Page 17: Features
Introduction LGA4000Z EXTRACTIVE 1.2 Features LGA4000Z Extractive Laser Gas Analyzer can be installed as an in situ component in a sample system. The analyzer features an organic LED (OLED) screen, which has the advantage of low power consumption, a wide angle of view, and enhanced low temperature operation (down to - 40℃). - Page 18 5. Low drift, less frequent calibration The LGA4000Z Extractive Laser Gas Analyzer has virtually no drift and excellent stability. Span drift has been determined to be ≤±1% FS over 6 months. Also, the time between calibration cycles is very long, reducing the overall cost of calibration.
