SmarTest Coating Thickness Sensor

The SmarTest is an intelligent bluetooth wireless sensor for non-destructive coating thickness measurement and relays sensor data via Bluetooth to your tablet, smart phone or to the coating thickness gauge MiniTest 745.

SmarTest Coating Thickness Sensor


  • Intelligent wireless sensor for non-destructive coating thickness measurement and relays sensor data via Bluetooth to your tablet, smart phone or to the coating thickness gauge MiniTest 745
  • The radio sensor is somewhat like a thick ballpoint pen
  • Can connect any SIDSP sensor to SmarTest and cover a wide range of coating thickness measurement tasks.
  • Simple to operate
  • Texts in 4 languages (German, English, French and Chinese)
  • There are two measuring modes available:
    • Single value mode - The measurement values are taken individually and displayed. This enables you to take coating thickness values of the object to be measured at multiple points and then to evaluate them statistically.
    • Continuous mode - After placing the sensor the measuring values are taken continuously and displayed. This mode is suited for calculation of layer thickness distribution on a restricted surface and to locate the thin and thick sections. The measuring values calculated on continuous mode can be saved in the statistics by briefly pressing the power button.
  • Sensor control and data transfer of the measuring values is done via Bluetooth 4.0 / Bluetooth Smart (low energy). The sensor and mobile device can be placed about 10 m away from each other, even farther under good transmission conditions.
  • App shows the current measuring values, the statistical evaluation and helps store control and calibration of the sensor. There is an option of the metric (µm, mm) and imperial (mils) formats for display and processing of measuring values. Storage and transfer / download of measuring values is done in the CSV format.
  • Three calibration modes are available: Manufacturers calibration, 1-point calibration on the uncoated object to be measured (zero point calibration) and 2-point calibration (zero point calibration + 1 layer/sheet)
  • Non-destructive coating thickness measurement: Non-magnetic coatings like varnishes, enamels, chrome and zinc on ferromagnetic base materials (e.g. steel). Insulating coatings like varnishes and anodising aluminium on non-ferrous metals (e.g. aluminium, copper, die-cast zinc)
  • Wear resistant probes with a virtually unlimited life
  • Optimal temperature compensation by individual compensation characteristic curves
  • High precision characteristic curves with up to 50 support points in the manufacturer’s calibration
  • Battery charge lasts for more than 8 hours of operation
  • Batteries are charged using a mini USB socket
  • Internal battery control prevents incorrect measurements caused by low battery charge
  • Storage and transmission of measuring data in the CSV format

Instructions for Use

It is very simple to operate the SmarTest:

  1. Start the SmarTest app on the mobile device.
  2. Switch on the wireless sensor and the Bluetooth connection is established automatically.
  3. Take measurements.

The SmarTest app helps you through all steps with context-sensitive help texts in 4 languages currently.
