Best With Inrush: GTC Low Amp Clamp Meter

Buy on Amazon

Not everyone likes to purchase meter for their daily purpose, but the gtc low amp clamp meter would be an anomoly. It's a tester that has an ability to measure current as low as 1 mA. It is perfect for checking ignition off draws, checking blower fan amp draw. It is very useful for lower draws such as parasitic drains and small current. The electronics that measure DC current are sensitive to temperature fluctuations and the offset (zero value) will change as the instrument cools or warms.

It is quite accurate and very handy for current measurements. It is ideal for automotive and other dc related maintenance job. It's great for checking amp load in automotive testing, and works great.

Why We Like This:

Construction is solid and convincing to the user
Great for automotive and diy projects
Perfect tool for parasitic draw troubleshooting
Perfect for hunting automotive ignition off parasitic battery drains

Best For Automotive: Amprobe Low Amp Clamp Meter

Buy on Amazon

The amprobe low amp clamp meter's material feels more premium than its price would suggest. The Amprobe Lh41a digital clamp ammeter is an auto-ranging meter for measuring current in electrical testing applications. It has a transformer clamp that measures alternating current (ac) or direct current (dc) to 40 amp. It can display up to 3, 999 units (3-3/4 digits) before the operating range needs to be changed. It can set the hold function to keep the reading on the display, even after the meter is disconnected.

The Amprobe clamp is dramatically better, and actually lets you take measurements of low DC currents with confidence. It works well saving precious batteries. It is excellent for low currents, it will detect and resolve 10 microAmps and is very accurate for higher currents. The ranging meter automatically selects the correct operating range for the property being measured.
