Extech EX520A True RMS priemyselný multimeter CAT IV 600V, 40.000 Counts, IP67

The Extech EX520A is a rugged true RMS multimeter built for demanding electrical troubleshooting in harsh environments. Its IP67 waterproof and dustproof housing withstands temporary immersion, making it suitable for outdoor and industrial use where dust and moisture are present. The 40,000-count display offers high resolution for precise readings, while the CAT IV 600V safety rating allows safe measurements on the supply side of the main breaker.

Highlights

• True RMS sensing for accurate AC measurements on non-sinusoidal waveforms
• 40,000-count backlit LCD with analog bargraph
• CAT IV 600V and CAT III 1000V safety ratings
• IP67 waterproof and dustproof design
• Measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, and temperature
• Min/Max/Average and Peak Hold functions
• Diode and continuity tests with audible beeper
• Powered by a single 9V battery

In daily use

The EX520A is comfortable to hold and operate with one hand, thanks to its rugged over-molded housing and large rotary selector. The bright backlight and clear display make readings easy in dimly lit areas. Auto-ranging speeds up measurements, while the data hold function freezes the reading for later review. The Type K thermocouple input (thermocouple not included) extends the meter's capabilities to temperature measurement from -50°C to 1000°C.
