Key parameters
Pulse-echo corrosion thickness gauge built for rough plant duty — 0.025…36.00 in (0.63…914.4 mm) measuring range, 0.001 in (0.01 mm) resolution, high-speed scan at 100 Hz, extruded aluminum IP65 body, and a 5-year limited warranty.
Key advantages
- Wide PE range — 0.025…36.00 in (0.63…914.4 mm); material/transducer dependent.
- 0.001 in resolution — English & metric; velocity 0.0120…0.7300 in/µs (305…18,542 m/s).
- High-speed scan — Captures lowest reading during scan at 100 Hz PRF display rate 10 Hz / PRF 200 Hz.
- Plant-tough package — Extruded aluminum, nickel-plated end caps, sealed keypad, IP65, −30…+75 °C.
- 5-year limited warranty — Dual-element 1–10 MHz transducers with locking LEMO connectors.
Typical applications
- Corrosion and pitting surveys on tanks, boilers, tube, and pipe.
- Glass and general material thickness checks.
- Plant walk-downs needing a durable handheld UTG without on-gauge datalogging.
Selection guide
- ZX-3 vs ZX-5 / ZX-5 DL — ZX-3 is the performance/simplicity gauge; choose ZX-5 series when you need differential/alarm modes, USB-C download, or 10,000-reading datalogging (ZX-5 DL).
- Transducer — Dual-element 1–10 MHz; confirm diameter/temperature rating for the material.
- Units / velocity — Set material velocity; probe-diameter selection improves linearity.
- Power — Two AA (alkaline / NiCad / lithium); ~45 h alkaline typical.
Common mistakes
- Expecting onboard datalogging or USB download on ZX-3 — those are ZX-5 DL features per OEM family datasheet.
- Wrong material velocity → large thickness error.
- Using a worn or wrong-temperature dual-element probe on hot surfaces.
- Skipping zero (manual/auto) after probe change.
When to RFQ / what to tell us
- Confirm ZX-3 (not ZX-5 / ZX-5 DL); transducer frequency/diameter.
- Material / thickness band; English or metric preference.
- Quantity and ship-to country.

FAQ
Q: Does ZX-3 store readings? A: No — sequential datalogging (40×250 = 10,000 readings) and USB download are ZX-5 DL features per the ZX Series datasheet. ZX-3 is the non-logging gauge.
Q: What transducer? A: Dual-element transmit/receive, 1–10 MHz, locking LEMO; custom transducers available for special applications.
Q: What should I send for a quote? A: Confirm ZX-3, transducer needs, material/thickness band, quantity, ship-to.
