Clamp Meter
Extech Instruments MA200
Overview
The compact Extech MA200 is a useful general purpose AC clamp meter for plant maintenance technicians, electrical troubleshooters, and DIYers. The 4-digit (2,000-count) readout is easy to read and you can operate the meter with one hand, having a thumb-dial selector that is ergonomically placed off the side of the meter. You can select auto- or manual-ranging and measurement functions in addition to current include: voltage and resistance as well as diode and continuity tests.

- 400A AC Current
- 2000 count LCD display
- Max Hold
- Overload protection for all ranges
- 0.9″ (23mm) jaw size accommodates conductors up to 300MCM
The clamp meter is compact and easy to hold. Whether you are performing amp readings in a heavy duty industrial setting or doing commercial electrical work, the 400 amp AC rating and ample 0.9-inch (23mm) jaw opening is compact enough to fit in tight locations but can also accommodate bigger jobs, swallowing conductors up to 300 MCM. For better diagnostics and troubleshooting, you can use one of two one-button functions: press HOLD to freeze a reading on the LCD; MAX tracks and displays maximum values (useful for blind measurements and start-up draw).
