ZNHW-II smart digital display thermostat heating mantle use alkali-free glass fiber as insulating material, put Cr20Ni80 alloy wire inside it, keep warm by environmental protection material — aluminum silicate wool which has been vacuum case-hardened, one-time shell injection modeling, upper cover adopts static electricity spraying plastics process, spherical heating makes vessel’s heating area reach to more than 60%.
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.
