Two types of drying oven structure and material introduction

图片
DHG and KH series of electrothermal constant temperature blast drying ovens are improved and optimized products based on the 101 series. Series 101 is used to transport air from the side, and the heating wire is at the bottom of the inner liner. The hot air heated during operation is forced into the left air duct by the blower and then flows to the inner tank through the punching plate. The loop is repeated. Because of the single side hot air circulation, there is no dead angle around the inner tank, The flow of air is difficult to cover, which causes the temperature difference phenomenon at different points of the inner tank.  drying oven The new modified DHG and KH have a great difference from the 101 Series in structure. The air duct is designed behind the inner liner, the blower is in the middle of the air duct plate, and the heating pipe is installed around the air blade as the center. The rotating air blade is drawn in the middle hole at the back of the inner liner and flows thr

How long can the constant temperature and humidity test chamber work?

图片
 The working time of the constant temperature and humidity test chamber can be set by itself. Taking the parameters of Kenton instrument LRH constant temperature and humidity chamber as an example, the timing range is 0~99 hours, 0~9999 minutes. Timing method: 0:0 ~ 9999 minutes; 1:0 ~ 99 hours; 0 to 59 minutes. Introduction to Operation Settings If: the equipment needs to start working after 10 minutes, the length of working time is 100 minutes. Operation and setting steps of constant temperature and humidity test chamber: Click the Set/Query key and switch the cursor to the value of the total period. Then the cursor stops on the value of the reservation time and changes the reservation time to 100 minutes. test chamber

These problems must be paid attention to in the use of electric drying oven

These problems must be paid attention to in the use of electric drying ovens . Take GX electric drying oven as an example. Clean the dust off the power plug and then insert it tightly into the socket. Dusty plugs or improper connections may cause a fever or fire. After a power outage or power cut, check the temperature, timing, and other setting values after restarting the equipment. Otherwise, the stored items may be damaged due to a change in the set value. When the equipment is not used for a long time after purchase, the equipment should be stored in a ventilated and dry environment. Otherwise, when you re-enable it, it may cause the device to break and not work properly. When handling the equipment, appropriate handling tools or personnel with handling qualifications should be prepared, and care should be taken not to let the equipment tip over to prevent damage to the equipment or injury to personnel. There should be enough width and height of the handling channel, if the need to

Can lab dishes be dried in a drying oven?

图片
In school and some hospital laboratories, drying ovens are often used to dry Petri dishes. Petri dishes are made of a flat, plate-like bottom and a lid, usually made of glass or plastic. Media materials are basically divided into two categories, mainly plastic and glass. If it is a plastic product, the highest acceptable temperature should be paid attention to. The drying oven temperature should be controlled according to the quality of the petri dish and the heat-resistant temperature. drying oven In the dry hot state, because of its poor heat resistance, microbial heat resistance is strong, needs to be heated for a long time, in order to achieve the purpose of sterilization. Therefore, dry hot air sterilization is usually at a higher temperature than wet hot air sterilization. In order to ensure the sterilization effect, the general requirements: 3-5h,135-140℃, 160-170℃, 2-4h,180-200℃, 0.5-1h. The temperature of the drying oven should be set according to the regulations. Do not ope

What should we pay attention to before the use of vacuum drying oven?

 The use of a vacuum drying oven is different from that of an ordinary drying oven. What should we pay attention to before the use of a vacuum drying oven? The following content is introduced by Kangheng Instrument. 1. The door handle pulls up and then pulls out to the right to open the outer door; 2. Hold the shelf with your hand, then pull the shelf horizontally out of the shelf can be moved; 3. Remove the shelf accessories inside the equipment, wipe the shelf with gauze, and clean the sealing ring of the inner liner mouth and the inner wall of the box body; 4. Put the shelf into the equipment according to their own drying or experimental requirements, then push the shelf horizontally inward to the appropriate position of the shelf, the shelf can be completed installation; 5. Connect the vacuum pump interface with the vacuum interface on the rear side of the oven body with a vacuum tube (user-provided); 6. Use if need to put the article when going up in the same shelf, want to put a

Humidification principle of constant temperature and humidity chamber

图片
The constant temperature and humidity test chamber are composed of a refrigeration system, heating system, control system, temperature system air circulation system, and sensor system. The above-mentioned systems are divided into two aspects: electrical and mechanical refrigeration. There are many ways to express humidity. As far as testing equipment is concerned, the concept of relative humidity is usually used to describe humidity. The definition of relative humidity refers to the ratio of the partial pressure of water vapor in the air to the saturated vapor pressure of water at that temperature. The saturation pressure of water vapor is only a function of temperature and has nothing to do with the air pressure of water vapor. constant temperature and humidity test chamber WS

What kind of drying oven is of better quality?

图片
Whether in the major e-commerce platform or in the search engine, many people will be more concerned about the quality of the  drying oven , many people maybe ask "Is the Kenton laboratory dry oven reliable or not reliable?" and so on a series of questions. Well, for this kind of question, in fact, the answer is more difficult to conclude. Because different brands, different businesses, and whether the quality is good or bad, can not be arbitrarily evaluated. However, you can measure the quality of a product from the parameters material, etc.. At the same time, the market, although now the homogenization is more serious, but choose a good brand or a relatively stable quality. Kenton laboratory Co., Ltd. is an entity specializing in the production of biological thermostat equipment and experimental laboratory, founded in 1999, after twenty years of development, has been relatively mature. There are agents all over the country, and products such as oven incubators, have entered

What should I pay attention to when using the oven?

The oven is the use of steam, electricity, far infrared, electric steam dual-use, make the object drying equipment. The most common type of oven on the market is electric heating oven, which is suitable for baking, drying and heat treatment in the range of 5~300℃ (some 200℃) higher than room temperature, and the temperature resolution (℃) is 0.1°C. It has many models, but the basic structure is similar, generally by the oven, electric heating system, and automatic temperature control system three parts. The use of the oven , the oven should pay attention to matters and use safety specifications drying oven GX 1, put the oven, oven, the equipment can not be put around the flammable and explosive items. 2, we should pay attention to the safety of electricity, the oven should be placed in the indoor dry and degree, to prevent vibration and corrosion to choose enough power wire, and there should be a good grounding wire. 3.
