Recently, Jiangnan Industrial Group Technology and Technology Research Institute successfully developed the DZC-9 type pyrotechnics resistance measuring instrument, and the fire resistance resistance testing technology has achieved new breakthroughs. The new measuring instrument is a special instrument for measuring the resistance of pyrotechnics. The biggest feature is the use of two-way comparison test technology, can work between -40 ° C ~ +55 ° C, the test current is 1 mA, can ensure the resistance measurement accuracy of one thousandth, the resolution reaches 0.1 milliohms. The product resistance measuring instrument has been in the company for 30 years of research and development history, Hunan provincial labor model, Jiangnan company chief expert Yin Bo has been committed to the research and development of the project. Since 1988 produced the first DZC-1 type fire Since the work resistance measuring instrument, Yin Bo has persistently researched and explored, and has created the 'two-way DC current measurement method', 'AC square wave measurement method', 'two-way comparison measurement method', breaking through the primary battery between dissimilar metals. Potential difficulties such as potential, thermoelectric potential and other directional interferences on weak signals, and the development of measuring instruments from DZC-1 to DZC-9.
These measuring instruments not only ensure the production and scientific research needs of the company in various periods, but also meet the requirements of high precision, high safety and wide temperature range measurement of pyrotechnics in many fields such as aviation, aerospace, ship and military.
