ElektroPhysik SmarTest Bluetooth Coating Thickness Sensor is an 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 SmarTest has a diameter of 16 mm and a length of 125 mm and weights just 48 g. This means that you can carry the SmarTest with you anywhere.

The standard scope of supply comes with the F 1.5 or FN 1.5 sensor, which has been specially optimised for measuring on thin auto body sheets and can be used for a sheet thickness downwards of 0.3 mm.

You can connect any SIDSP sensor to SmarTest and cover a wide range of coating thickness measurement tasks.

Comfortable Apps can now turn smart phones and tablets into effective evaluation and measuring devices. The new SmarTest concept consisting of an app and a wireless sensor offers the perfect solution for measuring coating thickness with the help of smart phones and tablets.

The SmarTest version of SIDSP®-sensors to measure coating thickness combines exceptional precision in measuring and resistance to interference with the advantages of the modern wireless technology. The digitally generated readings on the sensor are relayed by Bluetooth to your smart phone or tablet.

The SmarTest App functions as a device for evaluating and thus replaces a conventional coating thickness gauge.

Features

• Powerful and versatile gauge with new ergonomic design making it ideal for on-site testing
• User-friendly key-pad layout with menu driven operation
• Variable pre-set test voltages specific to material thickness
• High voltage probe with equipment-on and pore indicator (red LED)
• Light-weight and hand-held test electrodes provide convenient operation
• Test method conforms to DIN 55 670
• Backlit display to indicate current test voltage, number of pores and material thickness
• Residual voltage indicator
• Alarm signal when exceeding pore limit setting (Limit)
• Power supply: AC operated or battery operated via integrated storage battery (C-cells)
• Electrical safety provisions according to VDE 0411, part 1: probe voltage and maximum discharge rate stay below the limit values as specified by the safety standard.
• Low-battery indicator

More

• The App functions include a clear display of current measuring value, statistical evaluation, storage of measuring values in files, 2-point calibration, measuring unit metric/imperial switchover and export of the series of measurement in the CSV format. All the functionalities of a smart phone are available for data transfer.
• For instance, you have the ease of sending your measuring data to any receiver by email. The intelligent SmarTest sensor is made to fit any jacket pocket. In combination with smart phones or tablets this forms an ultra modern full-set for experts on site to measure coating thickness.
• Long battery life: the sensor equipped with the LiFePo battery can function for up to 8 hours in continuous operation. Readings exceeding the set limits are indicated on the sensors‘s green/red LED. SmarTest functions on old smart phone models as well as on the latest ones. The dual Bluetooth module ensures a long operating time in modern devices thanks to the Bluetooth low energy mode.
• SmarTest is a most flexible solution: It can also be supplied in other combinations with any of the SIDSP®-sensors of the MiniTest 700 series to cover a wide field of different applications.

Operation: 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.

Application

Non-destructive coating thickness measurement of:

• Non-magnetic coatings like varnishes, enamels, chromium and zinc on ferromagnetic base materials (e.g. steel)
• Insulating coatings like varnishes and anodising aluminium on nonferrous metals (e.g. aluminium, austenitic stainless steel, brass)

Measuring Modes: 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.

Control / Data Transfer

• 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 Functions

• The SmarTest 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.

Calibration: Three calibration modes are available:

• Manufacturers calibration
• point calibration on the uncoated object to be measured (zero point calibration)
• point calibration (zero point calibration + 1 layer/sheet)
