An incubator is a piece of equipment common to pediatric hospitals, birthing centers and neonatal intensive care units. While the unit may serve several specific functions, it is generally used to provide a safe and stable environment for newborn infants, often those who were born prematurely or with an illness or disability that makes them especially vulnerable for the first several months of life.This trainer is designed to demonstrate the operation, theory, repair and servicing of Laboratory Incubator equipment used at clinics & hospitals. The unit is given the fault diagnosis so as to facilitate the teaching of troubleshooting techniques. A fault simulator is provided with circuit block diagram of the device for students to study theoretically and experimentally in order to understand the operation of the device.
