Loop Resistance Tester Resolution: 1μΩ

The loop resistance tester is designed based on the latest electric power implementation standard of the People's Republic of China, DL/T845.4-2004, using high-frequency switching power supply technology and digital circuit technology. It is suitable for the measurement of loop resistance of switch control equipment. The test current adopts the DC 100A recommended by the national standard. The loop resistance can be measured directly in the case of a current of 100 A and displayed digitally. The loop resistance tester has accurate measurement and stable performance, and meets the requirements of high-voltage switch repair and high-voltage switch factory loop resistance test of power supply and power supply departments.


Features:

Using a high-precision, high-stability DC constant current source, it can provide 100A or 200A fixed DC current output, which overcomes the disadvantages of traditional circuit resistance measuring instrument to adjust the current output;

Loop resistance tester This product uses a precision instrument operational amplifier and high-precision A / D converter, combined with high-performance 16-bit microcontroller, the system automatically switches the magnification according to the signal size when measuring, to ensure the test accuracy of the product;

This product uses a wide temperature and backlit large-screen graphics liquid crystal display, rather than the traditional digital display or liquid crystal meter display, intuitive display of Chinese characters, making the instrument operation more convenient and simple;

Data storage and historical data browsing capabilities, can store 100 sets of data, and has power-down protection;

Built-in high-performance temperature sensor, automatic measurement of ambient temperature; can be equipped with high-speed thermal printer, output a complete test report.

Ultra-wide range, high stability, high reliability, cost-effective products.

Egg Crate Grille is a very economical solution to many lighting and luminous ceiling applications. These louvers are molded in polystyrene. The white panels are translucent and provide uniform illumination throughout the entire surface. Open cell design allows the light to be transmitted to the working area while reducing glare; in addition, this louver allows nearly unobstructed air movement which will increase the bulb and ballast longevity through more efficient heat dissipation. The louver is approved by UL for use under sprinkler systems and lighting ceiling applications.
