Display of remaining time on recording media for superior convenience

Model LR8431-20 Memory HiLogger constitutes an update to the HiLogger 8430-20. The new instrument introduces two major improvements to its predecessor: USB flash drive support and improved thermocouple measurement accuracy.

Thanks to its ability to write data recorded over an extended period of time to a USB flash drive, the Hioki LR8431-20 Memory HiLogger makes it much easier to save measurement data. The instrument can also write to conventional CF cards, allowing operators to select the media that best suits their application.

The LR8431-20 displays how much time is remaining based on available space on CF card and USB flash drive recording media, allowing operators to avoid running out of space while recording. The LR843120 uses a high-brightness QVGA TFT wide LCD, ensuring waveforms are easy to see

The LR843120 fits in the palm of your hand, making it the smallest instrument in its class. Just 101 (H) by 176 (W) by 41 (D) millimeters in size and weighing just 550 grams (without peripherals), the instrument offers excellent portability and mobility. It can measure 10 channels at sampling speeds as high as 10 milliseconds.
