CRDS Laser-Based Analyzer
FOR EASY H2O ANALYSIS: 12 PPB TO 2000 PPM (IN N2)
For the first time, powerful advanced spectroscopy is available at a popular price for a host of applications, from quality assurance to cylinder filling, as well as welding, medical, industrial and high-purity gas production; bulk delivery and distribution transfer points; and more. Say goodbye to cumbersome, complex, costly and labor-intensive mid-20th century technology. Gone is the need for calibration, spare parts, cramped ranges, and worries about drift and downtime. The speed alone will make you gasp. Plus, it’s a joy to start-up and to operate.
