Jual Memory Hilogger Hioki LR8431-20
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.
Key Features
- 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
- Ultra-compact for convenient portability
- Widescreen, bright LCD gives excellent viewability
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.
