The design of the SBA-5 ensures inherent calibration stability that has been confirmed by over 35 years of experience in gas analysis technology. The SBA-5 features a non-dispersive, infrared measurement technique coupled with microprocessor-based signal processing resulting in precise measurement of CO₂. Our innovative “Auto-Zero” technology and insulated, thermostatically controlled optical bench ensure fast warm-up, long-term stability, accuracy, and analyzer calibration. It also minimizes the effects of sample cell contamination, IR source aging, changes in detector sensitivity, and pre-amplifier gain.

The SBA-5 can be supplied with two different optical benches calibrated specifically to the range required. One bench is optimized for measurement ranges of CO₂ up to 30000 ppm and another for ranges above 30000 up to 100000 ppm. For users that want to recalibrate the gas analyzer to a new level, this can easily be achieved as long as it is within the range for that particular optical bench.

The SBA-5 is user-programmable making it a perfect solution for custom applications. Windows-based software (GAS) is also available for use with the SBA-5 for monitoring and logging sensor data.
