Hioki DT4255 Digital Multimeter, 40 Hz to 1 kHz VAC

Description

The Hioki DT4255 is a True RMS digital multimeter designed for professionals who need high safety, accuracy, and reliability in industrial and field environments. It is part of the DT4200 series of digital multimeters.

Key Features

• True RMS measurement: Provides accurate measurements of even distorted AC waveforms by calculating the true Root Mean Square value.
• Enhanced safety: The multimeter has fuse-protected voltage measurement terminals to prevent short-circuit accidents. It also uses a current-limiting resistor and a fast-blow fuse for overcurrent protection.
• High-category safety ratings: The DT4255 is rated for CAT IV 600V and CAT III 1000V, making it suitable for electrical testing in high-energy environments.
• Broad operating temperature: It can function in a wide temperature range of -25°C to 65°C (-13°F to 149°F), making it durable for various field locations.
• Low-pass filter: The filter cuts out high-frequency harmonic components, allowing for more accurate readings of fundamental inverter waveforms.
• Current measurement: The DT4255 measures AC current using a clamp-on sensor, which eliminates the risk of a short-circuit from mistakenly measuring voltage with the current range probes.
• Dual display: It allows for the simultaneous viewing of voltage and frequency.
• PC communication: An optional USB communication feature allows for data logging and downloading measurements to a computer.
• Durable design: The meter is constructed to be shockproof and resistant to dust, with an O-ring seal protecting the rotary switch.
