What Technofour does

Technofour is a privately held Indian non-destructive testing (NDT) equipment manufacturer founded in 1972 in Pune by four IIT Bombay graduates. The company designs and produces electromagnetic and ultrasonic inspection systems covering five NDT modalities — Eddy Current Testing (ECT), Ultrasonic Testing (UT), Magnetic Flux Leakage (MFL), Magnetic Hysteresis Loop (MHL), and Magnetic Barkhausen Emission (MBE) — and serves industrial manufacturers across primary steel, seamless and welded tubes, automotive, aerospace, defence, power generation, and petrochemical sectors. Its product range spans from portable field instruments (EddyUSB, EddyBLU, UTUSB) to multi-channel automated inline systems (PARAS-EX with up to 512 channels, Flawmark-GX, Magflux-EX), with proprietary signal-processing technologies including D3, real-time harmonic analysis, ANN-assisted sorting, and the VIRAT array probe architecture. GX-series systems include built-in OPC-UA servers for Industry 4.0 integration.

The company generates revenue primarily through one-time sales of configured NDT equipment, customized test automation systems (feeding units, sorting mechanisms, robotic manipulators), accessories and spare parts, and training services. Products are sold direct to enterprise customers via the company website and regional offices in North America, Italy/Eastern Europe, and North Africa; pricing is quote-based with no public disclosure. The company has no disclosed external funding, no subsidiaries, and no public listing. Strategic differentiation rests on the breadth of its NDT modality coverage, several claimed world-first product innovations (smallest credit-card-sized ECT/UT instruments, first Bluetooth-enabled ECT instrument), and a co-development partnership with CSIR-National Metallurgical Laboratory on the MagStar magnetic NDE device. Go-to-market relies on direct field sales supported by two decades of recurring trade show presence at Tube (Düsseldorf, Singapore, Moscow), WCNDT, and APCNDT exhibitions.
