The 880-NSL uses field-proven, non-dispersive ultraviolet (UV) technology to measure H₂S and SO₂ concentrations simultaneously. A high-intensity pulsed xenon flash lamp directs UV light through a sample cell containing the gas mixture. Specific wavelengths—254 nm for H₂S and 280 nm for SO₂—are absorbed by the gas molecules. Precision optical filters and solid-state silicon photodiode detectors convert the remaining light into electrical signals. A microprocessor uses the Beer-Lambert law to calculate gas concentrations based on the amount of light absorbed. Measurements typically complete in about 10 seconds, with a very fast response time, reaching 90% of final value in under 15 seconds.

The distinct advantage of the Model 880-NSL is encoded directly into its acronym: . By utilizing an integrated, flange-mounted assembly that fastens directly to a process pipe, the unit entirely bypasses the primary failure point of traditional analytical configurations—clogged or frozen external sample lines. with a very fast response time
