Professional 600A Current Measurement: MESTEK CM83A+ / CM83B / CM83C Digital Clamp Meter Series in Malaysia
For industrial electricians, HVAC system engineers, motor maintenance technicians, and power quality auditors across Malaysia, reliable non-invasive current measuring tools are critical for daily operations. MTM Precision is proud to present the MESTEK CM83A+, CM83B, and CM83C 600A Digital Clamp Meter Series—a high-performance lineup of professional clamp-on meters built for precise electrical diagnostics and HVAC testing.
Certified to EN61010-2-032 safety compliance and rated at CAT III 600V, the MESTEK CM83 series combines a 32mm jaw capacity, high-resolution digital displays (up to 10,000 counts), True-RMS signal processing, and motor Inrush current measurement capabilities in a portable, ergonomic housing.
🌟 Key Features & Advanced Capabilities
-
600A AC Non-Invasive Clamp Measurement: Accurately measure AC currents up to 600A without breaking the circuit, utilizing a large 32mm jaw opening suitable for standard conductors and thick industrial cabling.
-
Inrush Current Measurement for Motor Startup (CM83C): Captures transient startup currents when electric motors, compressors, or heavy inductive loads power on, assisting in troubleshooting breaker trips and electrical sizing issues.
-
True-RMS Signal Processing (CM83B & CM83C): Delivers precise AC voltage and AC current measurements on non-linear or distorted waveforms commonly found in variable frequency drives (VFDs) and electronic power supplies.
-
10000 Counts High-Resolution Display (CM83B & CM83C): Provides enhanced display resolution (up to 10000 counts) for finer precision when testing low-magnitude signals or sensitive circuits.
-
Non-Contact AC Voltage Detection (NCV): Safely detect live AC voltage presence through wire shielding and conduit boxes without direct metallic probe contact.
-
Integrated Flashlight & LCD Backlight: Features a bright LED work light pointing at the clamp jaw alongside a backlit screen for safe work in dark breaker panels and ceiling spaces.
-
Wide Range Temperature Measurement (CM83C): Supports thermocouple temperature testing from -20°C to 1000°C (-4°F to 1832°F), essential for HVAC technicians auditing heat exchangers and electrical connections.
