SmarTest 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.
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
- 1-point calibration on the uncoated object to be measured (zero point calibration)
- 2-point calibration (zero point calibration + 1 layer/sheet)
- Precision coating thickness gauge with digital sensor
- Can be connected to any SIDSP sensor
- Transfer of measuring data via Bluetooth, range of approx. 10 m
- Display and operation by app in 4 languages currently (German, English, French and Chinese)
- 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
SmarTest is delivered as a kit including:
- SmarTest
- Calibration set with calibration foils and reference zero test plate(s)
- USB charger with micro-USB cable
- Operating manual
- Manufacturer‘s certificate
- Storage case
