• Product Description

    The new CM100 True RMS current meter is fitted with a highly flexible current sensor 8.5mm in diameter, ideal for measurements on difficult sizes and shapes of conductors in hard to reach areas where conventional clamps won’t go.

    The TRMS capability ensures accurate and reliable AC current measurement for distorted waveforms caused by today's power electronics and non-linear loads.

    Measurements are accurate and reliable with 3 ranges up to 3000A AC and resolution of 10mA in the 30A range. The light weight flexible sensor head will accommodate conductors up to 160mm in diameter and can be threaded through small apertures. Unlike conventional current transformers there is no maximum overload limitation.

    The separate display module is fitted with a 1.8m lead giving even more freedom when working in areas with restricted access and is backlit for viewing in low light conditions. The Hold function can be used for saving displayed values and for longer term monitoring, the auto power off function can be easily disabled and Min/Max values recorded.

    The CATIV 600V safety rating make the flex meter ideal for utility and industrial current measurement applications.

    The CM100 is supplied with alkaline batteries and manual. All Martindale clamp meters come with a 2 year warranty.
