UM-1D Thru-Paint or Coating Ultrasonic Thickness Gauge Introduction The UM-1D is a simple to use, high accuracy, hand-held Ultrasonic Thickness Gauge with the ability to measure through paint and coatings and even to eliminate the thickness of the paint or coating. You can now test painted tanks, pipes, etc., without needing to remove the paint or make corrections for the paint thickness. Features and Specifications Operating principle: Standard mode: P-E ( pulse-echo) method with dual-element probes Coating mode: E-E ( echo-echo) method with dual-element probes Probe zero adjustment: Selectable: 1-point calibration: normal measurement 2-point calibration: curve surface measurement or other special application with a high precision V-path correction: Automatic Measuring range: 0.8mm to 300mm; 0.031in to 11.81in in standard mode 3.0mm to 18.0mm; 0.118in to 0.709in in through coating mode Depending on probe, material and surface condition Digital resolution: 0.001in or 0.1mm Units: Selectable: inch or mm Display: 128× 64 dot-matrix LCD screen ( 1.65in× 2.24in; 42mm× 57mm) EL backlight and switchable contract ratio Digit height: 0.54in or 13.75mm Measurement update rate: 4 Hz in standard measurement mode 25 Hz in MIN capture mode Material velocity range: 1000 to 9999 m/ s; 0.039 to 0.394 inch/ µ s Power: Two 1.5V AA alkaline batteries Warning with low battery voltage Operating time: Up to 200 hours ( without backlight) with alkaline batteries, depending on operating mode Auto shut-off: After 5 minutes of non-use Operating temperature: -10 to + 50 ; + 14 to + 122 Specification to -20 / -4 on request Size: 5.86in× 2.87in× 1.25in; 149mm× 73mm× 32mm ( H× W× D) Weight: 200g; 7oz ( including batteries) Data logger capacity: Up to 500 readings can be divided into a maximum of 5 files ( user-selectable) Operating language: English and Chinese Measuring error: Up to 1in: ± 0.002in or ± 0.1mm Above 1in: ± 1% H H is the height of the testing object Repeatability: ± 0.001in or ± 0.1mm Application software: UMVIEW Interfaces: Serial RS 232C port in combination with a communicative cable; Data transfer parameters: 8 bits, 1 stop bit, 9600 baud, no parity.
