Feature: 1. HIGH RESOLUTION: Thickness measuring instrument adopts professional timing chip design, resolution up to 0.01mm, with good stability and measurement accuracy 2. AUTOMATIC SWITCHING: Pipe thickness gauge has the function of automatic gain switching. The instrument automatically chooses the right gain according to the material type and thickness to achieve the best measuring effect 3. MEASURING RANGE: Industrial thickness gauge has a large measuring range of 1-320mm, suitable for standard probes, has the function of measuring the thickness of the substrate through the coating 4. AUTOMATIC DETERMINATION: Pipe thickness gauge meter has the function of QC determination to determine whether incoming materials are qualified according to the set upper and lower limits, so as to realize rapid detection of incoming materials 5. STATISTICAL FUNCTION: Digital pipe thickness gauge can calculate the maximum, minimum and average value of effective measurements automatically, and the statistics can be restarted before measuring data 6. 3 KINDS OF SOUND SPEED ADJUSTABLE: Thickness measuring instrument can adjust the sound speed in 3 ways, known material to select the sound speed, known thickness to set the sound speed, manually set the sound speed 7. LARGE STORAGE CAPACITY: The thickness measuring instrument intelligently identifies the model of the probe, and adapts the display interface according to the probe type. Support large capacity storage, can record 999 data Specification: Item Type: Pipe Thickness Gauge Meter Resolution: 1-100mm: 0.01mm, 100-320mm: 0.1mm Sound Speed Range: 1000~9999m/s Display: 240x160 dot LCD Unit: Mm/inch Battery: 2 x AA dry batteries(not include) Host Size: Approx. 142 x 72 x 28mm / 5.59 x 2.83 x 1.1in Weight: 230 g / 8.1 oz(approx.)
