SL diode laser gas analyser

The Sitrans SL diode laser gas analyser features an inline reference cell filled with a non-interfering reference gas, providing a non-contact measurement of gas concentrations in process or flue gases.

The analyser is suitable for process control in the chemical industry, process optimisation within the steel industry and as combustion control for boilers and municipal waste incinerators. It is also an effective device for measuring minimum or maximum concentration limits for oxygen in explosive-proof environments.

The analyser measures the specific light absorption of different gas components using light from a laser diode, which travels from the transmitter through the process gas to the detector on the receiver side.

All measurements are conducted on-line, providing a short response time for effective monitoring of critical processes.

The transmitter and receiver sensors are mounted directly on the process with no need for sampling systems. No calibration gases are required.
