The EXTECH EX530 Industrial MultiMeter – 11 Function, Heavy Duty &True RMS
Designed to withstand harsh environments and usage, the meter’s rugged, double-molded housing is IP67-rated (waterproof and dustproof) and drop-tested to 6 feet. The large, illuminated LCD displays a 5-digit readout to 40,000 counts, and a useful 40-segment bar graph for analog comparisons and quick “needle-swing” tests. The EX530 capture various key readings, including capacitance, frequency (dual sensitivity for electrical and electronic applications), diode and continuity functions. The meter features a high 0.06 percent accuracy and a CAT IV 600-volt safety rating, protecting users even on outdoor wiring. Backed by a three-year limited warranty, the EX530 is also available with NIST calibration.
True RMS Compensates for Distortion from Electronic Devices
The Extech 530 is a True RMS DMM. It can be very difficult to make accurate current and voltage readings in industrial and commercial applications when electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic systems can distort the AC waveform, making it hard for averaging meters to get an accurate read. True RMS uses a more advanced formula to adjust for this kind of distortion. Powered by a 9-volt battery, the EX530 has Auto Power Off (with disable) to conserve battery life.
As a waterproof tool, the EX530 is popular among marine technicians and boat mechanics who risk dropping the meter off a boat, pier or dock, into water. Since the meter is waterproof and floats, it’s easy to recover and is ready to resume working once retrieved.
Users also enjoy convenient, one-button access to frequently used functions: Min/Max, Average, Hold, Relative Hold, Peak Hold, as well as selectable auto-ranging or manual-ranging. To avoid fussing with selecting the right measurement range when working on a variety of components from small electronics to main electrical sources, the meter automatically adjusts with auto-ranging. Besides electrical and electronic diagnostics, you can also take temperature measurements using the Type K bead wire probe included.
