This Model OGH180 Advanced Protocol model provides the necessary technologies for users requiring ultimate accuracy and increased heating capability up to 330°C. From simple drying of glassware to the most complex and carefully controlled heating applications, your oven is an invaluable part of your daily work. The Thermo Scientific Heratherm oven is backed by a two-year warranty on parts and labor, meaning confidence for your investment. Surpassing energy efficiency, increasing cost effectiveness, reducing environmental impact. Timer for effective usage and additional energy savings. Flexible shelving system allows for optimal space utilization. Routine check upon startup for optimum performance levels. Automatic audible and visual overtemperature alarm. Access port for data logging with independent sensors. Low surface temperatures. Easy to read, large display. Easy setting with intuitive interface. Easy cleaning with rounded corners. Unique door design reduces heat emission significantly. Additionally, the door can be opened 180° to allow convenient access to the interior for hassle free cleaning and easy loading of probes. Includes RS232 data interface. cCSAus certified. A sophisticated timer extends your options: you can automate the oven to turn on or off after a pre-set time, choose between a recurring weekly timer or run oven based on the 24 hour clock. Highest level of temperature uniformity. Exceptionally low energy consumption: 60L model needs just 170W (gravity convection) or 275W (mechanical convection) to maintain 150 degrees. Adjustable fan speed. Access port allows the introduction of sensors for independent data monitoring. Gravity convection offers gentle drying and heating with low air turbulences; perfect for materials that are sensitive to airflow such as powders and foils. Convection technology: Gravity.
