The tunable diode laser absorption spectrometers (TDLAS) operate by measuring the amount of a laser light that is absorbed as it travels through the gas being measured. Because the sensor does not have contact with the process and there are no moving parts, maintenance is minimized, which decreases downtime and reduces the long-term cost of ownership (LTCO).
