HP-DH8 is a handheld, multi-sensor dynamic signal DAQ system designed for field tests and harsh interference environments, featuring 8-channel synchronous acquisition, 0.1 Hz–256 kHz sampling, and an integrated Windows 10 touchscreen for standalone measurement, analysis, and data storage.
| True mixed-input, multi-sensor acquisition | Each channel can be configured for different sensor/input types and used at the same time—ideal for multi-physics test setups. |
|---|---|
| Multi-excitation outputs | Supports multiple constant voltage/current excitation sources, including 0–10 V, +24 V, +12 V, and IEPE 24 V / 4 mA constant current. |
| Synchronous sampling, display & storage | All channels acquire, display, and save data synchronously; max sampling rate up to 256 kHz with software configuration. |
| Modular & lightweight design | Easy to carry; measurement points can be customized and combined flexibly for different test scenarios. |
| Flexible power options for field work | Supports AC 220V/50Hz or DC 12V; built-in 12V lithium battery enables 4 hours of independent operation—well-suited for outdoor impact/explosion tests. |
HP-DH8 is built for on-site dynamic measurements where portability and reliability matter. In complex electromagnetic interference conditions, it can simultaneously connect different sensor types per channel to capture multiple physical quantities such as shock, vibration, strain, voltage/current, displacement, temperature, and more—without relying on external conditioning modules.

Q1: What makes HP-DH8 “handheld” compared to rack DAQ systems?
HP-DH8 integrates Windows 10 + touchscreen + local storage + battery, so it can run tests without an external PC, ideal for field work.
Q2: Can I use IEPE/ICP accelerometers?
Yes. HP-DH8 provides built-in IEPE 4 mA constant current with conditioning.
Q3: Can different sensor types be used at the same time?
Yes. HP-DH8 supports mixed inputs across channels, so you can capture strain, voltage/current, displacement, temperature, acceleration, etc. in one synchronized test.
