MA140

The MA140 from Extech Instruments is a compact true RMS 300A AC clamp meter with built-in non contact voltage (NCV) detector. The non contact voltage NCV detector allows for quick detection of live voltage. This clamp meter takes true RMS measurements for accurate readings of noisy, distorted or non sinusoidal waveforms. The MA140 can measure up to 300A AC. Compact 0.8" (22mm) jaw size accommodates conductors up to 300MCM and allows measurements in tight locations.

• Inrush current measurement
• 6000 count backlit LCD display
• Smart data hold, audiovisual alert when a new reading exceeds 50 digits of a held reading
• Low battery indicator and auto power off feature
• 80V to 600V non contact voltage (NCV)
• 60A, 300A AC current (0.01A max resolution) and basic accuracy of ±2%
