Detailed Description

Criterion Temperature and Humidity Chambers  Criterion Temperature and Humidity 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. Features ●High performance and quiet operation (65 dBa) ●Space-saving footprint, designed for flush installation to wall ●Stainless steel exterior ●Full thermal break around doorframe ●One 50mm (2") diameter cable port on left, with flexible silicone plug ●Three levels of overheat protection, plus overcool protection ●Easy lift-off service panels, electrical access on left ●Detachable eight-foot power cord with plug ●Direct water supply connection for continuous operation (supply tank optional) Touch-screen programmer/controller with Ethernet ●Watlow F4T with touch-screen and Ethernet port standard ●Save 120 profiles with up to 1200 steps each (ramp, soak, jump, auto-start, end) ●One event relay for external device control, plus specimen power interlock relay for safety ●Grande exclusive options include: Web Controller for full remote access; Chamber Connect software for basic data logging and monitoring. USB and RS-232 ports available, as well.
