World’s Premier Digital Multimeter. Superior Accuracy and High Response, Topped with Safety Terminal Shutters
The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters. The DT4281 is our top-of-the-line high-precision 60000 count digital multimeter with all of the functions and features required for advanced testing in complex power and electrical applications. CAT IV 600 V, CAT III 1000 V Key Features • 60000 count, 5-digit display, high-resolution measurements • ±0.025% DC V basic accuracy, wide 20 Hz to 100 kHz AC V frequency characteristics • Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms) • Includes multiple measurement functions such as DC+ACV, temperature, capacitance, and frequency • Terminal shutter mechanism (prevents erroneous test lead insertion) • Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention) • Measure up to 10A with direct input (DT4282 only) • Dual display lets you check voltage and frequency simultaneously • Magnetic strap (Optional) • Rear kickstand • Store probes at the back of the tester • Identify excessively high input with a red screen backlight • Robust design capable of withstanding a drop from a height of 1 m • USB communications function supports PC measurements (optional) • Broad -15 (5°F) to 55°C (131°F) operating temperature range
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)Regarding DMM Accuracy Due to the many ranges and functions available in a DMM, only the basic accuracy is indicated for reference. Please refer to the individual catalogs for detailed accuracy information. * Zero-suppression: For small inputs below the guarantee range, zero is effectively displayed.
