✔️ Measures ethanol and nitrous oxide concentrations from 0–1000 ppm
✔️ Infrared absorption principle ensures stable and repeatable results
✔️ High selectivity reduces cross-interference from other VOCs
✔️ RS232 interface allows reliable integration with diagnostic systems
✔️ Designed for continuous operation in clinical and research environments
✔️ Operates within 0°C to +55°C for standard field and laboratory conditions
✔️ Compact form factor simplifies integration into breath analysis devices
EtOH & N2O NDIR Breath Gas Sensor
The EtOH & N2O NDIR Breath Gas Sensor combines dual-analyte detection in a single infrared spectrometer, measuring ethanol from 0 to 1000 ppm and nitrous oxide from 0 to 1000 ppm simultaneously. Infrared radiation passes through the measurement chamber as breath samples flow in, and both molecular species absorb distinct wavelengths characteristic of their structures. Separate optical channels with wavelength-selective filters isolate each gas’s absorption signal, and Beer-Lambert law calculations convert absorption data into concentration values for both compounds.
The sensor communicates via RS232 serial protocol, allowing integration with diagnostic equipment and data logging systems. Operating temperature spans 0°C to +55°C, suitable for clinical and field environments. Internal configuration features a broadband IR source, dual optical paths with dedicated filters for ethanol and nitrous oxide, and independent detectors for each channel. This parallel measurement architecture delivers simultaneous real-time data without sequential sampling delays.
Military anesthesiology teams employ the EtOH & N2O NDIR Breath Gas Sensor in trauma care where patients may have consumed alcohol before requiring anesthesia. Navy medical officers use it aboard vessels to assess both pre-operative alcohol levels and anesthetic gas exposure during procedures. Airforce flight surgeons integrate these sensors into medical screening stations where pilots undergo fitness evaluations that check for substance use and anesthetic agent exposure.
Tactical Supply Pakistan delivers diagnostic instrumentation that streamlines medical assessments in resource-constrained environments. Their dual-parameter sensors reduce equipment redundancy while maintaining measurement accuracy. The company supports military healthcare operations with tools that address multiple diagnostic needs efficiently.
Can the sensor differentiate between metabolic ethanol and consumed alcohol?
The sensor measures total ethanol concentration in breath without distinguishing origin. However, metabolic ethanol from endogenous production rarely exceeds 5 ppm allowing clinicians to interpret results based on concentration magnitude and patient history.
