The Hioki DT4281 Digital Multimeter gives you high accuracy and fast response time and improves efficiency with useful functions suitable for professional testing such as new energy development and facility maintenance.
In maintenance inspections of electrical equipment in buildings and manufacturing plants, and research and development as well as maintenance inspections of equipment such as inverters and solar power systems, the ability to make high-precision measurements without compromising work efficiency is essential. The HIOKI Digital Multimeters DT4281 and DT4282 were developed to help professionals do their jobs quickly by enabling efficient, high-precision measurement.
Both instruments feature reduced measurement times, allowing them to deliver the fastest response speed of any portable multimeter. As reflected by safety performance that allows use in applications up to CAT IV (600V), the most demanding measurement category, and a broad operating temperature range, they are also inherently safe products that can be used with confidence and peace of mind. Furthermore, with basic accuracy of ±0.025% for DC voltage measurement and an AC voltage frequency band of 20 to 100 kHz, the new DMMs deliver the highest accuracy and broadest frequency band of any portable multimeter.
