Gas Sensors

Qbit sensors for detecting trace gases adopt NDIR technology (Non Dispersive Infra Red). This technology is based on the measurement of optical absorption on some I.R. bands. characteristics of each individual gas. Qbit produces four lines of gas sensors: the LS series aimed at finding leaks, the E series for industrial or environmental measurements, the C series for gas purity analysis and the LV series for dynamic concentration measurements for biomedical applications. The LS and LV series gas sensors have been designed to achieve optimal sensitivity and response speed and are therefore not equipped with a reference channel. Consequently, they must be used by adopting a calibration procedure (background detection or measurement of background radiation). The E and C series sensors are equipped with a reference channel and can correct measurement disturbances linked to variations in temperature, pressure or relative humidity in the sampled gas, therefore they are suitable for measurements over long time intervals without the need for recalibration.

Serie LS

The LS series sensors are developed for gas leak detection for the industrial testing sector. They are typically used in instruments that operate by “sniffer” method by selectively drawing gas into areas …

Serie LV

The LV series sensors are developed for biomedical applications where it is necessary to measure a dynamic change in the concentration of a gas. To achieve maximum response speed …

Serie E

The E series sensors are developed for gas detection in closed rooms or near pollutant sources. They are designed for continuous detection over a long period of time and must therefore guarantee a good detection performance.

Serie C

The C series sensors are developed for fast and at the same time precise concentration measurement in gas-analysis applications. As they are designed for continuous detection of long duration …
