The A1208 ultrasonic thickness gauge is a universal device used to measure the thickness of parts made from various materials. A prerequisite for this is the ability of the material to absorb ultrasound.
A combined sensor is supplied with the ultrasonic thickness gauge, which allows measuring parts from a thickness of 800 microns to 300 mm. The device is made of high quality materials with high resistance. Operation of the equipment in conjunction with a separately-combined sensor allows you to find corrosion foci of the ulcer type. The device can be used in a wide temperature range from -30 to +50 degrees.
The purpose of the A1208 thickness gauge
The device supports operation with combined and separately combined converters. It is intended for measuring the wall thickness of metal, cast iron, steel, plastic and other products with high attenuation of ultrasonic waves. It can be operated in difficult climatic conditions in a wide temperature range.
The use of an A1208 ultrasonic thickness gauge with a combined transducer equipped with a tread resistant to wear makes it possible to:
- Measure the thickness of thick-walled products made of plastic, cast iron, metal and other materials with a high level of ultrasonic attenuation.
- Determine the thickness of metal products coated with paintwork. The device determines the thickness of the object without taking into account the coating layer with an object thickness of up to 15 mm and a coating thickness of 11 mm.
- Scan controlled objects.
The search for corrosion points of thin-walled pipes of small diameter and the measurement of their wall thickness is possible using a separately combined transducer.
Distinctive parameters of the device
- Significant expansion of the device’s functionality through the use of two different types of converters.
- A lithium-ion battery is used as a power source. It is charged using a standard USB interface or the included network adapter.
- An automatic system for adjusting the surface quality of the measured materials first began to be used in A1208 ultrasonic thickness gauges. It has no analogues and allows you to get the most accurate results when measuring products of small sizes or having traces of corrosion. In this case, additional manual tuning is not required.
- A large diagonal display on the TFT-matrix displays a high-quality image.
- Tool calibration can be done at the workplace and does not cause any difficulties.
Equipment features
The use of two types of sensors allows you to expand the optional capabilities of the device. Processing and subsequent saving of the measurement results can be carried out by connecting the thickness gauge to a personal computer via a USB interface.
The description of the A1208 ultrasonic thickness gauge indicates that the device is resistant to low, high temperatures and sudden jumps. The device is equipped with a high-definition TFT-display and a Li-Ion rechargeable battery. The device memory can simultaneously store up to 50 thousand measurement results. A high-precision device is designed to determine the wall thickness of plastic, metal products with a high level of attenuation of ultrasonic waves. The range of measured thickness is from 0.8 to 300 mm.
The ultrasonic thickness gauge can be synchronized simultaneously with separately combined and direct combined transducers. Connecting additional sensors extends the functionality of the device and allows you to determine the thickness of metal products coated with a paint or plastic layer.

Thickness Gauge Modes
The manufacturer provides for several modes of operation of the A1208 thickness gauge. So, each owner will be able to choose the appropriate mode for himself. To determine how they differ, it is necessary to characterize each mode.
Strobe mode
It is used to limit the controlled area. It is included in situations where, for example, it is required to determine the deviation of the metal thickness from the tolerance during the control of sheet metal. Auxiliary options: vibration, sound notification. They simplify and facilitate the work with the device. If the measurement results deviate from the tolerance, a warning signal sounds. The scale of the thickness gauge is presented visually on the display of the device. The operation of the vibration and sound indications can be set in the menu.
Memory Mode
The mode of operation designed to quickly determine the thickness of the material with the subsequent entry of the results in the non-volatile memory of the device. Up to 50 thousand measurement results can be stored in memory at the same time. The memory mode allows you to group the results, which is very convenient when the operator is working on various objects. The quick viewing and saving of the results is organized in a clear, logical and visual way: the thickness gauge displays the number of the cell into which the results will be entered, the previous measurements are also saved there. Previous recordings can be modified and overwritten if necessary.
Normal Mode
It allows not only to determine the thickness of the product, but also to evaluate the ratio of the result to a certain interval and the criterion for the operation of the ASD - automatic signaling of a defect.
- The introduction of the upper limit of the thickness in the form of 100% and the lower one in the form of a reject rate allows all measurements to be carried out with a simultaneous indication of the thickness of the test object as a percentage of the value set in the settings.
- Deviations of the results from the limits of acceptable values are accompanied by vibration, color and sound indications.
- The scale of the thickness gauge is clearly presented on the display of the device.
Tolerance Mode
It is used to quickly measure the thickness of products and determine the deviation of the obtained results from the set nominal values. This mode is most often used in cases where the permissible deviations are given in the regulatory documents.
- The measurement results are displayed on the screen of the device in the form of the difference between the real and nominal thickness of the investigated object.
- If the results deviate from the set parameters, an adjustment of the ASD response range is possible.
- If the measurement results deviate from the permissible values, the operator is notified through vibration, sound and color displays.
- Graphical measurement scale.
