EDWARDS APG100 series Active Pirani vacuum gauges are available in two models. The APG100-XM is the standard model and measures to 10-3Mbar, the APG100-XLC is a corrosion resistant version with measurement to 10-4Mbar


Both gauges feature compact size for easy installation, a linear output
and a replaceable sensor tube. These gauges are compatible with all
EDWARDS TIC instrument controllers and other Active gauge controllers
and displays. They are also CSA,C/US approved as well as fully RoHS
compliant due to their lead free construction.
