Step into nonstandard laboratory and help boost China Aerospace.

Through many selections, Linpin has become outstanding from the cutthroat competitions among lots of famous manufacturers in China and in the world and won the bidding. A group of low-temperature storage test chambers are ordered to be used for the storage of hydrogen-nickel batteries on shooting ranges and for activation tests within the activation time.

Simulate natural working condition to safeguard scientific research cause.

Our company has already cooperated with many branch institutions, directly affiliated units, co-construction units of Chinese Academy of Sciences and holding companies in which Chinese Academy of Sciences directly has invested, for nearly one hundred times. Shanghai Linpin Instruments Co., Ltd has already become the first choice of brand for environment test equipments of Chinese Academy of Sciences.

Environment test chamber provides facilities to educational units.

Linpin has years of experiences in cooperating with old schools with the history of a hundred years. Both parties have reaped in not only interests but also friendship and moving happiness. Linpin hereby wishes all teachers who are tireless in teaching students “foster students under the heaven and train talents throughout China”!

Attractive appearance ▪ High efficient and Easy operation

Constant Temperature and Humidity Test Chamber As one must-have test equipment for aircraft industry, automobile industry, home appliance industry and scientific research field, it can be used to test and determine the parameters and performance of electrical, electronic products and materials upon change of the temperature environment in high-temperature, low-temperature or constant tests.

Shallow groove humidification ▪ Special design and High efficient

Shallow groove humidification method
Humidifier control method: Contact-less equal-period pulse-width modulation, SSR (Solid State Relay)
Water level automatic compensation and water shortage alarming system
Humidity control introduces the same channel coordination control method of P.I.D + S.S.R system.

Top Facilities ▪ Ecology and Science

Refrigeration principle and compressor: In order to meet the requirements of test chamber on temperature decrease rate and lowest temperature, the test chamber's refrigeration system introduces the cascade refrigeration system composed of imported compressor, and boasts such advantages as reasonable matching, high reliability, easy operation and maintenance and so on.

Excellence ▪ Nuanced and comfortability

Seal: The double-layer high temperature resistant high-tension sealing strip between door and chamber of the equipment can ensure obturation of testing area.
Door handle: Introduce the door handle without counteraction for easy operation.
Feet wheel: High-quality fixable PU active wheels are installed on the bottom of the machine.
