Safety rated up to CAT III 1000 V / CAT IV 600 V, the 2100-Delta is the ideal product for troubleshooting in industrial and commercial environments. Use it to check voltage, current, resistance, continuity and frequency, all in one instrument. Connect the test probes safely to the top of the housing of the instrument when testing for voltage, giving you an extra hand. The 2100-Delta simply checks current up to 200 A AC by sliding the fixed jaw around the conductor without the need to break the circuit. And like the 2100-Alpha, 2100-Beta and 2100-Gamma, the 2100-Delta is naturally equipped with reinforced components for dependable performance. It has an ingress protection degree of IP 64, is built according the voltage tester standard EN 61243-3:2014 and is GS approved.
