MiniTest 745 Coating Thickness Gauge

Made in GermanyDesigned for utmost flexibility for quality control and inspections, the sensor of the MiniTest 745 model can be easily converted from a built-in sensor into an external one. So even difficult to access areas can be reached without problems.

The new MiniTest 745 coating thickness gauges are the solution to all your coating thickness problems where a reliable finish and perfect product appearance play a major role for long-term value and success, e.g. in the automotive and shipbuilding industry, steel- and bridge construction or in the electroplating industry, to name but a few industries.

The MiniTest 745 is ergonomically designed and its rounded shape allows the MiniTest gauge to fit perfectly into the palm of your hand. Also, the MiniTest 745 gauges feature a measuring speed setting option that allows adjustment to changing requirements for utmost efficiency and optimum productivity: taking many readings in a short time with medium precision or taking only a few readings with increased accuracy.

All MiniTest 745 sensors perfectly compensate for irregular shaped surfaces thanks to the predefined calibration methods that are available to adapt to a wide range of different surface conditions and accuracy requirements.

The MiniTest 745 gauges are equipped with the new SIDSP® sensors.
SIDSP® is a world wide leading technology for coating thickness sensors. With this new technology, another new benchmark for innovative coating thickness measurement has been set. SIDSP® stands for Sensor-Integrated Digital Signal Processing – a technology where the signals are completely processed into digital form inside the sensor at the time and point of measurement. SIDSP® sensors are manufactured according to completely new state-of-the-art production techniques.

Unlike conventional techniques, the SIDSP® sensors create and control the excitation signals for the sensor head inside the sensor. The return signals are directly digitally converted and processed at a 32 bits accuracy to give you the complete coating thickness value. For this technique, highly sophisticated methods of digital signal processing are used as known from modern telecommunication technologies (mobile phone networks) such as digital filters, base band converting, averaging, stochastic analysis, etc. This enables the user to achieve a signal quality and precision unmatched so far with analogue signal processing. The thickness value is digitally transmitted via the sensor cable to the display unit. Setting a new standard in coating thickness measurement, this technology offers decisive advantages and improvements compared to the commonly used analogue sensors.

The new SIDSP® sensors guarantee the following:
- High stability of measuring signals
- SIDSP® sensors are wear-resistant
- SIDSP® sensors’ characteristic curves feature high accuracy
- SIDSP® sensors are highly insensitive to changes in temperature
- SIDSP® sensors provide excellent adaptability
- SIDSP® sensors are highly insensitive to changes in temperature
- SIDSP® N and FN sensors compensate for substrate conductivity
- Future-oriented solutions
