Phynix Surfix® SX / EX

Modern coating thickness measurement: graphic display, PC connection, easy operation, as well as the proven PHYNIX probes

The outstanding feature of this new PHYNIX gauge is the brilliant color graphic display with improved text presentation and allows a variety of different operating languages. The standard now includes English, German, French, Italian, Spanish, Turkish, Czech and Chinese. The internal memory was greatly enlarged compared to the Surfix series and now allows the storage of up to 2,000 measured values. The connection to a computer is simply via USB 2.0. PHYNIX.connect, a data transmission program for all modern Windows systems, facilitates the transfer of measured values into Excel.

Two models are available: the Surfix® SX can be connected to all probes from the PHYNIX probe program. This ensures the highest possible flexibility which enables the device to fulfill many different measurement tasks. The Surfix® EX devices with the fixed standard probe are suitable for applications where the measurement tasks are clearly defined. It is easy to use and also more cost efficient compared to the Surfix® SX with the high-quality plug-in Connection.
