Coating Thickness Measurement via Mobile and Bluetooth

  • Easy Operation via App
  • Two Measuring Modes are available
  • Control / Data Transfer via Bluetooth

A new mobile concept for professional coating thickness measurement: The German company ElektroPhysik now offers an intelligent wireless sensor for non-destructive coating thickness measurement and relays sensor data via Bluetooth to a tablet or smart phone. The radio sensor SmarTest is 16 mm [0.63 in] in diameter and 125 mm [4.92 in] in length, and weighs just 48 g [1.7 oz.]. The standard scope of supply comes with a sensor, which has been specially optimized for measuring on thin auto body sheets and can be used for a sheet thickness downwards of 0.3 mm [12 mils].

Easy operation via SmarTest app

It is very simple to operate the SmarTest: Just start the SmarTest app on the mobile device, then switch on the wireless sensor and the Bluetooth connection is established automatically. Now measurements can be taken.

Two Measuring Modes are available

There are two measuring modes available:

  • Single value mode
    The measurement values are taken individually and displayed. This allows 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.

Control / Data Transfer visa Bluetooth

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.
