Our sensors for trace gas detection adopt the N.D.I.R. (Non Dispersive Infra Red) Tecnology. This technology is based on light absorption at selected wavelengths for each different gas.
Qbit produces two lines of gas sensors: the LS series for gas leak detection and the 3G series for environmental measurements
LS detectors series
LS series gas sensors are designed for maximum sensitivity and speed they do not have a reference channel. Thus a calibration procedure (background detection) is needed with these sensors. Each sensor consists of an I.R. detection cell and an electronic board. The board is equipped with a micro-processor which performs the measurement and transmits it to any external control unit via an RS-232 protocol. For complete operations the sensor requires an RS-232 line, DC power supply (+/- 15 V) and connection to a suitable pneumatic circuitry to allow the gas being tested to flow into the cell.
We are ready to consider requests for gases that are not yet in this list of stock gas sensors.
