Product Introduction:
The LH600 CO2 sensor is the ideal low sampling-rate capnography solution for your patient monitoring system. LH600 can show an accurate capnogram with all respiration rates up to 120 breaths per minute. Cutting-edge technology enables LH600 to provide accurate measurement of instantaneous CO2 concentration, respiration rate, end-tidal CO2, inspired CO2, inspiration time and expiration time. With a sampling-rate low to 50 mL/min, LH600 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 and CPT module
