NDIR DLCO Gas Sensor for Pulmonary Function Test
Gasboard-2051Gasboard-2051

Gasboard-2051 gas sensor for CO, CH4 and CO2 concentration measurements which is based on non-dispersive infrared technology,it uses an ultra-fast modulation frequency and a special detection circuit to achieve the fast response, high accuracy, excellent stability and anti-interference abilities during lung diffusion function tests. With microcontroller processing, it offers gas sampling, signal processing, sensor calibration and measurement output, and realizes the fast and accurate measurement of the ultra-low range gas CH4, CO based on the ATS/ERS 2017 requirements. With small size and clean design, Gasboard-2051 is the best choice to be integrated with pulmonary function test systems.
