Programmable Temperature and Humidity Test Chambers
Temperature and Humidity Test Chambers provides an economical and space-saving solution for a variety of testing requirements. It can simulate different climatic conditions, such as heat-endurance, cold-endurance, dryness-endurance, and humidity-endurance, which defines the Performance of material. By testing the product under different climatic conditions to see whether its performance can meet the intended requirements. It is widely applied in the industries of electron, electrical equipment, vehicle, metal, food, chemistry, building materials, luggage, adhesion tape, printing, packaging, and other product components and materials.
The programmer includes a temperature alarm as just one part of Grande's Three-tiered over-temperature protection system. A thermal fuse and a user-set independent limit are also included. In addition, a specimen power terminal allows the user to safely operate powered equipment inside or with the chamber.
