INCU incubator analyzer

The laws of thermal dynamics come into play, as well as the need to evaluate the temperature-control circuit operations sufficiently. It takes time for the incubator chamber to warm up (equilibrate) to the temperature control value set on the incubator controls. Once the chamber is at a uniform temperature (as evaluated by the four separate, but simultaneous, thermistor measurements), the temperature control-circuit operation can best be evaluated. It would be expected that the temperature be controlled within the accuracy band provided in the incubator manufacturer's specifications. This should also agree with the IEC Standard requirements. Shorter test durations may not catch faulty temperature control circuitry.
