When we were children,our parents always warn us "Do comparison shopping before you buy",why they say like this?this is a very simple truth, for the first deal,we are always cautious, through continuous comparison in order to find out the best quality, service, after-sale and price. This apply to any industry,there are many manufacturers of environmental test equipment. When some customers inquire a temeprature humidity test chamber, they will find a very common problem. Why is the price of the same equipment quoted by the two manufacturers very different? 1, the chamber body process,which effects the exterior case quality,this price has a gap. 2, the components, esp.components of the refrigeration system, is the core value of the temperature humidity test chamber. 3, even if the body and refrigeration components are the same, some prices are different, that is the manufacturer technical level. 4, regional issues, Wuxi,Changzhou, Dongguan, these brands need to know more. 5. after-sales, a powerful manufacturer often with a sound after-sales service dept.. The above are both technical and service, as well as the delivery cost of goods to the local and overseas are different.

limatest Symor wants to tell you that humidity is not only the most important thing in the chamber, but also the temperature In order to facilitate customers to add water, our temperature and humidity test chamber is to place the water tank at back of the equipment.Just open the baffle to see the water tank and the water level meter next to the tank,then add enough water to the tank. However, in addition to manual water addition, our temperature and humidity test chamber has equipment that can automatically add water. Only by connecting the water pipe at the water filling port can it be automatically replenished when there is a shortage of water, which is suitable for high humidity test for a long time.

The temperature and humidity test chamber simulate the temperature and humidity, so there are a lot of things customers shoud notice in the process of use, although there is detailed instruction when purchasing the equipment. But some users just know how the device works and start using it. This is very easy to cause problems in the use of the equipment, so Symor intends to describe the safety details during the use of temperature and humidity chamber. 1. Before the test, determine if the sample contains flammable and explosive substances to avoid combustion or explosion during the test. Of course, also make sure there is no flammable and explosive material around the test equipment, otherwise it may cause fire and other accidents. 2, Do not open the chamber door to operate during the experiment, or the gas in the studio may cause the operator to burn and so on. 3. At the end of the test or at the time of regular cleaning of the test chamber, power off the equipment to avoid electrocution accidents. Also, when cutting off the equipment power, pull the power cord to pull out the plug, otherwise it may lead to a rupture of the power cord and so on. You can contact manufacturers if there are some places you donnot understand, do not dismantle and repair the temperature and humidity test chamber without authorization, otherwise it may lead to more serious problems.

It is necessary to know there are some faults that cannot be entirely avoided during the use of temperature and humidity test chamber, but how to deal with them in time is a problem that needs to be paid attention to.Here mainly explain the temperature and humidity test chamber compressor in the reason for the water, and how to deal with it. Reason: water comes from air, because there is always water in the air, known as humidity, which is compressed into supersaturated air and then analyzed to become liquid. The oil comes from the lubrication system of the compressor, possibly because the wear clearance of the mechanism increases, and the lubricating oil will escape into the cylinder. Solution: after the compressor is removed from the temperature and humidity test chamber, with a larger gas storage tank, the oil and water will naturally settle down to the bottom of the jar, and we need to discharge regularly to reduce the oil and water content in the compressed air. Of course, you can also use filters and other things to further reduce the content of oil and water. if you need to know more details about climatic chamber, keep an eye on our website www.climatechambers.com

Temperature and humidity test chamber has brought a lot of help to many industrial enterprises, but while it brings convenience to us, we should also take good care of them, otherwise they may be brought into the end-of-life phase ahead of time. The way of maintenance is also very simple. After daily use, the equipment is cleaned regularly, but the cleaning of the test chamber is also very skillful. If the operation is wrong, it may also lead to equipment failure. Let‘s learn how to extend the service life of the temperature and humidity test box together. 1, Pls clean the working room with water after each use, then dry the interior with dry cotton cloth. 2, Pls regularly remove dust from the evaporator inside the equipment, and periodically wipe the equipment to ensure clean and tidy. 3, When doing the test, the sample should be uniformly placed onto sample shelves,and the vent should not be blocked to prevent the influence of the test 4, It is necessary to pay attention to the cleaning of water tanks in peacetime, after the test or when the equipment is not intended to be used for a long time, all the water in the tank should be discharged, otherwise it will lead to the formation of scale inside the tank. The water used in the temperature and humidity test chamber must be pure or distilled water, or long-term use may result in a humidifier or internal pipe clogging. Above are the usual use notice of temperature and humidity test chamber, if customer adhere to the above several points,it is really able to prolong the service life of the equipment.
