This Wewon’s 23 liters benchtop environmental chamber can not only perform temperature test, but also perform humidity test at the same time. According to different customers feedback, The 23L and 27L small sizes chamber are very popular with customers. In the last six months, Wewon Environmental Chambers Co., Ltd. has successively sold 8 sets of the same type of equipment to the US, Canada and Russia markets.
This 23 liters benchtop environmental chamber is a new product independently developed by Wewon Tech. Its key technology has applied for 2 national invention patents. This mini benchtop environmental chamber was unanimously approved by experts at the new product appraisal meeting of the Shenzhen International Semiconductor Exhibition in April 2019. It was identified as “The main performance of the product has reached the international advanced level.” Reactive polyurethane hot melt adhesive (PUR) has extremely high application value in the automotive, construction, machinery, electronics and other industries due to its excellent initial bonding strength, fast fixation, heat resistance, durability, and high final bonding strength.

High temperature alarm devices cannot be installed directly above the installation equipment. When installing the equipment, ensure that there is enough space for testing and heat dissipation of the equipment. There should be at least 60 cm between the machine and the wall and any other machines. The four corners of the equipment are equipped with fixed foot cups and rollers. When installing the equipment, a wrench can be used to adjust the surrounding foot cups to ensure that the equipment is level. When adjusting, use a spirit level to check the level of the equipment. When shifting, use a wrench to loosen the surrounding foot cups to move. equipment.
The Wewon’s benchtop environmental chambers can be raised or lowered by rotating the fixed foot cup. When positioning the equipment, use the feet to support the weight of the equipment. Before rotating the foot cup, use a wrench to loosen the lock nut. Move to the front of the equipment, adjust the foot cup so that the foot cup is off the floor, and then move the equipment. Sewage should not be directly discharged to the outside. The sewage pipe usually discharges the sewage on the main sewage pipe, or use a sewage collection container (the height of the outer edge of the sewage container is lower than the sewage outlet of the equipment, and the collected sewage should be dumped in time).
