Product Introduction: LH800 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 50 mL/min, it is ideal for use on adult, pediatric and infant patients; patients undergoing procedural sedation; and short- term monitoring of intubated patients. Product Features: 1.State-of-the-art Non-dispersive infrared (NDIR) technology, dual wavelength, no moving parts 2.Breath-by-breath CO2 monitoring 3.Sample rate low to 50 mL/min 4.Barometer pressure and temperature compensation 5.Range calibration in 0 15% by manufacturer 6.Fast warmup time ensures full accuracy within 5 minutes 7.oxygen, N2O and anesthetic compensation for accurate measurement 8.Low power consumption less than 2W 9.Fully compatible with Respronics Loflo sensor module Technical Specifications: Transducer Type | LH800 Sidestream CO2 sensor | Sample Rate | 50 mL/min, 10mL/min. | Principle of Operation | Non-dispersive infrared (NDIR) single beam optics, dual wavelength, no moving parts | Initialization Time | Capnogram displayed in less than 5 seconds Reaching full specifications within 10 minutes. | CO2 Measure Range | 0 - 114 mmHg 0 - 15% 0 - 15.2kPa | CO2 Resolution | 0.1 mm Hg 0 to 50 mm Hg 0.25 mm Hg 50 to 114 mm Hg | CO2 Accuracy | 0 , 40 mmHg ,2 mmHg 40 , 114 mmHg ,5% of reading | Respiratory Rate | Range 2 to 120 Breaths Per Minute (BPM) Accuracy 1 breath | Calibration | No routine user calibration required | Compensation | Automatic Barometer Pressure 400 - 800 mmHg.
