1, electromagnetic measurement and analysis instrument
(1) electromagnetic measurement and analysis instrument development situation
Electromagnetic measurement and analysis instruments, including electromagnetic measurement instrument and electromagnetic quantity analysis and recording two kinds big. Electromagnetic measurement instrument including: installation type instrument, portable analogue instrument, a-digit and the following digital instrument (including portable), a-digit above digital instrument, precision instrument, the magnetic instruments and so on six classes; Electromagnetic quantity analysis and recording including: analogue oscilloscope, digital oscilloscopes, handheld oscilloscope, the other oscilloscope, a spectrum analyzer, the logical analyzer, recording equipment, accessories and parts.

Belong to the enormous quantity of wide product, is the basis for the development of all walks of life means and an essential tool, has been our electric instrument industry one of the advantages of the products.

Electromagnetic measurement analysis instruments including electromagnetic parameters measurement instrument and electromagnetic parameters analysis and recording, these two types of products from analog measuring technique is to the digital measurement technology transformation. Digital installed instrumentation, DMMS, digital magnetic field meter, digital oscilloscopes development is rapid, digital, systematic and intelligent and graphical has become the mainstream trend.

Electromagnetic parameters measurement instrument is electric instrument industry traditional products, it points with the instrument and laboratory with instrument. The meter must be great with dosage, and laboratory instruments used in occasions and relatively small. The dominant production is mounted instrument and portable instrument. Portable instrument main have a multimeter and clamp ampere meter. In recent years the development of to situation, portable digital instrument needs more and more. Traditional electromagnetic parameters measurement instrument is pointer type instrument, due to the rapid development of science and technology, digital instrument gradually entered the mainstream market. Installation type instrument and portable instrument belongs to monitoring or measuring instrument, the accuracy is not need high, the user to this kind of instrument is not very strong desire of digital degree, so long pointer type instrument always also share of the market. To install type instrument for, because digital power monitoring system gradually promotion, especially large and medium-sized industrial and commercial power users and public places for electric power load management device needs, digital installed instrumentation will be a lot of the market prospect.

1) mounted instrument
Mainly used for online monitoring power parameters and state instructions, in recent years in digital, intelligent, instrument use interface, standardization and serialization, generalization is a great development, ZhongDiDuan products in serious excess, but simulation of indicating meter intuitive and the trend shows is digital instrument is hard to replace, this also is simulated indicating meter in today will still be taking a market share is the main reason. With intelligent power grid construction of the deep gradually, this kind of product market demand will gradually decrease, it will be replaced by intelligent equipment (such as digitized substation), and these intelligent equipment reliability index is far higher than the traditional electromagnetic parameters measurement instrument, and this can lead to in the substation link installation type instrument in the use of decreasing year by year.

In order to cater to the change of market demand, digital installation type instrument is developing very fast, it not only have the electric parameters measurement functions, but also can realize to electric parameter analysis, diagnosis, control, protection, and take simulated output and standard communication interface. In order to adapt to different users of the installation structure and the characteristic, can divide embedded and guide rail type two kinds. In different applications, according to different function, can Jane but numerous, random combination.

With the increase of electrical parameters measurement, this kind of instrument is no longer only measurement instruments, has expanded to monitoring instrument, protects the meter, and widely used in electric power load management system (i.e., industrial and mining enterprises and building and energy management system) and electrical fire monitoring device. Along with the development of the national economy and promote energy conservation and emissions reduction, glue stickdigital installation type instrument will get bigger efforts to promote and application.

2) portable analogue instrument
Portable analogue instrument including multimeter, clamp ampere meter, ZhaoOuBiao, is a enormous quantity of wide tool, in national economic fields everywhere, especially in the industrial and civil multimeter has been applied in many fields, and is the product of mass production, is the basis for the development of all walks of life means and an essential tool, it is not only the traditional products and high-tech products, to increase quantity in recent years.

3) digital instrument
In recent years, China's digital instrument technology development soon, at present, China's years of digital multimeter can produce millions of Taiwan, especially the cheap digital multimeter produce about 80% of the world's total output, ranked first in the world. 2009 although the global economic crisis, but to export influence is not very big, year-on-year drop a few ten o 'clock. In 2010 the export of digital instrument has bigger to bounce back. But our high-grade digital instrument technology is developed and developing countries product difference, especially high-end products we still rely on imports.
