SmarTest: Intelligent Bluetooth sensor for coating thickness measurement
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 is 16 mm in diameter and 125 mm in length somewhat like a thick ballpoint pen and weighs just 48 g.
This means that you can carry the SmarTest with you anywhere.
The standard scope of supply comes with the F 2.6 or FN 2.6 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.
Operation
It is very simple to operate the SmarTest:
•Start the SmarTest app on the mobile device
•Switch on the wireless sensor and the Bluetooth connection is established automatically
•Take measurements
The SmarTest app helps you through all steps with context-sensitive help texts in 4 languages currently.
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.
