Article code: TM290

TM290 is a new type of handheld high-precision digital ultrasonic thickness gauge with A/B scanning.

It adopts the principle of ultrasonic thickness measurement based on pulse reflection. It is suitable for the measurement of material thickness that can make ultrasonic wave propagate in it at a constant speed and get the reflection from its back. The measurement resolution is 0.001mm and the measurement range is as thin as 0.15mm (steel).

This product can accurately measure plates and processed parts. On the other hand, it can monitor the thinning degree of pipes and pressure vessels in production equipment after corrosion during use.

It can be used in petroleum, chemical industry, metallurgy, shipbuilding, aerospace, energy and other fields.

this product has A-scan mode, B-scan mode and numerical display mode;
the measurement range is wide, and the unique "multiple echo" technology is adopted to realize the measurement of ultra-thin parts, with a minimum measurement thickness of 0.15mm (steel)
this product can measure the thickness with high precision, and the maximum measurement resolution can reach 0.001mm; The repetition resolution can reach ± 0.002mm
it has the functions of penetrating coating and echo to echo measurement, which is used to measure materials with paint layer and coating on the surface
multiple measurement modes: mb-e, E-E and me-e modes meet the measurement of conventional thick workpieces; Thin mode realizes the measurement of thin parts
numerical modes include: conventional thickness value mode, difference / reduction rate mode and maximum value mode
two gain modes: automatic gain / manual gain
manual shutdown and automatic shutdown can be set, with energy-saving function
it supports a variety of probes, including double crystal probe and single crystal probe, and supports up to 20MHz high-frequency probe
it supports mass storage and can store 100000 thickness values, 500 groups of A-scan waveforms and 500 groups of B-scan waveforms at the same time
Large 3.5-inch color TFT-LCD display with 320x240 high definition (QVGA) resolution
It has a variety of calibration methods, supports one-point calibration, multi-point calibration and manual calibration modes, and can calibrate sound velocity and probe zero position at the same time
v-path correction of double crystal probe.
conversion of metric and British system; It can switch between millimeter and inch units
Chinese and English display
