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.

Grande Expertise in Humidity Control :
Controlling humidity in a small environmental chamber can be especially challenging. Grande expertise in humidity control brings intelligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance: An external steam generator allows expanded range and is easy to maintain. A separate de-humidification coil improves low humidity control and range. Wet-bulb humidity sensor is a “primary measurement method” for accuracy. It is also economical, easy to maintain, and reliable because it has no risk of failure due to over-saturation. (Read why analog is preferred over digital.) Direct water supply connection is standard, with options for water filtering and recirculating water tank. GRANDETOP® control software makes it possible to manage, monitor and assist the chamber anywhere, at any time, in multiple ways via the on board panel and desktop/mobile devices (WiFi, Ethernet, mobile network).The chamber wireless (WiFi) connection permits operation using tablets and smartphones (iOS or Android compatible).The operator interface can also be remotely accessed through a chamber connection to the customer's LAN or via mobile network (on activation of a SIM card data). It includes the 24 Hours interactive assistance system.
