MS2001 & M266 Series AC Digital Clamp Meters
MS2001 & M266 series AC digital clamp meters deliver multi-function testing (V/A/R/F/T), high accuracy (±1%–±4% Rdg+Dgt), 2000/20000-count displays, data hold, backlight, diode/continuity tests. Compact (218–235mm), lightweight (272–330g), 9V battery-powered, with 42–50mm jaw diameters—ideal for electricians, technicians, and DIYers in electrical diagnostics.
Product Overview
The MS2001 & M266 Series AC Digital Clamp Meters are professional tools designed for precise electrical measurement across diverse applications. The MS2001 series (including MS2101 for AC/DC) focuses on AC systems, while the M266 series enhances versatility with broader DC voltage support. Both series integrate core functions: measuring AC/DC voltage (up to 1000V), AC current (20A–1000A), resistance (200Ω–40kΩ), frequency (0–10MHz), and temperature (-30℃–1000℃).
Key features include high-resolution displays (2000/20000 counts for clear readings), data hold for stable measurements, backlit LCD for low-light use, and built-in tests (diode check, continuity, transistor hFE). The MS2001 series adds 3-terminal transistor testing, while M266 emphasizes compact portability.
With 9V battery power, lightweight designs (272–330g), and compact dimensions (218×90×44mm to 235×95×44mm), these meters are field-ready. Jaw diameters (42–50mm) accommodate thick wires, and packaging (10–20 units/carton) suits bulk deployment. Ideal for circuit troubleshooting, appliance maintenance, and industrial inspections, they combine accuracy, durability, and user-friendly operation for professionals and DIY enthusiasts alike.
