Technosys Systems

GrindoSonic® MK7, the instrument for non-destructive measurements of Material Characteristics based on Impulse Excitation Technique (IET).

The GrindoSonic MK7 uses impulse excitation technique (IET) to non-destructively measure material characteristics. The universal instrument for industrial quality control and research purposes is equipped with Fast Fourier Transform (FFT) visualization.

Since a correlation exists between breaking load and natural frequency, the GrindoSonic MK7 is an alternative to destructive testing, with users receiving E- and G-modulus and Poisson’s ratio results in a fraction of a second from initiating measurement.

The system includes production process monitoring for launch and quality assurance/quality control and handles various materials in sizes from less than 100mg to 100 tons.

Included with the system is a piezo-electric vibration detector, acoustic vibration detector, a set of excitation devices, a reference test bar with test certificate, PC mouse, and a customized HPRC black case. Available options include frequency analysis, FFT calculation to detect multiple vibrations modes, choice of zones of interest by waveband filtering, oscilloscope function for time domain analysis, and graphic visualization of frequency domain.

Metal Spectrometer is used for inspection, quality control, and alloy identification. Many times  this is also called as metal analyzer. In Market Bench top and Portable both variants are available. In bench top most popular is OES Spectrometer and in case of Hand Held Portable Spectrometer X-Ray and LIBS Spectrometer Both are available. X Ray hand held analyzers are basically a PMI (Positive Metal Identification Machine). For more accurate metal analysis Optical Emission spectrometer is used.

Here we have association with a technology innovator company for India, this company manufacturing LIBS Spectrometer (Laser Induced Breakdown Spectroscopy). We have both Handheld LIBS Spectrometer for field use and also Online Spectrometer. This Metal Analyzer is more accurate than X- Ray PMI and also gives more number of Light Elements.

Our LIBS Spectrometer gives Carbon Value in ferrous base metal without use of any argon gas. Apart from Ferrous our machine works with Aluminum Base, Titanium Base, Nickel Base, Zinc Base and Copper Base. We are selling our spectrometer across India and also in neighboring countries.


Laser Based Portable Spectrometer is designed for operational incoming inspection of rolled metal, determination of steel grades, non-ferrous and ferrous scrap metals and alloys. The metal analyzer provides high speed in the determination of chemical elements: C, Be, Mg, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Sn, Sb, W, Pb and others.


Portable laser spectrometer is included in the State Register of Measuring Instruments under No. 85726-22 The principle of operation of Portable laser spectrometer

Portable laser spectrometeris based on the method of laser spark emission spectrometry. A short laser pulse turns a few micrograms of metal into plasma, the radiation is decomposed into a spectrum, and the intensity of the spectral lines determines the concentration of chemical elements.

Surface hardening improves the wear resistance and fatigue strength of dynamically stressed components. These functional characteristics are mainly determined by surface hardness, hardening depth and residual stress.

An essential quality feature of the surface hardening process is the thickness of the hardened layer (SHD). Currently, the hardened layer can only be tested in random samples using destructive methods, a procedure that is both costly and time-consuming.

Ultrasonic waves propagating in polycrystalline materials (steel) are scattered at material interfaces with changes of density and/or elastic properties. In general, the ultrasonic waves are scattered in all directions, one part also back to the ultrasonic transducer that generated the ultrasonic pulse. The intensity of backscattered ultrasound received by the transducer depends on the ratio of geometric size of scattering geometry to the wavelength of ultrasound and on the degree of material property difference at the interface denoted by the term acoustic impedance change.

In the regime where the ultrasonic wave length is large compared to the size of scattering geometry, higher ultrasound frequencies (or shorter wave lengths) increase the intensity of ultrasonic backscattering. Further, intensity of backscattering increases with the average effective size of the scattering geometry, for example the grain size of the polycrystalline steel. Using the appropriate frequency of about 20 MHz, the microstructure change between the hardened case (usually fine grained Martensite) and the core material with coarse grained microstructure causes a distinct increase of backscattering intensity. This effect can be observed when the ultrasonic pulse crosses the interface and standard time of flight evaluation yields the depth position of the interface that corresponds to the Surface Hardening Depth (SHD

Magnetic-eddy current flaw detector VID-345 is intended for detecting cracks and measuring their depth, detecting stress- corrosive cracks in metal ferromagnetic constructions, even under layer of corrosion and/ or protective coating.

Flaw detector enables to measure depth of corrosive damage as well as thickness of protective coating.

The device combines magnetic and eddy-current methods for flaws detection, which enables the user to control products with rough corroded surface and to measure through the layer of insulating coating of variable thickness without any additional readjustment.
