HP-JC is a 10 Hz synchronized, multi-channel static DAQ for reliable measurement of strain, voltage, current (0–20 mA / 4–20 mA), temperature (RTD/thermocouple), resistance, and displacement in lab and field monitoring.
| Multi-purpose universal input | Supports multiple connection types. Can simultaneously connect strain, current, voltage, temperature, resistance, displacement and other sensors. No extra auxiliary equipment needed—true universal input. |
|---|---|
| High accuracy | Each channel includes an independent high-precision 120 Ω bridge resistor, stable signal conditioning/amplifier circuit, and high-performance ADC. Accuracy up to 0.2% with fast sampling; all channels are synchronized at 10 Hz. |
| Battery-powered option | Optional built-in lithium battery to avoid AC 220V power limitations on site. |
| Portable & modular | Modular, lightweight design for easy carrying and multi-unit networking. Customizable measurement points to build multi-channel acquisition systems. |

Q1: Is 10 Hz enough for strain testing?
For static testing and slow-changing signals, 10 Hz synchronized sampling is commonly used to ensure stable, low-noise data and consistent comparison across channels.
Q2: Can I mix strain + temperature + displacement in one test?
Yes. HP-JC supports mixed sensor inputs, making it suitable for multi-parameter monitoring.
Q3: Does it support 4–20 mA sensors?
Yes, it supports 0–20 mA and 4–20 mA acquisition, plus voltage and resistance transmitter outputs.
