Digital Clamp Meter


Industrial Use Rugged AC and DC/AC T-Rms Clamp Meters

DT-3390

Confidently take reliable readings with the DT-3390/DT-3391/DT-3395 Series of clamp meters. The Extra Wide Jaw easily clamps around large conductors, typically found in high current applications. The rugged design CAT-IV 600V, CAT-III 1000V ratings add an extra element of protection when taking high-powered measurements. The measurement of capacitance, temperature (not available in DT-3390), resistance and Frequency makes these this the most versatile tool for utilities, electrical contractors and industrial service technicians.
