▏Product Features

◎This machine adopts a 5.7-inch LCD vertical display with a large Chinese screen, providing clear and intuitive images. 10 temperature control values (column box 1, 2, injector) can be displayed simultaneously on the same interface

1, 2, 3, temperature set values and actual values for detectors 1, 2, 3, auxiliary 1, 2, etc., and reserved areas for fault alarm positions, time display areas, event areas, etc.

◎It can display the temperature, time, events, range rise, stopwatch, extreme temperature protection values of the instrument, and add status indicator lights, fault alarm lights, etc. on a universal basis

Integrating culture and convenience.

◎Having core temperature control development technology, PID temperature control system, utilizing the characteristics of bus development technology, adopting control chip, dual over temperature protection of temperature control software and hardware, enabling temperature control

The system runs for a long time, is reliable and durable
