CSZ Environmental Chamber
A compact benchtop environmental chamber designed for temperature and humidity cycling. It provides a controlled environment (-68°C to +190°C) for evaluating the reliability and stability of small electronics, materials, and assemblies.
System Capabilities
The MicroClimate MCBH-1.2 utilizes a cascade refrigeration system to achieve extremely low temperatures (-68°C) while maintaining a compact benchtop footprint. It features a steam generator and refrigerated wet coil for precise humidity control.
It is equipped with the CSZ EZT430S touchscreen controller, allowing users to define complex multi-step profiles with ramps, soaks, and alarm limits for automated reliability testing.
Operating Modes
Constant Temperature
Holds a fixed setpoint for steady-state exposure and soak tests across the full temperature range.
Thermal Cycling
Automated ramping between temperature setpoints to simulate thermal shock and evaluate life-cycle fatigue.
Temp + Humidity
Simultaneous control of Temp and RH (10-98%) for accelerated aging and moisture resistance testing.
Programmed Profiles
User-defined sequences with up to 64 steps, allowing for complex reliability screening protocols.
