Analog Clamp Ammeter BLOW 51-075 — measurement up to 7.5 A, analog display, clamp-style current meter

Analog clamp ammeter BLOW 51-075 is a compact clamp-style current meter with an analog display designed for measurement up to 7.5 A. Its hinged clamp jaw allows non-contact measurement of conductor current without interrupting the circuit, making it suitable for quick checks and basic electrical troubleshooting. The analog needle display provides continuous, easy-to-read indication of current values and reacts in real time to changes in the measured circuit.

Advantages

The clamp jaw design permits safe and quick current measurement on single conductors without disconnection, while the analog display offers immediate visual feedback and simple interpretation. Small size and lightweight construction make the instrument convenient for fieldwork and workshop diagnostics. The meter requires no complex setup and is suitable for users who need a straightforward tool for routine checks and basic maintenance tasks.

Suitable for

• Routine current checks on household and light commercial circuits
• Basic electrical troubleshooting and diagnostics
• Field service and workshop inspection where portability is needed
• Educational demonstrations of current flow and measurement principles

Key specifications

• Measurement range: up to 7.5 A (AC/DC depending on instrument design)
• Display type: analog needle (scale markings for current)
• Clamp jaw: hinged design for non-contact conductor measurement
• Form factor: compact, handheld housing suitable for field use
• Power: battery powered (replaceable) for portable operation

How to use

Open the clamp jaw and place it around a single conductor to be measured, ensuring the conductor is centered in the clamp for the most accurate reading. Read the value indicated by the needle on the analog scale while observing any marked range limits. Avoid clamping around multiple conductors simultaneously, as this will produce incorrect readings. Power the meter according to the manufacturer's instructions and replace batteries as needed to maintain reliable operation.

Usage recommendations

For safe and accurate results, use the clamp ammeter on one conductor at a time, verify the correct measurement range, and observe standard electrical safety procedures such as insulated gloves and keeping clear of exposed live parts. Store the instrument in a dry environment and check the analog scale and clamp mechanism periodically for damage or wear.
