The model MiniTest 735 comes with an external sensor.

The MiniTest 735 coating thickness gauge is 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 a few industries.

The MiniTest 735 is ergonomically designed and its rounded shape allows the MiniTest gauge to fit perfectly into the palm of your hand. It also features 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.

The MiniTest 735 facilitates non-destructive coating measurement of non-magnetic coatings (paint, synthetic material, chromium etc.) on ferromagnetic substrates (steel) and of insulating coatings (varnish, enamel, synthetic material, anodising aluminium etc.) on conductive substrates (aluminium, copper, austenitic stainless steel).

Its 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 735 gauge is 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 sensorhead 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’ characteristic curves feature high accuracy
- SIDSP® sensors provide excellent adaptability
- SIDSP® N and FN sensors compensate for substrate conductivity
- SIDSP® sensors are highly insensitive to changes in temperature
- SIDSP® sensors are wear-resistant
- Future-oriented solutions

The delivery of the device includes the data transfer software MSoft 7 basic.
