NuAire CO2 Sensor Circuit Board for Ultima II CO2 Incubator

The NuAire 030565 is a specialized replacement circuit board for the SPI-3N CO2 sensor system, specifically designed for the NuAire Ultima II series of CO2 incubators. As a 2015-era component, it serves as the primary control and signal processing interface for the incubator's infrared (IR) sensor, which is responsible for maintaining precise atmospheric conditions for cell culture.

Core Functionality

• Signal Processing: This board converts raw signals from the CO2 sensor into digital data that the incubator's main control system can interpret to trigger gas injection.

• Closed-Loop Control: It works in tandem with the incubator's microprocessor to ensure the environment remains at the user-defined setpoint (typically 5% CO2).

• Compatibility: Specifically engineered for the Ultima II cabinet series. It is a critical component for labs looking to repair older units rather than replacing the entire incubator.
