HZR of Runfengyuan is a big brand of antistatic instruments. Our company bought a batch of their non-contact static voltage testers, so we don't have to worry about the quality and performance of the products. They have high requirements on product quality, and their product performance is constantly updated and improved. Their products have to undergo a lot of tests before leaving the factory, and the prototype has been tested before production. Only after the adjustment will I go to the production line, and I still feel very good.
