2. Introduction 2.1 Product description The Laser 3 Plus is an advanced gas analyzer. It comprises a transmitter unit (TU) and a receiver unit (RU), with an optional AC to DC power supply, ancillary equipment and sample cell. The laser radiation detected by a photodetector is amplified and transferred to the transmitter unit through a multi-core cable which connects the receiver and transmitter electronics. The same cable transfers the required power from the TU to the RU. Connectors at each end of the cable, and a removable gland plate, allow removal of the TU and RU for calibration or maintenance....
