The Thermo Scientific Heratherm Advanced Protocol Security Convection Oven OGH180-S combines the benefits of the Advanced Protocol line with an extra layer of security for applications where process reliability and security are essential. This gravity convection oven features an increased heating capability up to 330 C and provides the necessary technology for accuracy while offering additional safety protecting your most precious samples. Gravity convection gently dries / heats with low air turbulences and is perfect for working with materials that are sensitive to airflow such as powders and foils. An environmentally friendly design reduces energy consumption by as much as 20% compared to previous models and features a very small footprint ratio compared to the interior volume providing maximum space efficiency. The sophisticated timer extends automation options available to the user. Choose between a recurring weekly timer, run the oven based on the 24 hour clock or automate the oven to turn on / off after a pre-set time. The OGH180-S also features a lockable door for restricted sample access, adjustable fan control, programmable controller for temperature ramps / dwells, simple calibration routine, boost function for rapid heat up, 180 degree door opening for convenient interior access, simple microprocessor based touch button controls, large easy to view vacuum fluorescent display, an automatic overtemperature alarm system, RS232 data interface and a 2 year parts and labor warranty.
