EziLab offers the Temperature Test Chamber EZL-TC154, a 420 L cascade climatic cabinet that drives products from -70 to 150 °C and 20 to 98 %RH. A two-stage R404A and R23 cascade with fully enclosed compressors and air-cooled condensing reaches -70 °C at an average 1 °C/min, while armored heaters under SSR control climb at 3 °C/min to 100 °C; fluctuation holds to ±0.5 °C with ≤2 °C uniformity and ±2 °C deviation. A programmable controller behind a color LCD touchscreen runs multi-segment profiles, with RS485, USB or LAN links optional for remote logging. The fully welded SUS304 inner tank measures 700 by 750 by 800 mm, and the 9 kW cabinet occupies 1.6 m² of floor. Aerospace and defense suppliers, automotive electronics makers, battery developers, semiconductor packagers, telecom equipment builders and third-party test laboratories use this temperature test chamber for qualification and compliance programs. Typical tests include cold starts, humidity soak, storage temperature limits, solder joint aging and sensor drift checks. Choose it over single-stage chambers when -40 °C is not cold enough for the specification. Humidity and cascade specifics sit on the Temperature Test Chamber page, and the benchtop and cycling siblings are gathered under Temperature Test Chambers.
