Instrument introduction:

The vacuum drying box series produced by Yiheng Instrument has the characteristics of short heating time, accurate control, safe and reliable, and can smoothly dry heat-sensitive substances and easily oxidized substances. Yiheng Instruments is the only manufacturer in China that uses digital pressure sensors to automatically control the vacuum degree and vacuum pump through microcomputers.

Features:

● The rectangular studio enables maximum effective volume, and the microcomputer temperature controller is accurate and reliable.

● Tempered and bulletproof double-layer glass doors observe objects in the studio, and can be filled with inert gas.

● The box door is closed and tight and adjustable, and the integrated silicone rubber door seal ensures a high vacuum in the box.

● The studio is made of stainless steel plate material, ensuring the product is durable and easy to clean.

● Storage, heating, testing and drying can be carried out in an environment without oxygen or filled with inert gas without causing oxidation.

● Shorten the drying time, and reduce the drying time by more than 50% compared to traditional vacuum drying chambers.

Drying process control:

Vacuum drying process control can provide programmatic vacuum cycles, which can further shorten the drying time by setting the highest and lowest vacuum values ​​according to your requirements. For example: control the vacuum cycle through program and set the minimum vacuum degree of 50 Pa， Maximum vacuum degree 900 Pa， The cycles are 6 times, and the drying process is shown in the figure. As each cycle progresses, the humidity continues to decrease, the drying speed is significantly accelerated, and the maximum number of cycles can reach 99 times.

Cyclic program control function:

The user-friendly operation interface and programming program saves customer time and ensures reliable heating or drying processes. It can be programmed directly in the operation interface. It can preset 7 stages and 63 steps to program the program. Each stage has a set time of 1-99 hours and 59 minutes, and can preset the power-on and shutdown time.

Vacuum degree control:

Vacuum drying cabinets use digital technology to control the vacuum degree. "Manual control" has long been a thing of the past. Do you still think that the valves operated manually leverage accurately control the vacuum degree today in the 21st century? Automatically control the vacuum degree through digital vacuum gauge, providing you with more accurate and effective vacuum degree control. Through the panel, the vacuum degree can be easily controlled at 10 ~105Pa(Minimum vacuum level of 133 Pa)The control accuracy is ±1%。The vacuum gauge adopts a resistive silicon tube pressure sensor, which ensures a stable pressure value and is not affected by the air flow, and transmits the stable pressure value to the vacuum gauge.

Temperature control advantages:

It has 7-segment 63-step temperature programmable function: it has traditional program control mode, and can also set temperature and constant temperature time, which means "temperature" ~The temperature is constant temperature time” BPZ-LC It also includes slope mode program control, which should be defined in the "temperature-time-temperature" format: the time required to rise or fall from a certain temperature to another temperature, so as to accurately realize the rate control of the rising or cooling process. This makes it possible to control every process of heating up, constant temperature or cooling throughout the temperature experiment.
