GMC I PRO SyS Ltd design and manufacture a range of high performance AC and AC/DC current probes and clamp meters for use with multimeteres, oscilloscopes and other recording instruments. Using Rogowski and advanced Hall­Effect technologies with a patended magnetic circuit we provide a range of customised and standard distribution products. All probes give an analogue output directly proportional to the measurement current, which is compatible with a wide range of measuring instruments.
