The Dakota Ultrasonics ZX-3 Corrosion Thickness Gauge is a durable dual element gauge designed for rough conditions. This IP65 rated unit is ideal for detecting corrosion and pitting in applications on glass, tanks, tubes and pipe, and boilers. The ZX-3 is protected by an extruded aluminum body and nickel-plated aluminum end caps (gasket sealed). The key pad is made with a sealed membrane to make it resistant to water and petroleum products. A backlit display allows the operator to view readings even in dim settings.
Depending on the material and transducer type, the ZX-3 has a range of 0.025" to 36". This gauge features a high speed scan (speed at 100Hz), which displays the lowest reading found during a scan. A bar graph shows the stability of readings during inspection. Velocities can be set manually using the CAL key or selected from a list of 8 common material velocities.
