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.
Model No. (Order Code)
Note: The LR8431 is not bundled with the Battery Pack 9780. Thermocouples are not provided by HIOKI, and must be purchased from a separate vendor.
This compact logger excels in a broad range of settings, from production lines to research and development
For applications such as
● Efficiency measurement and performance evaluation of air conditioning equipment
● Temperature measurement and performance evaluation of internal components in electronic equipment
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.
*Isolation between channels is possible through the use of semi-conductor relays.
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.
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.
Replace storage media during real-time recording.
* During high-speed recording, be sure to insert the new storage media within 2 minutes of removing the former.
Included PC application with measurement and analysis functionality
The supplied Logger Utility software enables processing of measurement data on a PC.
Use the supplied Logger Utility software to record data on a PC in real-time.
Connect the PC to the HiLOGGER using USB.
*USB connection photographs depict the LR8400.
