Sensor Compatibility
Most sensors are supported by G7, G8, and EXO. However, some sensors listed in the specifications — like hydrogen fluoride (HF) and ozone (O₃), are not supported by every G7, G8, and EXO variant.
The following table shows sensor compatibility with each G7/G8 and EXO variant.

1 H2 sensor is currently supported in North America only on G8.
2 H2 sensor is currently supported on G7 and EXO only outside of North America.
3 The A-CART only operates in pump mode, regardless of configuration.
