Fluke 324 True-RMS Clamp Meter

The Fluke 324 is a versatile clamp suitable for many commercial and residential troubleshooting applications. The Fluke 324 forms part of the affordable Fluke 320 range of clamp meters. The 320 range includes a great range of benefits such as a 2 year warranty, wide 30mm jaw and display hold as standard. Every unit in the range, the 323, 324 and 325 are designed to verify the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts.

Measure temperature and capacitance

Stepping up from the Fluke 323, the Fluke 324 adds both temperature (-10.0°C to 400.0°C) and capacitance (100.0μF to 1000μF) measurement, further adding the the units versatility. The Fluke 324 still retains its ergonomic form and is ideal for those who require a reliable and advanced clamp meter but without paying extra for DC current measurement. HVAC engineers will benefit from the addition of temperature measurement on the 324.
