Hioki Honored at JECA Fair 2019 Product Competition

Hioki is pleased to announce that the AC/DC Clamp Meter CM4376 received an honorable mention at the JECA (Japan Electrical Construction Association) Fair 2019.

June 20, 2019 - Nagano, Japan
Regular maintenance and management are essential in order to keep electrical equipment operating properly in buildings and manufacturing plants.  Clamp meters make it easy to measure current simply by clamping the jaws of the instrument around the cable being measured, and as a result they have entered into wide use in maintenance management applications. Distribution panels have been shrinking in recent years, with the result that the wires inside them are packed closer together. Less space between adjacent cables makes it harder for technicians to do their jobs.
The CM4376 AC/DC Clamp Meter, which is designed to be more easily clamped around wires, has the thinnest sensor in the industry at 9.5 mm, allowing it to be applied to wires that are surrounded by just 13 mm of space. This capability makes it possible to measure currents at a point directly underneath circuit breakers—a task that was impossible with its predecessor—and significantly boosts work efficiency when making such measurements. Additionally, the sensor can be paired with GENNECT Cross, a free smartphone app whose waveform display and logging functionality boost convenience by allowing users to visualize current.

At the fair’s product competition, the CM4376 was praised by measurement professionals for delivering improved performance, work safety, and peace of mind.

Hioki will take encouragement from this accolade as it continues to provide unique products from the customer’s perspective.
