Online Analyzers

LAS analyzers may be thought of as an atline “laboratory in a box” – complete with sampling, analysis, reporting/alarming, cleanup, and even auto-calibration for continuous, unattended operation.  And the LAS design is accomplished with minimum maintenance in view: for example, no peristaltic pumps are used and no pump tubing replacement is required!  In most cases, a quarterly PM is all that’s needed.
