SmarTest Wireless Coating Thickness Sensor
Handheld wireless coating thickness measurement instrument with Bluetooth that turns your smartphone or tablet into a coating thickness measurement tool.
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, 125 mm in length and weighs just 48g. The sensor is similar in size to a ballpoint pen so you can carry it in your top pocket along with your smartphone.
The standard scope of supply comes with the F 2.6 (Ferrous) or FN 2.6 (Non-Ferrous) 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 / 12 mils.
You can connect any SIDSP sensor to SmarTest and cover a wide range of coating thickness measurement tasks.
The easy to use SmarTest App has a step by step guide to operate the instrument:
- Start the SmarTest app on the mobile device
- Switch on the wireless sensor and the Bluetooth connection is established automatically
- Take measurements
Applications:
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)
Features:
- 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 (English, German, French and Chinese)
- Wear resistant probes (sensors) 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
