QUANTOFIX Relax Test strip reader

Reflectometer for evaluation of test strips. The QUANTOFIX Relax is the ideal device for the objective evaluation of our QUANTOFIX test strips. It combines the simplicity of test strips with the safety of instrumental analysis and thus the best out of these two worlds. The QUANTOFIX Relax does not require any special strips, but evaluates the normal pH‑Fix and QUANTOFIX test strips.
Excellent usability
All functions of the device can be selected with the touch screen display. Therefore, the operation is simple and intuitive, without the need for extensive training. The auto-start function initiates the measurement as soon as the test strip is placed on the strip holder. Therefore, it is not necessary to touch the device for performing a measurement. Contaminations are reliably avoided. Frequently used parameters can be stored as favourites. Simple tapping can quickly access these favourites during operation.

Quantitative results
The optics of the QUANTOFIX Relax has been proven for years in medical technology and supplies secure and standardized values. Thereby an accuracy of ≤ 10 % is achieved for many parameters; a hardly achieved level in the visual analysis of test strips, yet. The evaluation with the QUANTOFIX Relax is not interfered by external factors and is therefore absolutely objective and precise. The estimation of measured values between the gradations of the scale is omitted.

Documentation and data transfer
The QUANTOFIX Relax allows the assured documentation of analytics with test strips. Results are printed immediately after the measurement. The printout can be e.g. appended to a production protocol or kept for later quality controls. The transmission to an information system can be realized easily. In addition, the data are stored in the device and can be simply read out or printed again later on.
