Ultrasonic Wall Thickness Gauge for PET Preforms

Handheld ultrasonic thickness gauge with a high-frequency probe for measuring preform sidewall and base thickness without cutting. Used by preform and bottle makers to verify uniform wall distribution and to set injection parameters.

Specification

A 10 MHz probe sends a pulse through the plastic wall and the gauge computes thickness from the echo time using a PET sound velocity setting. The tool shows readings to 0.01 mm on a backlit screen. It replaces cutting and micrometer measurement of sample preforms.

Features

• 10 MHz probe for thin plastic walls
• Sound velocity presets for PET, PP and HDPE
• Large backlit display with min/max hold
• Couplant gel based measurement for curved surfaces
• Data memory with USB transfer
