The YNHM-3000 insulator ash density tester is a complete set of "ash density" measuring device developed by our company according to the needs of our country's power grid anti-pollution flashover work and in line with the new standard of grid pollution classification. The device complies with GB/T 16434-2004 "Selection and size determination of high-voltage insulators under polluted conditions Part 1: Definitions, information and general principles" (instead of GB/T 16434-1996, GB/T 5582-1993, JB/T 5895-1991) and State Grid Corporation Q/GDW 152-2006 "High-voltage overhead lines and substation environmental pollution area classification and external insulation selection standards".

YNHM-3000 Insulator Ash Density Tester is a complete measuring device. It includes components such as precision electronic balance, blast drying device, filtering acceleration device and measuring accessories. The whole set of device is easy to operate and accurate in measurement.

1. The filtration acceleration device has mature technology, convenient use and high efficiency. With multiple taps, multiple filtering processes can be realized at one time. Use water circulation device instead of oil circulation pump, which is more convenient to use and has low failure rate;

2. The blast drying device adopts German technology with excellent air duct; the fan has low noise and stable performance;

3. Microcomputer intelligent control, after setting the temperature, the meter will judge the power required for heating and display the heating status, the temperature control is accurate and stable;

4. Adjustable air inlet to control the temperature and gas discharge in the box;

5. The precision electronic balance has multiple functions such as digital multi-point linear correction, drift correction, power-on self-check and tare;

6. With supporting calculation software, the calculation is convenient and the result is more accurate.
