Model 311 and 611 Laboratory Incubators are designed to provide precise control and for this reason alone, it is fitted with a varied temperature range and an innovative digital microprocessor to display the parameters digitally. A membrane keyboard allows the operator to set the parameters. The device is devised to protect it from temperature fluctuations and there is a switchable turbo fan to control it. Two heating options are offered with the device - gravity convection and mechanical convection. In case of control failure in the primary control panel, there is a safety thermostat to protect the device and its samples.
