Current & Voltage Clamp Meter Suppliers

The ultimate benefit of a current clamp meter is its potential to save lives. The whole point of this essential device is to separate an electrician from live electricity while measuring current flow.

Current clamp meters measure AC current, though some also measure DC current. Both versions do so without any direct contact with the conductor while taking current flow measurements on a handheld meter.

The clamp part of a current meter is clamped to the conductor. The electrician or technician then connects to the clamp on the handheld meter and takes measurements safely without having to make contact with live wires while doing so.

While the primary function of a current clamp meter is to measure AC and DC current, many can also measure:

• frequency
• capacitance
• phase
• resistance
• temperature

Unlike basic current testers that can throw a wobbly measuring a mere 10 amperes, current clamp meters can measure up to 1000 amperes. That’s why current clamp meters are the preferred option for electrical maintenance, servicing and installation.

• Does it enhance safety? High quality current clamp meters will, but cheaper options may not. Make sure the unit you choose has an excellent safety rating.
• Is the screen size optimal?
• Is it smartphone compatible?
• Does it measure both AC and DC or just AC?
• Does the clamp reach into tight spaces?
• Is the clamp size right? Clamps generally range between 17mm and 45mm. If you’re only working with smaller conductors, choose a smaller clamp. If it varies, choose something larger to cover all likely scenarios.
• Is it accurate?
• Is it durable?
• Will it be used outdoors?

The cheapest current clamp meters are only about $50, but the average price for a reliable unit is a little over $414. Of course, as this is an important device and safety is vital, it’s worth the extra investment to get a high-end current clamp meter. One of those will cost about $1,900.

• Speed and efficiency issues caused by loop instrumentation
• False readings caused by clamping around more than one conductor
• An excessive rush of current due to an excess of starting torque

• Store at room temperature away from strong magnetic fields
• Avoid placing in areas with vibrations as this can loosen meter components
• Clean with a lightly damp cloth and dry thoroughly
