The GYZJ-934-1 Barcol hardness tester imported from the United States is mainly used for rapid testing of the hardness of aluminum and aluminum alloys, glass steel, and other materials. The products comply with the United States standard ASTM B648-10 and national metrological verification regulations JJG610-2013 "A Type Bahia Hardness Tester, National Standard GB/T 3854-2005 "Test Method for Reinforced Plastic Barcol Hardness".
The GYZJ-934-1 Barcol hardness tester is an indentation hardness tester. It is quick and easy to test, and it can be a pressure. The effective test range is equivalent to 25-130 HB and can be used to detect pure aluminum and all aluminum alloys, including hard 2024, 7075 and other grades of superhard aluminum alloy. For pure aluminum, ultra-hard aluminum alloy, over-thickness, and unclampable aluminum alloy workpieces, the Barcol hardness tester is a good complement to the W-20 Vickers hardness tester.
10KW and above on/off hybrid system
This type system will be very big, wind turbine only or wind turbine with solar panels, on grid or on/off hybrid grid. It's very few to make off grid for this big system. Normally it will be used on commercial project, or farm, etc. However, if you want to make big power system, please provide us more information about your location, your wind and solar situation, your budget, etc, as more as you can, so we can design a system for you. We will choose suitable wind turbine and solar panel quantity, and controller, Inverter, also Energy Storage.
