When purchasing a CO2 incubator, there are two types of heating structures to choose from: air jacketed heating and water jacketed heating. Although both heating systems are accurate and reliable, they all have their own advantages and disadvantages.
    The water jacketed carbon dioxide incubator maintains a constant temperature by enclosing the internal tank through a separate hot water compartment. The hot water circulates through the natural convection in the tank, and the heat is transferred to the inside of the tank through the radiation to maintain a constant temperature. The unique water jacket design has its advantages: water is a good thermal insulation material, and when it is powered off, the water jacket system can more reliably maintain the temperature accuracy and stability in the incubator for a long time ( The time to maintain a constant temperature is 4-5 times that of a gas-tight system). If your experimental environment is not stable (such as useful electrical limits, or frequent power outages) and you need to maintain stable culture conditions for a long time, then the water jacketed carbon dioxide incubator is your best choice.
The gas-tight carbon dioxide incubator heating system directly heats the gas in the tank through a heater in the tank. The air-sleeve design can quickly restore the temperature stability inside the box under the condition that the temperature caused by frequent switching of the door is frequently changed. Therefore, compared with the water jacket type, the air jacket type has the characteristics of quick heating and rapid recovery of the temperature than the water jacket type incubator, and is particularly advantageous for short-term cultivation and cultivation requiring frequent switching of the door. In addition, the air-sleeve design is simpler for the user than the water jacket type (water jacket type requires watering, emptying and cleaning of the water tank, and often monitoring the operation of the water tank). When purchasing a gas-filled incubator, it should be noted that in order not to affect the culture, the incubator should also have a fan to ensure the circulation and circulation of air in the tank. This device also contributes to the temperature, CO2 and relative humidity inside the tank. Rapid recovery.
Access Control Keypad is a security product that can be connected to a lock and unlocked by swiping card, password, fingerprint, mobile phone, etc. Residents can connect the access control keypad to the electric lock, magnetic lock, etc., and then control the door opening by access control keypad.
The access control keypad also plays a very important role in the whole intercom system. If there are multiple doors in the building and residents need to be controlled to open all doors.

The following is our access control keypad, which supports password and card swiping.
The following are its parameters for your reference:
1. metal shell, waterproof
2. Touch the button
3. 1000\4000 users
4. anti-flapping door
5.external card reader
