Product Introduction:
The PW-CSS10-40A SAFT Constant Temperature and Humidity Test Chamber is a tester designed for testing the anti-blocking properties of samples, assessing the holding power of pressure-sensitive adhesives, and conducting static load tests. In a simulated constant temperature and humidity environment, it automatically times how long the adhesive tape can remain under a specified load to determine the durability of the adhesive tape's adhesion. When the adhesive tape falls off the steel plate, the timer automatically retains the test duration, used to evaluate the persistent adhesion of the tape in high-temperature environments.
Test Applications:
Suitable for the holding power tests of various adhesive products, such as pressure-sensitive tapes, medical patches, self-adhesive labels, protective films, etc.
Product Features:
It can simulate various environmental conditions such as high temperature and high humidity, high temperature and low humidity, low temperature and high humidity, high temperature, and low temperature. It is equipped with easy-to-operate and learn high-accuracy programming controls to provide a testing environment.
Testing Principle:
The test plate with the adhered sample is vertically hung on the test rack, and a specified weight of weight is hung at the lower end. The resistance of the adhesive sample to pull-off is characterized by the displacement of the sample after a certain period or the time when the sample completely detaches.
Sampling Requirements:
50mm × 25mm (length × width)
Result Determination:
After a certain period, measure the tape's slide distance or the adhesion time.
Compliance Standards:
This instrument complies with multiple national and international standards: CNS-11887, 11888, PSTC-7, GB/T 4851, GB 4851, ASTM D3654, JIS Z0237.

Features:
Adopting the latest electronic expansion valve technology, it provides feedback on the detected temperature and humidity data of the test chamber to the temperature and humidity controller to control the opening and closing size of the electronic expansion valve, thereby controlling the output of refrigerating capacity, reducing the output of heating tubes, achieving water and electricity savings, effectively reducing energy consumption, and providing very stable temperature and humidity control. It is widely used in the fields of new energy and new materials.
The A-series energy-saving programmable constant temperature and humidity test chamber is a new model launched by Guangdong PW Instrument Co., Ltd. in recent years. It adopts imported compressors, paired with Japan's Saginomiya Electronic Expansion Valve, and is driven electronically through the controller independently developed by Yuelian Instrument, realizing control over the flow rate of the electronic expansion valve, thereby reducing the heating power of heating tubes and humidifying tubes, minimizing energy consumption, and effectively reducing water consumption during humidity testing, ultimately lowering electricity costs and costs for purified water. Through modular control technology, the refrigeration system is optimized for simplicity, lower failure rates, effectively controlling the phenomenon of high temperature or frosting caused by the return air temperature of the compressor, reducing compressor failures, and extending the compressor's service life. Under temperature and humidity testing conditions, the temperature and humidity are more stable, and performance is superior.
