Precision Measurement in Tight Spaces: MESTEK CM85C True-RMS AC/DC Mini Digital Clamp Meter in Malaysia

In modern electrical diagnostics, automotive troubleshooting, and industrial control cabinet maintenance across Malaysia, technicians frequently face overcrowded wire looms and tight spatial constraints where standard clamp meters cannot fit. MTM Precision is proud to introduce the MESTEK CM85C True-RMS AC/DC Mini Digital Clamp Meter—an ultra-compact, high-precision instrument specifically engineered for seamless current and voltage testing in restricted working areas.

Certified to EN61010-2-032 standards with a CAT III 600V safety rating, the MESTEK CM85C combines high portability (weighing just 150g) with flagship features including AC/DC True-RMS current measurement, a 22mm narrow jaw opening, Zero Clearing function for precise DC measurements, and K-type thermocouple temperature auditing.

🌟 Key Features & Compact Engineering Capabilities

Miniaturized Form Factor for Tight Spaces: Slim body design measuring only 165 mm x 55 mm x 19 mm, allowing technicians to easily slide the clamp jaw into densely packed distribution boxes, terminal blocks, and automotive engine bays.
22mm Narrow Clamp Jaw Opening: Specially shaped 22mm jaw opening facilitates clean isolation of single wires in crowded cable bundles without disturbing adjacent wiring.
AC/DC Current Measurement with Zero Clearing Function: Measures both AC and DC current (2A / 20A / 100A) with high sensitivity. Includes a one-touch ZERO Clearing button to eliminate residual magnetic field interference prior to DC current measurements.
True-RMS Processing: Ensures accurate readings when testing distorted non-linear AC waveforms generated by variable frequency drives, switching power supplies, and electronic ballasts.
K-Type Thermocouple Temperature Testing: Integrated temperature measurement capability supporting -20°C to 1000°C (-4°F to 1832°F) for rapid inspection of HVAC coils, electrical contact points, and bearing housings.
Non-Contact AC Voltage Detection (NCV): Non-contact sensor detects live AC voltage presence through insulated cables and conduit walls safely.
Backlit LCD Screen & Data Hold: High-clarity backlit display for dark working spaces, with Data Hold functionality to lock measurements on screen.
