Built Tough, Tested Safe Your safety is non-negotiable. The FS899L is engineered with dual safety ratings (CAT.III 1000V / CAT.IV 600V) to handle high-energy circuits without compromising protection. Double fuses and overload safeguards prevent burns and shocks, while CE and RoHS certifications back its reliabilitywhether you're under the hood or in the panel.
True RMS Precision You Can Trust Get lab-accurate readings every time. With 6000 counts and True RMS technology, this meter delivers precise measurements across the board: AC/DC Voltage (60mV-600V, ±1.2-1.5%), Current (300mA-10A, ±2.2-2.5%), Capacitance (10nF-60mF), Resistance (600-60M), plus frequency and ambient temperatureeverything a pro needs to diagnose with confidence.
One Tool, Endless Diagnostics From household outlets to industrial machinery, the FS899L handles it all. Measure AC/DC current & voltage, continuity, resistance, capacitance, frequency, and even detect live wires without contact (NCV). Plus, ambient temperat
