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.

TSD Medium Thermal Shock
Large capacity, small footprint
ESPEC developed the TSD-100 with an interior of 710mm x 345mm x 410mm, while strictly limiting the overall size of the system. The footprint is reduced by 40%, as well as lowering power demand by 60% (compared to our ETS4-2CW model).
The TSD-100 chamber now includes a STT function. It monitors the specimen temperature using two sensors attached to the specimen and starts to count the exposure time, or proceeds to the next step once the specimen temperature reaches the preset temperature. This eliminates the need for pretesting, reducing the overall test time and ensures an accurate specimen temperature attainment. The specimen and test area temperatures can be recorded by connecting a temperature recorder.
