Benchmark Scientific H3550-180-E Benchmark ST-180 CO2 Incubator, 180 Liter, 230V with Three (3) Shelves features unique and proprietary heat distribution technology, and provides the highest levels of temperature accuracy with minimal fluctuation (within 0.1°C). The six-side heating system, in combination with a low speed internal fan, uniformly spreads air throughout the chamber (without air exchange from the external environment). The chamber walls are constructed of high grade (316) stainless-steel, and all corners are rounded, preventing the accumulation of dirt/debris.
For added security, H3550180E features an internal alarm to alert the user if the CO2 percentage changes, or the temperature fluctuates by more than 1°C from the set point. In addition, a "quick-cal" calibration button allows for quickly adjusting the chamber temperature to match that of a properly calibrated external thermometer.
