The VWR® Constant climate chambers with Peltier technology feature excellent variation and fluctuation values for temperature and humidity. They are energy efficient and environmentally friendly, with a low noise level, and they work almost vibration-free as no compressor is installed. These models, with forced air convection, provide a temperature range between 0 to +70 °C (max. 20 °C below ambient) and feature a stainless steel (DIN 1.4301) inner chamber and stainless steel housing, solid outer door and internal glass door. The PREMIUM models have an intuitive menu and user friendly software and a USB port with flash drive for data download to USB stick and for uploading programs. They can be connected to an Ethernet or Wi-Fi network for remote control from any computer, and users can receive notifications about selectable parameters via e-mail.
