Hioki LR8431-20 Memory HiLogger, 10 channels

Description

The Hioki LR8431-20 Memory HiLogger is a compact, 10-channel data logger designed for high-speed, multi-point measurement of voltage, temperature, pulse, or rotation signals. It features 10 isolated analog channels, providing high noise resistance and safety when measuring objects with differing potentials. The logger is highly portable and includes a bright, color LCD for real-time waveform display.

Key Features

• Measurement channels: 10 analog input channels, which are electrically isolated from each other and from the chassis ground. It also has 4 pulse-counting input channels.
• Sampling and recording speed: Records data at a high speed of 10 ms (100 Hz) across all 10 channels simultaneously.
• Noise resistance: The measurement circuitry is designed to resist noise, including inverter switching noise and line-frequency hum, by using a delta-sigma A/D converter and proprietary oversampling technology.
• Measurement types (pulse channels): Supports count integration and revolution measurement using no-voltage contact, open collector, or voltage input.
• Input terminals: M3 screw terminal blocks are used for analog input connections.
• Display: A 4.3-inch color TFT-LCD allows for easy-to-view waveform displays and simultaneous numerical and alarm status readouts.
• Data storage: Supports storage to external media like a USB flash drive or a Compact Flash (CF) card. Recording can continue uninterrupted while storage media is being replaced.
• PC interface: Connection to a PC is via a USB cable, and the bundled Logger Utility software enables real-time data acquisition and analysis.
• Multi-unit connection: Up to five LR8431-20 units can be connected to a single PC via USB for multi-channel measurements of up to 50 analog channels.
• Alarm output: Features one non-isolated alarm output channel.
• Power source: Operates on AC power (100 to 240 V) via the included adapter and can be used with an optional NiMH battery pack for portable applications.
• Dimensions: 176 mm (W) x 101 mm (H) x 41 mm (D).
• Weight: Approximately 550 g.
