World-Class Quality and Performance

Wide-Range Selection

Affordable Price

In 2015, GW Instek celebrated its 40th year anniversary as the first professional test and measurement manufacturing company in Taiwan. GW Instek is well-known for its high quality, high performance at affordable prices and wide and range of Oscilloscope, Spectrum Analyzer, Signal Source, DC/AC/Supply/Load Power testing products, Basic Instruments including Electrical Safety Tester, LCR Component Meter, Mini-Ohm Meter and High-resolution Bench DMMs.



World-Class Quality and Performance:

Through the thorough environmental, safety, and accelerated life test of “products design phase” and strict production test, GW Instek takes prides in creating 40 years of satisfied customer experience throughout the world and GW Instek is considered the most reliable brand for professional instruments with lowest TCO-Total Cost of Ownership.

Wide-Range Selection:

GW Instek provides general purpose instruments such as Oscilloscopes (up to 500MHz), Spectrum Analyzers (up to 3GHz), Arbitrary Function Generators (up to 80MHz) that are benchmarked for better performance against several leading brands and provides great value to customers with respect to the price/performance.

Taking the GDS-2000E/GDS-1000B DSO Series of DSO for example, GW Instek created two powerful waveform processing platforms both enabled by the XINLINX Zync SoC; the GDS-1000B series with MSRP prices starting at less than US$400 can perform similar or even faster FFT characterizations of signals than that of many leading brands of DSO with MSRPs much greater (> US$3000) than GW Instek.

With respect to a “Power Testing Solution”, GW Instek provides AC Sources, DC Power Supplies and Electronic Loads with technology which is benched to those of Kikusui and Chroma to service the market segments of Automotive, LED lighting, Renewable Energy, DC motor and Switching Power Supply. Currently, GW Instek offers power ratings up to 1500W; however, GW Instek continues to invests in development at each of its R&D facilities in Japan and Taiwan and will soon produce instruments with higher power rating in the very near future.

Presently, GW Instek launches products that contain premium functionality such as component testing instruments in Electrical Safety (Hi-Pot - 500VA, 200VA, and 100VA power), LCR Component Test Meters (from 2K to 300KHz, 1MHz to 10MHz) and Hi resolution Milli-Ohm meters to service the needs and reinforce the strong presence in the Industrial market segment.

Affordable Price:

GW Instek defines VALUE to the industrial and education customer as continually investing in technology and moves to drive costs to more affordable levels without compromising product quality and premium functionality!

If one takes the PSW series DC Programmable Supply as an example, the PSW series has the features of CC/CV priority and variable slew rate adjustment to prevent the characteristics of high in-rush currents that you only find in higher power ratings or in high MSRP power supply.

Or even in the Non-programmable DC supply category like the GPS-X303 series, GW Instek is very serious to choose good quality transformers, cable, connectors and to conduct the design verification to make sure that GPS-X303 series delivers best quality with affordable prices for education and hobbyist!

Positioned as an economic alternative to high cost brands, GW Instek has from the beginning adopted a simple principle to offer Best-in-Class solutions when most customers who need equipment to get the job done and are constrained with limited budgets.

In Closing, GW Instek seeks a growth-partner relationship with customers around the globe.GW Instek’s mission is to deliver on simply reliable, high quality, wide-range of products at affordable prices for another “40” years.
