HIOKI DT-4221 Digital Multimeter

HIOKI DIGITAL MULTIMETER DT4221

Pocket-sized DMM for Electricians, Featuring ±0.5% Accuracy
The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The DT4221 is a pocket-sized digital multimeter designed specifically for electrical work requiring optimal safety, with ±0.5% DC V accuracy and wide 40Hz to 1kHz AC V bandwidth.

Overview

• Achieving a high level of safety in a compact body and lightweight design
• Test leads conveniently wrap around the back
• ±0.5% DC V basic accuracy, wide 40 Hz to 1 kHz AC V frequency characteristics
• Low-pass filter (100 Hz/ 500 Hz) cuts high harmonics
• Current measurement function eliminated to enhance safety
• Broad -10 (14°F) to 50°C (122°F) operating temperature range
