MEMORY HiLOGGER LR8431
Featuring USB Flash Drive and Improved Accuracy! Your Personal 10-channel Logger
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.
- Record measurement data on a USB flash drive for easy transfer to a computer
- Record to reliable Compact Flash cards during long-term measurement applications for increased peace of mind
- Replace storage media during real-time recording
- Improved thermocouple measurement accuracy and reference junction compensation accuracy
- Ten isolated analog input channels
- 10 ms sampling and recording across all channels
- Noise-resistant measurement circuitry for improved readings

|LR8431-20||10 ch, English model|
This compact logger excels in a broad range of settings, from production lines to research and development
For applications such as
- Evaluating motors and inverters used in electric and hybrid vehicles
The LR8431-20 enables stable, low-noise measurement of high-speed, high-resistance targets.
- Efficiency measurement and performance evaluation of air conditioning equipment
The LR8431-20 supports simultaneous, multi-point measurement, for example of input and output at multiple air conditioning registers or the temperature of internal components.
- Temperature measurement and performance evaluation of internal components in electronic equipment
Used with a wind velocity converter, the LR8431-20 can measure cooling efficiency inside equipment enclosures.
10-channel logger still fits in the palm of your hand
Ultra-compact for convenient portability.
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.)
*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.
A data logger with a 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 Memory HiLogger can track waveforms that could not be followed with the 100 ms sampling interval previously available.
Featuring USB flash drive and CF card support
The LR8431-20 can record measurement data on a USB flash drive for easy transfer to a computer.
In long-term measurement applications, it can also record to reliable Compact Flash cards for increased peace of mind.
Replace storage media during real-time recording.
Switch out fully loaded storage media with new ones while recording without stopping the measurement so that you can analyze any data recorded so far.
* During high-speed recording, be sure to insert the new storage media within 2 minutes of removing the former.
*Use only HIOKI CF cards, which are manufactured to strict industrial standards, for long-term storage of important data. Operation of non-HIOKI CF cards is not guaranteed.
