8pin Connector Sidestream ETCO2 Sensor CO2 Module LH800

Sidestream ETCO2 Sensor LH800

LH810 is an external plug and play sidestream co2 sensor. It does not occupy any host space and connects to host just with one eight-pin plug. LH800 features cutting-edge technology for measurement of instantaneous CO2 concentration, respiration rate, end-tidal CO2 concentration, inspired CO2 concentration, inspiration time and expiration time. It is generally used in patient monitor and anesthetic machine. With a sampling rate low to 50mL/min, it is ideal for use on adult, pediatric and infant patients; patients undergoing procedural sedation; and short- term monitoring of intubated patients.
