varying lighting conditions or time delays, accuracy drifts further. In industries where compliance and consistency matter, this subjectivity becomes a measurable risk.
The solution isn’t to replace test strips—it’s to upgrade how they’re read. That’s exactly where QUANTOFIX Relax from Vendart fits in: a reflectometer that transforms simple strip testing into objective, data-driven analysis.
The Problem with Manual Test Strip Reading
Despite their convenience, traditional strip-based testing has inherent variability:
- Colour interpretation bias across operators
- Lighting inconsistencies affecting visual comparison
- Timing sensitivity—results must be read within precise windows
- Lack of digital records for audits and traceability
In regulated sectors, even small deviations can lead to:
- Compliance issues
- Product quality inconsistencies
- Re-testing costs
- Operational inefficiencies
As testing volumes grow, so does the need for standardisation.
QUANTOFIX Relax: Bridging Simplicity and Precision
QUANTOFIX Relax from Vendart is designed to combine the ease of test strips with the accuracy of instrumental analysis.
Instead of relying on visual matching, it uses reflectometric measurement—a method that quantifies colour intensity and converts it into precise, repeatable values.
What makes it stand out?
- Works with standard QUANTOFIX and pH-Fix strips (no proprietary consumables required)
- Delivers objective, digital results
- Eliminates operator-dependent variability
- Integrates seamlessly into existing workflows
In short, it upgrades your current testing process without forcing a change in consumables or methodology.
How Reflectometry Improves Accuracy
Reflectometry measures how much light is reflected from the test strip surface. Each colour intensity corresponds to a concentration level of the target analyte.
Compared to visual interpretation, this approach offers:
- Higher reproducibility across users and locations
- Reduced error margins in borderline readings
- Consistent timing control during measurement
- Quantifiable outputs instead of subjective estimates
For businesses, this translates into better decision-making backed by reliable data.
Built for Throughput and Operational Efficiency
QUANTOFIX Relax isn’t just about accuracy—it’s engineered for real-world workloads.
Performance highlights:
- Up to 50 test strips per hour
- Data storage for 200 measurements
- Automatic calibration and self-testing
- Microprocessor-controlled system
This makes it ideal for environments where testing is frequent and time-sensitive—such as manufacturing lines, water treatment facilities, and quality control labs.
Designed for Practical Use
The device balances technical capability with user-friendly operation:
- Touchscreen interface with alphanumeric input
- Backlit LCD for clear visibility
- Multi-language support (including English, French, Spanish, and more)
- Compact form factor (200 × 160 × 75 mm, 0.71 kg)
It’s equally suited for bench-top use or mobile testing setups.
Connectivity and Data Integration
Modern testing isn’t just about results—it’s about what you do with them.
QUANTOFIX Relax supports:
- USB and RS232 interfaces for data transfer
- Keyboard and barcode scanner integration
- Free software updates via PC/internet
- Integrated thermal printer for instant documentation
These features enable:
- Digital record-keeping
- Faster audit preparation
- Seamless integration into LIMS or reporting systems
- Improved traceability across batches
Reliability in Diverse Environments
The device is built to perform consistently under typical industrial conditions:
- Operating temperature: 10–40°C
- Humidity tolerance: up to 80% (non-condensing)
- Power options: AC supply or battery operation (6 AA batteries)
This flexibility allows it to function across labs, production floors, and field environments.

The Business Case: Why It Matters
Switching to an instrument-assisted strip reader isn’t just a technical upgrade—it’s a strategic move.
Key benefits:
- Reduced variability = fewer errors
- Faster throughput = higher productivity
- Digital records = easier compliance
- No special consumables = controlled costs
In industries where margins depend on precision and repeatability, these gains compound quickly.
Final Thoughts
Test strips have always been valued for their simplicity. But as industries demand more accountability, that simplicity needs reinforcement.
QUANTOFIX Relax from Vendart delivers that balance—retaining the speed and convenience of strip testing while introducing the consistency, traceability, and confidence of digital analysis.
For organisations looking to standardise testing without overhauling their processes, it offers a practical, scalable solution—one that turns everyday measurements into reliable, decision-ready data.
