Guangzhou Electrical Testing Instrument Factory was founded in 1993. It is a professional manufacturer of various high-precision strain gauges and strain sensors. It has a modern factory building and a purified production environment and has introduced advanced equipment, instruments and instruments.

The main products include 15 series and more than 1,320 varieties of resistance strain gauge; four series of more than 300 varieties of weighing, force measurement, pressure and torque sensors. The weighing range is as small as 10 grams and as large as 50 tons; and there are high, medium and low temperature sensors suitable for use in various harsh environments, with temperatures of -30℃~+300℃ to choose from. These products are widely used in aerospace, medical care, chemical fiber, petroleum, machinery, energy, transportation, construction and other fields. The products are exported to more than 20 countries including Southeast Asia, Europe and the United States, with an annual foreign exchange earning of more than 6 million US dollars. It is one of the largest manufacturers of strain gauge and sensors in the world.

The company covers an area of ​​more than 31,000 square meters, has strong technical strength in the factory, with more than 80 technical backbone personnel of various types and more than 800 technical workers of the grade. Mainly produces 320 sets of various testing equipment and testing instruments (sets), of which 3 are high-precision testing equipment for national cycle verification, 5 high-precision laser welding machines, one laser marking machine, and multiple sets of production lines are equipped with Advanced microcomputer fully automatic detection device, automatic recording, automatic calculation, and automatic drawing. Organize production strictly in accordance with international recommendations OIML and the US NTEP international product standards. These provide solid software and hardware guarantees for extensive testing of quality.

The company adheres to the policy of combining self-development and introduction, and has successively introduced cutting-edge technologies and equipment from the United States, Germany, Japan and other countries. The company has developed a number of high-precision resistance strain gauges and strain-type high-precision sensors. At present, Guangzhou Electrical Testing Instrument Factory has developed into one of the domestic enterprises with relatively complete varieties and specifications and larger production scale.

Since 1999, the annual output value of Guangzhou Electrical Testing Instrument Factory has increased by 100% every year. In order to meet the demand for the continuous expansion of production scale, in 2004, Guangzhou Electrical Testing Instrument Factory invested 38 million yuan to establish a Zhuhai Guangtest product research and development and production base in Zhuhai, which brought the production conditions and production scale of Guangtest to a new level.
