Precision Thickness Gauge - PZX-7/PZX-7 DL

The PZX-7 series gauges are our basic single element precision gauges, and equipped with a variety of measurement modes to address a number of potential applications. They can use both high and low frequency transducers with a variety of diameter options. Both models have USB-C connectivity, with and without data storage, and serial over USB-C using a CDC class. Optional RS232 and bluetooth modules available for connection with data collectors and custom apps.
