Műszaki információ: The antifreeze tester is a robust and shatter-proof measuring instrument with a very precise display that can be easily read at all cooling water temperatures. The compact dimensions mean that measurements in tight spots are no longer a problem. ? unsurpassed automatic temperature compensation with outstanding precision ? no measurement error if the instrument is not held vertically ? measuring chamber filled quickly without formation of air bubbles ? hydrostatic lock prevents any back flow ? Made from premium impact-resistant plastics, no metallic parts ? suitable for all ethylene-glycol-ethanediol-based antifreeze/water mixtures, at all temperatures ? suitable for G12, G12+ and G12++
