SBA-5 CO2 Analyzer

Soil & CropsPhotosynthesis Chlorophyll & Respiration

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.
