The Octagon 20 Advance incubator builds on decades of success of earlier  Octagon 20's with an all new intelligent design combining latest  digital and materials technology with Brinsea's 30 years of experience.  The result is an easy to use, accurate and high performance incubator  with exactly the right controls to give the hatching results you need. 
 
 The Octagon 20 Advance is also available in EX form which includes full  automatic control of humidity.  This flexibility and value mean the  Octagon 20 series remains the ideal choice whether you are breeding  macaws or geese, hens or peafowl.
 
 The specially designed control system is the heart of the Octagon 20  Advance. In normal mode it shows the incubation temperature and humidity  to very high levels of accuracy. A simple menu allows the user to  change the incubation settings. Features include high and low  temperature alarm and choice of °C or °F. The menu also allows full  control of humidity with the optional Advance Humidity Pump (see Octagon  20 Advance EX). 
 
 The high quality incubator cabinet is entirely injection moulded from  high grade ABS which makes it tough and easy to clean. The base is  double skinned and foam filled to reduce heat loss leading to lower  electricity consumption and better temperature distribution. The top of  the incubator is clear allowing good visibility of the eggs and chicks.
 
 Air is circulated by a long life computer grade fan which, coupled with  the unique grill with optimised air diffuser leads to extremely even  air temperature throughout the egg chamber. Fresh air is controlled with  a vent slider and humidity is provided by water in two reservoirs in  the base. 
 
 To accommodate eggs of different sizes the Octagon 20 Advance's  removable egg tray is supplied with dividers which the user can position  to suit their eggs and so maximise the number of eggs that can be held.  Eggs from as small as finches to as large as geese can be incubated and  a guide to the numbers of a range of popular species which will fit is  give in the specification table. Eggs are turned during incubation as  the whole incubator is automatically rocked from side to side every hour  by the Autoturn Cradle included.
