Klein Electrical Test Kits

Durable, Compact, Reliable, Easy to Use

The CL220VP Premium Meter Electrical Test Kit from Klein Tools is designed with optimum reliability and safety in mind. The kit comes with 1 clamp meter and 3 testers for a variety of applications and all stored within a convenient padded pouch. The CL220 is an auto-ranging 400 Amp clamp meter that measures AC current, AC/DC voltage, and temperature. The NCVT3P is a dual range non-contact tester with an integrated flashlight for a broad variety of voltage applications from 12 to 1000V AC or 70 to 1000V AC. Test AC and DC voltage at four commonly used ranges with the ET40 Voltage Tester. The RT210 Receptacle Tester detects common wiring problems for Standard and GFCI AC electrical outlets.
