Optical oxygen sensor Gasboard-2512

tunable diode laserTTLlong-life

Overview
Gasboard-2512 is a compact oxygen sensor developed for accurate oxygen measurement in medical applications. Based on tunable diode laser absorption spectroscopy (TDLAS) technology, Gasboard-2512 achieves ultra-high selectivity for accurate oxygen detection with excellent resistance to interference from other gases and moisture. It also delivers a fast response time, enabling real-time monitoring in dynamic environments.

With calibration-free operation, vibration resistance, and no maintenance requirements, Gasboard-2512 ensures long-term stability and maintains accuracy across variable conditions. Its modular design, low power consumption, and standard digital output enable easy integration into high-end ventilators, anesthesia machines, metabolism analyzers, and CPET systems for reliable, real-time oxygen monitoring in both static and dynamic environments.
