1000A AC/DC Clamp Meter (True RMS)

SKU: ACM-3345


This professional true RMS clamp meter provides AC current and AC/DC voltage readings regardless of waveforms. They are ideal for industrial and commercial applications where non-linear loads distort the current or voltage waveform. Combining high reliability and durability, overload protection is provided for all ranges. The clamp meter has an impact-resistant ABS plastic housing with soft touch non-slip rubber and mid-size teardrop-shaped jaws which give easy access into confined trunking.

Calibration Options

A calibration service can be purchased for this unit. Once the Service has been performed a certificate of calibration is produced and dispatched with your order. Calibration Services are performed on receipt of your order and as such will delay shipping. Details and options are outlined below.

Traceable Calibration (Clamp Meter) Price
Issued at 5 points: Volt d.c, Volt a.c,  Amps d.c,  Amp a.c, Ohms
Traceable certification is adequate for most applications and meets the calibration requirements of ISO 9001. All measurements contained in this type of certification are traceable back to National UKAS Standards.
UKAS Calibration (Clamp Meter) Price


A UKAS calibration can also be considered traceable. The difference between the two is that UKAS calibrations are carried out under the remit of an ISO/IEC 17025 quality system by a laboratory that has been accredited by UKAS, to ensure the consistency and accuracy of results.
