SIDSP® sensors: now also in a wireless version. Easy-to-use apps turn smartphones and tablets into powerful evaluation and communication devices. The new SmarTest strategy features an app and wireless sensor to provide you with the perfect solution for measuring coating thickness using a smartphone or tablet. The SmarTest version of the SIDSP® sensors for coating thickness measurements combines outstanding measurement accuracy and interference immunity with the advantages of modern wireless technology. Digitally generated measurement data from the sensor are transmitted via Bluetooth to your smartphone or tablet. The SmarTest app acts as an evaluation device and thus replaces the conventional coating thickness gauge.
