2026 Upgraded FS899L Digital Multimeter Tester with Color Display, USB C Rechargeable Electric Test, Automatic Digital Display, 6000 Beads True RMS AC/DC Tester

Built Tough, Tested Safe Your safety is non-negotiable. The FS899L is designed with dual safety rating (CAT.III 1000V / CAT.IV 600V) to handle high-energy circuits without compromising protection. Dual fuses and overload safeguards prevent burns and bumps, while CE and RoHS certifications support its reliability, whether under the hood or on the panel.
True RMS Accuracy You Can TrustGet accurate lab readings every time. With 6000 beads and True RMS technology, this meter delivers accurate 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 room temperature. All a whole pro pro pro needs to diagnose with confidence.
One tool, endless diagnostics From home shots to industrial machinery, the FS899L handles it all. It measures AC/DC current and voltage, continuity, resistance, capacitance, frequency and even detects non-contact live wires (NCV). Plus, room temperature readings make it an ideal choice for HVAC and appliance troubleshooting built-in versatility.
WORK IN THE DARK, SEE EVERYTHING Narrow panels and dim basements? No problem. The massive 4.8-inch backlit display delivers crisp readings in low light, while the built-in flashlight illuminates your workspace.
