SBA-5 CO2 Gas Analyzer

Since 1984, PP Systems has partnered up with many OEM customers offering custom solutions that meet a wide variety of applications. Our SBA-5 CO2 gas analyzer has the enviable reputation for being high quality, reliable, stable, accurate, and versatile. It can be supplied on a printed circuit board (for easy integration into an existing system) or in a convenient, lightweight, rugged, anodized aluminum enclosure.

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.
