InBeijing Huairou Science Citya400-plus square meterconstant temperature and humidity laboratory has passed acceptance. The laboratory relies on the environmental control system independently developed by Nanjing Expansion Technology Co., Ltd. to achieve temperature fluctuation±0.05℃, uniformity ±0.1℃ofprecision,creating the necessaryhigh-precision constant temperature and humidity laboratory environment.

As a high-tech enterprise specializing in laboratory environmental control for26 years, Nanjing Expansion Technology has built constant temperature and humidity laboratories for 31 provinces and cities across China, and over 1000 scientific research institutions, universities, testing and inspection institutions, and enterprises.In a national-level metrology institute project, the implementation area is nearly3000㎡，among which the high-level gauge block laboratory temperature requirement is20±0.2℃; the gauge block measurement laboratory temperature requirement is 20±0.3℃; the nanometer measurement laboratory cleanliness requirement is 10,000 levels, and the temperature requirement is 20±0.5℃; the ultra-high precision three-coordinate measurement laboratory temperature requirement is 20±0.5℃, temperature change 0.2℃/h, and temperature gradient is 0.1℃/h. In addition, this project also focuses on the interference (mainly vibration and electromagnetic interference) that may be caused by laboratory and park power (HVAC, electricity, etc.) and large equipment, such as vibration prevention and foundation, and reasonably arranges the layout according to the characteristics and requirements of different laboratory equipment to minimize the potential impact and interference in the later stage。

Facing the three major technical barriers in the construction of ultra-precision constant temperature and humidity laboratories——environmental disturbance isolation, dynamic balance control, and long-term stable operation, Nanjing Expansion Technology has formed a unique technical system。"Modern scientific research's demand for constant temperature and humidity laboratories has shifted from macroscopic control to microscopic stability." The technical director said when introducing a case of a new energy storage material laboratory, the laboratoryrequires maintaining a constant temperature of 25±0.005℃ and a constant humidity of 45±0.5%RH throughout the year to eliminate environmental variable interference in material phase change testing。In an application of a semiconductor packaging enterprise, the Class 1000 clean constant temperature and humidity laboratory built by Nanjing Expansion Technology has increased product yield to99.97%.

Nanjing Expansion Technology in the construction of constant temperature and humidity laboratoriesfieldhas persisted for 26years,Its co-authored "Engineering Technical Regulations for Constant Temperature and Humidity Laboratories", "Calibration Standards for Environmental Parameters of Constant Temperature and Humidity Laboratories", and other 10 industry standards have covered key technical fields such as constant temperature and humidity laboratories, clean laboratories, biosafety laboratories, physical and chemical laboratories, and laboratory energy saving校准规范》等10项行业标准已覆盖恒温恒湿实验室、洁净实验室、生物安全实验室、理化实验室、实验室节能等关键技术领域It is the firm choice of more than 3000 laboratory users.
