Measures up to three gases
November 1st 2003 A new range of multi-component laser-based gas measurement instruments from Casella ETi simultaneously measures up to three different gases, including CO, CO2, HCI, H2O, NH3 and HF, and combines acid gas and moisture measurement in situations where all gases have to be reported on a dry gas basis.
The NEO laser gas system embraces a multi-scanning technique that enables the tuneable laser system to measure high temperature oxygen to 1500C, while still being able to calibrate the instruments to lower temperatures.
Normal process air may be used to keep the optical windows of this non-extractive cross duct free from fouling without interference to high temperature measurement. More articles from Casella Measurement: |
