Hioki LR8431-20 – 10 Channel Memory HiLogger
- USB flash drive support and improved accuracy
- 10 Channel
- 10 ms sampling and recording across all channels
- Noise-resistant measurement circuitry for improved readings
- Ultra-compact for convenient portability
Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, pulse or rotation signals, providing complete isolation between channels and strong noise resistance . The LR8431 logs data at 10ms speeds across 10 channels simultaneously, and features a bright color LCD for crystal clear waveform displays.
Real-time recording of up to 10ms/ sample data to USB or CF memory devices
Small and light enough for the palm of your hand – yet completely isolated
Logger Utility program supports multi-channel measurements via PC
The LR8431-20 delivers improved thermocouple measurement accuracy and reference junction compensation accuracy.
Example: When measuring 50°C water with a type-K thermocouple, The LR8431-20 provides improved accuracy of ±1.5°C, whereas previous models provided accuracy of ±3°C.
Ten Isolated Analog Input Channels
There’s no need to worry about differing potentials of measurement objects when measuring temperature and voltage. All ten analog channels are isolated. Even when measuring temperature and voltage at the same time, interchannel interference and electric shock hazards are eliminated. The four pulse channels are ideal for counting revolution pulses to measure rotation speed. (Pulse inputs share common ground.)
Note: Isolation between channels is possible through the use of semi-conductor relays. Voltage exceeding the product specifications, such as that originating from lightning surges or other sources, should never be applied between each channel; otherwise the relays will short and the recorder will be damaged.
High-Speed Sampling
10 ms Sampling and Recording Across All Channels
Abrupt changes in load need to be measured during development of EV • HV • PHV, for which multi-channel, 10 ms sampling is essential. This HiLOGGER can track waveforms that could not be followed with the 100 ms sampling interval previously available.
Enhanced Noise Suppression
Noise-resistant measurement circuitry for improved readings
Measurement involves the deployment of a delta-sigma type A/D converter. Suppress inverter switching noise and line-frequency hum by digital filtering with the HiLOGGER’s proprietary oversampling technology.
Note: Optimum noise suppression is obtained for recordings at least two seconds long
