CTC256 Climatic Chamber: Performance and Precision for Environmental Testing
The Memmert CTC256 climatic chamber is engineered to accurately replicate specific thermal and hygrometric conditions. It is used across various sectors where strict control of environmental parameters is essential, such as research laboratories, the pharmaceutical industry, stability testing, and quality control of sensitive components.
With a temperature range from +10 °C to +95 °C (with humidity) and active control of relative humidity from 10% to 98%, the CTC256 can simulate a wide variety of climatic conditions. Humidity is regulated by a hot steam generator, offering a resolution of 0.5% and a setting accuracy of 1%.
The control system is based on a microprocessor with self-diagnostic capabilities, ensuring optimal stability of internal conditions. Up to 40 temperature and humidity ramps can be programmed, each adjustable from 1 minute to 999 hours. Two Pt100 temperature sensors, using 4-wire technology, provide reliable measurement and redundancy for increased safety.
The chamber features a powerful electronically controlled air circulation turbine that automatically adjusts airflow based on operating conditions. Humidity and temperature levels are displayed via a high-precision digital interface.
The CTC256 is equipped with a heated door to prevent condensation, as well as a dual-compressor refrigeration unit operating with R449A refrigerant. Its 256-liter usable volume can accommodate up to six shelves, each supporting a maximum load of 25 kg. The interior is made of fully welded stainless steel (1.4301), facilitating cleaning and ensuring long service life.
The device includes a USB interface compatible with Memmert’s Celsius software for programming and data logging. It also features an interface for a PCL3-compatible inkjet printer, allowing documentation in compliance with Good Laboratory Practice (GLP).
Multiple safety features are integrated: mechanical thermal limiter, class 3.3 safety thermostat, audible and visual alarms, AutoSAFETY system with customizable thresholds, and fault detection via self-diagnosis.
Mounted on lockable casters, the CTC256 is easy to move while maintaining compliance with recommended installation conditions (ambient temperature between 16 °C and 28 °C, max humidity 70%, altitude up to 2000 m).
