Whatever your test requirements are, you'll find extra durability, extra dependability in Hoskins electric laboratory furnaces. Whether they're muffle, combustion or crucible type units, good insulation is provided for cooler operation. And . . . important . . . they're equipped with well-designed, long-lasting CHROMEL heating elements that stand up under plenty of hard, hot, continuous use. CHROMEL, you know, is the durable Nickel-Chromium Alloy that first made electrical heating practical. In use it takes on a thin, tight skin of oxide that serves as a protective coating against pro gressive oxidation. It's the vital part of every Hoskins furnace.
