The ZX gauges use the 0 – 1st Echo technique to measure remaining wall thickness on uncoated material. It can be used to measure thickness, detect internal pitting and measure when the opposite surface is highly corroded.
The ZX-1, like the MX-1, is designed for simplicity. The gauge is pre-calibrated for steel* which eliminates the need for a calibration block and careful calibration by a trained inspector. It is always calibrated and ready to use - just Probe Zero and measure.
*The ZX-1 can be unlocked and reset to other material sound velocities if needed.
The ZX-3 replaces the MX-3 with fully adjustable sound velocity + 8 presets. Standard Probe Zero or Automatic (No Zero Block) Probe Zero. The most important feature is the High Speed Scan mode which provides for better detection of small pitting.
The ZX6/ZX-6DL replaces the MMX-6/MMX-6DL and ER versions. The ZX-6 has all the ZX-5 features plus Echo-Echo Through-Coating capability with Time Dependent Gain (TDG). TDG is used in both Pulse-Echo (P-E) and Echo-Echo (E-E) modes depending on transducer and frequency selected. TDG electronically compensates for signal loss due to increased distance and the loss of signal strength due to attenuation.
