    The good nose for oxygen

    Measuring the oxygen in the process can be quite simple. The TRANSIC100LP from SICK is the rugged transmitter that uses Tunable Diode Laser Spectroscopy (TDLS) to measure O2 reliably. A technology more common in the world of high-tech analysis, is now being used in a field instrument: at an attractive price, easy installation, a long life, low-maintenance, and suitable for use in explosion-hazardous areas.
