CRDS Laser-Based Analyzer
A SUPERIOR ANALYTICAL SOLUTION FOR YOUR HIGH-BRIGHTNESS LED NEEDS
Our Tiger Optics’ ALOHA+ H2O gas analyzer advances moisture detection in ammonia (NH3) to unprecedented levels. The analyzer provides specialty gas and High-Brightness LED makers with the exceptional detection limits, accuracy, reliability, speed of response and ease of operation. Our proven Continuous-Wave Cavity Ring-Down Spectroscopy based moisture sensors ensure the ammonia process gas is of the high quality necessary to produce High Brightness LEDs. This cost-effective analyzer is quick to install, easy to use and effortless to maintain. There are no offline periodic sensor maintenance procedures, no span calibrations, no purifier replacement and no pump rebuild required. Our ALOHA+ H2O analyzer is fully self-calibrating and the “bright” choice for your detection needs!
BENEFITS
