The Criterion temperature/humidity chamber series provides an economical and space-saving solution for a variety of testing requirements.
Wide temperature range from -70ºC to +180ºC
Lowest temperature: -20, -35, or -70°C (-4, -35, or -100°F)
Highest temperature: 180°C (354°F)
Faster change rate (heat/cool) up to 5°C/min.
The Criterion series can cycle temperatures at a rate of up to 5°C/min. without requiring liquid nitrogen. Significant test time can be saved, as well as creating added thermal stress on your samples. To demonstrate performance, ESPEC uses the international standard IEC 60068 3-5 measured at the supply air. Temperature cycles are run from hot to cold extremes, and the middle 80% of the transition is timed to determine performance. Your actual cycling results will vary depending on methodology, including the start and end temperatures, and the amount of samples loaded.
Chamber sizes: 1.5 or 4 cubic feet
Fully programmable with Watlow F4 controller
The extended temperature ranges of the Criterion series make testing at extreme conditions possible without buying a larger, stand alone chamber. Two chamber sizes are available, as well.
The programmer includes a temperature alarm as just one part of ESPEC’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.
Six models, two sizes: 1.5 and 4 cubic foot
Wide temperature range: up to -70 to 180°C
New model with 5°C/min. change rate
Interior is 3.5” wider than competitors
Space-saving design
