Best For investment: Kleintools AC Auto ranging Digital Clamp Meter

Buy on Amazon

The kleintools ac auto ranging digital clamp meter's material feels more premium than its price would suggest. It has auto-ranging trms technology for accuracy. It measures AC current and ncvt via clamp and ac/dc voltage, resistance, frequency, dc microamps, capacitance, duty cycle, diode test, and continuity via test-leads, and temperature with thermocouple. It can only read dc current via the probes up to 200ma.

This must be geared towards AC electrical use. It includes a carrying case, test leads with cat iii/cat iv safety caps, thermocouple, instructions, and batteries. It defaults to ac for most settings so the SEL button must be pushed to switch to DC after turning the dial to position.

Why We Like This:

Includes a carrying case, test leads, thermocouple, and batteries
Made in the usa, sturdy, durable, and well made
Auto-range, data hold, and max/min value
Auto-power off after 10 minutes to conserve battery life
