Mainstream EtCO2 Sensor, ETCO2 Monitor
Mainstream EtCO2 Sensor is a plug and play mainstream CO2 sensor for Clinical End tidal Carbon Dioxide Monitoring. adopts NDIR (non-dispersive infrared) technology for real time CO2 concentration, respiration rate, end-tidal CO2 value and inspired CO2 concentration . Its professional dewater method reduced disturb from the vapor.
PRODUCT FEATURES:
- Response is faster and less chance of erroneous
- Dual wavelength ,proprietary sample cell protects internal ndir components from contamination
- Barometer
- No pumping or pneumatic components to replace Maintenance requirements and overall cost-ofownership are minimized.
- No calibration required
- Compatible for Phasein IRMA/ HP Respironics CAPNOSTAT 5/CPT
- Private label option TTL/RS232,LEMO 8 pins/DB9
- Unique accessories & supplies for all patients
