Model Introduction
PM9 Standard Ultrasonic Thickness Gauge
Versatile and powerful for general industrial thickness measurement. Supports thickness, sound velocity and transit time testing. Equipped with temperature compensation, automatic gain control (AGC/TDG) and pause function for frozen waveform adjustment. Compatible with all ultrasonic probes for thin-walled materials, thick materials, corroded pipes and coated metal measurement.
PM9HF High-Frequency Ultrasonic Multi-Layer Coating Thickness Gauge
Works as an acoustic microscope with 75MHz high-frequency ultrasound. Patented MULTI-MEAST™ technology measures up to 5 independent coating layers simultaneously. Minimum measurement down to 0.05mm (steel) and 12μm for coatings. Suitable for automotive, machinery, ship, wind turbine and wood coatings on steel, aluminum, plastic, carbon fiber, glass and wood substrates.
PM9SI Corrosion Scanning Imaging Thickness Gauge
Professional for corrosion detection of pipelines, pressure vessels and metal structures. Includes encoded B-scan and three types of scanners (car-type, cable pull encode, wheel-type). Adaptive probe holder fits various pipe diameters. Intuitive B-scan imaging quickly identifies wall-thickness reduction and defects, retaining all standard PM9 functions.
PM9MX Multi-Channel Ultrasonic Thickness Gauge
Works with MX-4 multi-channel converter to support up to 4 probes for simultaneous multi-point measurement. Each channel has 20+ independent adjustable parameters. Large screen displays multi-channel waveforms and thickness data synchronously. Detachable converter design for flexible use, same as standard PM9 when not connected to MX-4.
PM9 PRO Professional Ultrasonic Thickness Gauge
For standardized and traceable inspection. Supports workpiece image import and up to 999 inspection points marking with independent alarm limits. Provides data trend analysis (line charts & bar charts) and PDF/Excel report generation. One template can measure up to 1,000 workpieces, realizing full-process traceable inspection.
