Add a double protection program for water shortage in the evaporation furnace to prevent dry burning due to water shortage and improve the safety factor.
Increase the overpressure and pressure relief protection of the evaporation furnace to prevent the explosion of the bottle caused by the excessive pressure of the evaporation furnace caused by the failure of the solenoid valve, and improve the safety factor of use.
Automatically add and replenish water, and the amount of receiving liquid can be adjusted at will.
The water-saving function design can save a lot of tap water and advocate a new concept of energy saving, emission reduction and environmental protection.
The steam generator adopts an all-stainless steel electric heating tube to heat and control the water level, which is resistant to corrosion and durable, and automatically alarms when there is water shortage.
The specific integrated circuit control system can meet the safe use of different water quality in different regions, so as to ensure normal operation without replacing distilled water for a long time, save a lot of distilled water, reduce the cost of testing, and achieve the goal of fast, accurate and low consumption .
The anti-splash tube is formed of special high-performance acid and alkali-resistant heat-resistant plastic, with good sealing performance, stronger alkali resistance than glass, and long service life.
