Benchtop lab gas analyzer
The Series 150-Lab H2S Analyzer from Analytical Systems Keco measures hydrogen sulfide without interference or “false positives” to provide highly accurate results. Other H2S analyzers on the market become easily confused in the presence of components that look similar to H2S and report false positives.
Used in inspection labs, gas terminals, the food and beverage industry and refineries, the Series 150-Lab H2S Analyzer is capable of high-precision gas measurement in the low, single-digit PPB to high PPM levels.
ASTM-approved, the H2S analyzer utilizes a colourimetric-rateometric tape method of detection unaffected by cross-sensitivities to avoid ‘false positives’ that cause negative results. In addition, the tape method analyzer never suffers from ‘zero drift’ nor requires a supply of zero air. As the Series 150-Lab Gas Analyzer only sees H2S, calibration models are not needed and the accuracy does not change even if the process does.
Other gas analysis methods require a continuous update of calibration models over time when processes change.
Easy to operate, operators only need to push one button to begin analysis after connecting the prepared sample to the analyzer through a 1/8th” tube fitting. (An optional Sample Cylinder with a regulator is available for high-pressure applications.)
Once “Start” is pressed on the keypad, the analysis is automatic. The sample is quickly analyzed by the H2S specific detector without cross-interference for quantitative analysis in ppb or ppm. The analysis time is fast – typically only five to ten minutes – without compromising precision.
Rugged, compact (10” x 12” x 6”) and lightweight (10 lbs.), the Series 150-Lab H2S Analyzer offers a cost-effective, reliable and user-friendly gas analysis method for process control, air quality, laboratory and product quality applications.
In addition, this ultra-precise benchtop gas analyzer offers various output options including RS-323 and 485 Modbus protocol. Units also interface with a data logger for data download to a PC. The gas analyzer offers an optional battery pack for operation in areas without a power supply.
