The Microtemp antifreeze tester enables the antifreeze value to be determined precisely and is equipped with a 360° rotating twin measuring mechanism. A hydrostatic lock reliably prevents the liquid from flowing out and air from being drawn in. In addition, the patented suction system ensures bubble-free measurements. The matching suction hose is included in the scope of delivery. Compact and handy, the tester is ideal for use in the workshop and private sector.
