Hioki DT4255 DIGITAL MULTIMETER
The Hioki DT4255 Digital Multimeter is the ideal tool for professionals working in harsh work environments. With fuse-protected terminals and a CAT IV 600 V, CAT III 1000 V rating, this digital multimeter ensures maximum safety while conducting electrical testing.
The DT4255 also features a voltage detection function and accepts an AC clamp sensor, making it an all-in-one tool for voltage and current measurement. It even has a low-pass filter function, allowing for accurate measurement of output voltage on the secondary sides of inverters by eliminating harmonic components.
To prevent short-circuit accidents, the resistance measurement function features a protective circuit that prevents erroneous operation, and the tester circuitry quickly and reliably disconnects with a fast-blow fuse. The DT4255 also eliminates the root cause of accidents by providing clamp-on sensor-based current measurement functionality instead of using conventional probes.
Data can easily be downloaded, reviewed, and saved to a computer with the optional Communication Package DT4900-01. The computer and multimeter are electrically isolated by means of optical communications, ensuring data can be sent without concern for electrical hazards.
The Hioki DT4255 Digital Multimeter is designed and manufactured in Japan to ensure the highest possible quality, and it comes with a 3-year warranty for peace of mind. It is important to use an instrument that suits the measurement location, and the DT4255 satisfies the required safety level for electrical testing. Choose the Hioki DT4255 Digital Multimeter for fast, safe, and accurate electrical testing.
