What is a constant temperature electrical heating sleeve?
ZNHW-type Electrical Heating Sleeve is used Alkali-free glass fiber as an insulating material, placed in a Cr20Ni80 alloy wire spring, a hemispherical heat preservation exosome shaped by vacuum with aluminum silicate cotton.
The shell is molded by one-time injection molding. The upper cover adopted electrostatic spray technology. Silicon-controlled output and has the protection function of a broken couple.
It has the characteristics of fast heating, high temperature, simple operation, and durable. It is the ideal instrument for precise temperature control and heating tests.
What are the product features of the constant temperature electrical heating sleeve?
ZNHW Type Product Feature：
• PID intelligent control, temperature digital display.• Switching internal and external converters, it can accurately display the temperature in an electric heating sleeve or solution in the bottle.
ZNHW-II Type Product Feature：
• A new self-tuning function is added based on ZNHW, the impulse temperature is small and the temperature control is more accurate.PTHW Type Product Feature:
• Adjustable pressure constant temperature, beautiful and generous style, easy to use.Technical parameters of Constant Temperature Electrical Heating Sleeve:
