Our heating mantles made of alkali-free glass fiber insulation material, the Cr20Ni80 alloy wire spring installed in them, with aluminum silicate cotton by the vacuum shape of the hemispherical insulation body insulation. Each mantle is made with extreme care and is hand sewn to assure its reliability, quality and safety. Maximum heat transfer to the sample is achieved by having excellent insulation around the cartridge and good flask coverage. All mantles go through the ‘burn off’ procedure at the end of the manufacturing process enabling use straight out of the box.
ZNHW-II type heating mantle added self-adjusting function, through which can make temperature rising faster and control precision more accurate. Temperature control use computer chip as main control unit, use multiple digital filter circuit, smart PID circuit control, single bond setting, fast temperature rising, low warm-stamping. Inside and outside thermocouple switch device can accurately display heating mantle’s temperature, and can accurately display the solution temperature in control flask after switching.
