Product Introduction 
The Constant Temperature and Humidity Chamber series uses microcomputer single-chip control technology. Precise temperature and humidity control is achieved through an imported temperature controller and humidity sensor. The refrigeration system uses an imported compressor, and humidification is accomplished via an intelligent atomizer. The device features programmable control, supporting multiple parameter settings and adjustments. Temperature and humidity values are displayed directly on a dual-screen high-brightness digital display for convenient and intuitive operation. The working chamber is made of stainless steel, with a cold-rolled steel outer cabinet finished with electrostatic spraying. A large-view insulated vacuum tempered glass observation window allows easy monitoring of sample conditions inside. Shelves in the chamber can be freely adjusted in height and quantity according to user requirements.

Main Technical Specifications 

FAQ 
1. What industries and tests is the chamber suitable for?
It is suitable for sterility testing and stability checks in pharmaceuticals, textiles, and food processing, as well as raw material performance testing, product packaging testing, and product life testing of industrial products that require precise temperature and humidity environment simulation.
2. Can the temperature range of 40℃ to +100℃ be expanded?
The standard temperature range is 40℃ to +100℃. For lower temperature ranges or other special temperature intervals, please consult our technical team for customization options.
3. How are the shelf height and quantity adjusted?
Shelves in the chamber can be freely adjusted in height and quantity according to user needs to accommodate the placement of samples of different sizes.

4. Why is vacuum tempered glass used for the observation window?
Vacuum tempered glass provides excellent thermal insulation and visibility, effectively reducing heat loss from the chamber while allowing operators to monitor sample conditions inside at any time without opening the door, thereby avoiding temperature and humidity fluctuations.
5. What is the function of the standard illumination lamp? Can it be replaced?
The illumination lamp illuminates the interior of the chamber for sample observation. The standard configuration includes an illumination lamp, which can be replaced with a sterilization lamp for disinfection purposes upon user request.
6. Does the equipment require regular maintenance?
Keep the equipment clean daily, periodically check the water level in the humidification tank, and replenish water as needed. The imported compressor and core components are factory-adjusted and generally do not require frequent maintenance. If abnormal operation is observed, contact our after-sales service for inspection.
