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.

Volkswagen Golf 7 Carbon Fiber Car Seat Heater45Volks Wagen Car Seat Heating45Volks Wagen Alloy Wire Seat Heater For Car45Driving in a cold vehicle is never fun. But on a chilly day it takes some time for your engine heater to kick in, which means you have to live with the frigid conditions until the engine has a chance to warm up. Seat heaters are electronic heating elements that install into your seat giving your body warmth on even the coldest days. Unlike conventional vehicle heaters, seat heaters act quickly so there is no waiting around for a break from the cold. These heaters can be adapted to virtually any vehicle and are reasonably priced so that you do not have to pay a fortune for the simple comfort of some heat in your seat. we prefer seat heaters to conventional heaters not only for their fast operating times but also because you do not need to have the noisy and annoying fan blowing in order to feel the heat. If you frequent cold climates, seat heaters are a must have item.
