德國MiniTest 740塗層測厚儀

Application: 

Designed for utmost flexibility for quality control and inspections, All 740 probes can be connected using supplied extension cable or inserted directly into the gauge housing for easy 1-Hand operation.

The new MiniTest 700 Series Coating Thickness Gauges offer a reliable and accurate solution to all your coating thickness measurement tasks, especially when a reliable finish and perfect product appearance play are of major importance and add value to your product such as in the automotive and shipbuilding industry, steel and bridge construction, appliance manufacture and more.

The MiniTest 700 is ergonomically designed and its rounded shape allows the MiniTest gauge to fit perfectly into the palm of your hand. Also, the MiniTest 700 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 720 probes 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.

All MiniTest 700 Series gauges are equipped with the new SIDSP® technology. SIDSP® is a brand-new technology being applied to coating thickness gauges for the first time. This new technology sets a new benchmark for innovative coating thickness measurement worldwide.

SIDSP® stands for Sensor-Integrated Digital Signal Processing – a technology where the signals are completely processed into digital form inside the probe at the time and point of measurement and are manufactured according to new state-of-the-art production techniques.

Unlike conventional techniques, the SIDSP® probes create and control the excitation signal for the probe. 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 with traditional analogue signal processing found in most other coating thickness gauges. The thickness value is digitally transmitted via the probe cable to the display unit setting a new standard in coating thickness measurement, offering significant advantages compared to the commonly used analogue probes.

The new SIDSP® sensors guarantee:

  • Highest accuracy and repeatability
  • Wide range of probes for a wide variety of applications
