The Model 726 Ambient Ozone Analyzer with Cal/Sample Valves

726 module

 

The Model 726 is a basic analyzer, like the 722, but includes a Cal/Sample valve that can direct either sample gas or calibration gas to the Equivalent Method Photometer. The valve can be switched either by external control via digital inputs or by internal timer control.

Installed in either Docking Station, the Model 726 is an ideal replacement for the Dasibi 1008.

Another version of the 726 is the 722V which is designed to be paired with the Model 724 in a Dual Docking Station, the 722V/724 combination instrument is an ambient ozone analyzer with an integrated ozone calibrator configured in a very compact package!
