The difference between constant humidity chambers (benchtop and vertical)


Constant temperature and humidity chambers can be divided into "benchtop" and "vertical" types. The main difference lies in the achievable temperature and humidity ranges. Vertical chambers can be used for drying at low temperatures and below room temperature, while tabletop chambers are only suitable for temperatures above room temperature and high humidity. In short, benchtop constant temperature and humidity chambers (also known as benchtop constant temperature and humidity test chambers) are essential testing equipment in aviation, automotive, household appliance, scientific research, and other fields.



The scientific name for a constant temperature and humidity chamber is "benchtop constant temperature and humidity test chamber," which is used to test the parameters and performance of products after changes occur in a constant temperature environment. It is mainly used to test the performance indicators of aerospace products, information electronic instruments, materials, electrical engineering, electronic products, and various electronic components under high temperature or humid conditions。The body of the constant temperature and humidity test chamber is processed and formed by CNC machine tools, with a beautiful and generous appearance and a novel design. The handle operation is convenient and without reaction force.

Vertical constant temperature and humidity chambers, also known as "programmable humidity-heat alternating test chambers," are used to test the performance of materials under various environmental conditions, assessing their heat resistance, cold resistance, dryness resistance, and humidity resistance. They are applicable for quality testing of electronic, electrical, mobile phone, communication, instrument, vehicle, plastic product, metal, food, chemical, building material, medical, aerospace, and other products.

These chambers feature high-precision temperature control (heating, cooling) and humidity control. They consist of two parts: heating and humidification. Air circulation within the chamber is achieved by a rotating fan installed at the top of the cabinet, balancing the temperature and humidity inside the chamber. Data is collected from built-in temperature and humidity sensors within the cabinet and transmitted to the temperature and humidity controller (microprocessor) for execution of programmed processes. It issues temperature and humidity control commands, which are carried out by the air heating unit, condensation tube, and heating-evaporation unit within the water tank.
