Our products

Product category: Eddy current and magnetic powder testing equipment

Portable Systems

Technofour is not just about large automated Eddy Current Test systems. Several portable instruments are available for various applications.

The latest portable from Technofour is the World's first Android based touch-operated light weight instrumentEddyTouch.

Conductivity Meter Type 979 is used for measurement of electrical conductivity of non-ferrous metals in % IACS to within 1% accuracy. This digital readout instrument supercedes the old analog workhorse Type 757. Several hundred of which are still in active service.

A wide range of probes are available for use with these instruments and ultra-portables. These include motorized rotating probes for bolt-hole inspection etc.

Ultra-Portable Systems

Technofour have pioneered a novel concept in the form of credit-card sized Eddy Current and Ultrasonic instruments with USB or Bluetooth connectivity.

EddyUSB is a featherweight dual channel multi-frequency ultra-portable test solution for applications such as aircraft inspection for cracks and corrosion damage, material sorting, bolt-hole inspection, heat exchanger examination etc, besides being ideal for training purposes.

UTUSB is an amazingly capable Ultrasonic flaw detector sporting bipolar square pulser, active damping, tone bursts, DAC, TCG and a host of other latest features.

EddyBLU is the World's first versatile dual-frequency eddy current instrument with Bluetooth connectivity with Windows PCs/Tablets or Android phones/Tablets.

Metal Sorters

Technofour have a range of metal sorting equipment to cater to a wide variety of tasks. The top-of-the-line system is Multifect-GX, a simultaneous or multiplexed multifrequecy equipment for multiparameter inspection. It is a power-user system with several test modes, including Confidence test, Regression readout, Artificial neural network assisted sorting etc. Real-time Harmonic Analysis permits solving those difficult jobs where a lesser instument just does not cut it.

Multifect-EX (image) shares many of the features of Multifect-GX like multiplexed multi-frequency operation, Confidence tests, Regression readout, Automatic setup, Automatic sorting, Ethernet connectivity, Elliptical thresholds etc. It however misses out on Harmonic Analysis

World Class NDT Systems..
..At Down-to-Earth Prices

Fortyfive years ago, four green youngsters fresh out of India's premier engineering school, IIT Bombay, got their heads together and set forth on a daunting task. Their mission: to design and build a whole range of world class sophisticated Eddy Current non-destructive test systems.

Today the Technofour group takes pride in their products. Apart from arguably the best Eddy Current NDT systems in the world, the group has three other major lines of business: Highly sophisticated metal detectors for pharmaceutical, cosmetic, food and other industries; Check-weigher systems and mechanical handling systems and robotics.

Technofour have now diversified into Ultrasonic Flaw Detectors as well as Barkhausen Emission Analyzers. Technofour take pride in introducing the World's smallest credit card sized Eddy Current instrument - the EddyUSB, Ultrasonic flaw detector UTUSB and the World's first Bluetooth enabled instrument, the EddyBLU.
