Overview
Enviro Test Consrtuct Mini Digital Ultrasonic Thickness Gauge for testing the thickness of metal objects has the function of penetrating the coating and can directly measure the thickness of the substrate without removing the coating on the surface of the object to be measured. Coatings applicable to this function include paint layer, plastic coating, etc. This function is realized by measuring two continuous bottom echoes of the substrate. This mode also has more advantages: zero-free calibration, high stability of indication value, and zero drift.
Features
- Two modes: Pulse-echo for standard thickness measurement, and Echo-echo for measuring substrate thickness without removing the paint layer.
- One-point calibration is for routine measurements, while two-point calibration improves accuracy for curved surfaces or special applications.
- Measurement error: ±0.05 mm (less than 10 mm), ±5% H+0.01 (more than 10 mm) Note: H is the thickness of the object to be measured.
- V path correction: v sound path correction to compensate nonlinearity of the bimorph probe
- For minimum scanning, drag the probe along the object’s surface, and the instrument automatically locates and measures the thinnest thickness.
- Application software: UmView software is used to transmit, store, analyze, and edit documents of measurement data (optional)
- Has the function of penetrating the coating, the measuring range is 0.12in to 0.79in (3 to 20mm). (Use standard probe LM-2D Only)
