Hard Shell Carrying Case

The ATSI SST-450 Surge Suppressor Tester is designed to quickly and easily test all
commonly used transient voltage suppressors: metal-oxide varistors (MOVs), gas-discharge tubes (GDTs), silicon avalanche diodes (SADs), thyristor surge protective devices (TSPDs), and hybrid devices.
The tester's 1mA DC current source up to 1000 volts has both peak and average-reading detection to provide complete test parameters for both crowbar and clamp devices. Measurements are displayed with a 0.1V resolution.
The tester is capable of testing suppressors with a filtering capacitor up to 200uF.
