Fast Temperature Change Rate Constant Temperature And Humidity Test Laboratory

Fast temperature change rate Constant temperature and humidity test laboratory Fast Temperature Cycling: 5°C, 10°C, 15°C or even 20 °C,30 °C/min Fast temperature change rate Constant temperature and humidity test laboratory has twenty different models which allows you to choose the size and performance best suited for your test applications. Temperature cycling rates from 5 to 20°C/min. are possible. Two different ultimate low temperatures are available: -40°C or -70°C. It requires the least amount of floorspace for this level of performance.. 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 ●P-300 touch-screen programmer for easy operation ●High performance, reliable Copeland Scroll compressors* ●Lower sound levels, even for air-cooled models (click on model numbers to see specs) ●One 4" (100mm) diameter cable port with flexible silicone plug ●Heavy-duty casters with adjustable feet for leveling unit ●Refrigeration gauges and hinged service panels for easy maintenance ●Non-metallic thermal break around the doorframe for thermal integrity ●Dew tray on the door to catch drips when opened ●Adjustable stainless steel shelf with heavy-duty support rails, supports 100 lbs. 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.
