Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, resistance, humidity and pulse signals, providing complete isolation between channels and strong noise resistance. The LR8400 Series logs data at 10ms speeds across 30 channels simultaneously, is expandible up to 60 channels, and features a bright color LCD for crystal clear waveform displays. Key Features |

How to Analyze the Temperature Efficiency of a Refrigerator using the Hioki LR8400 Series Memory HiLogger Use the Hioki LR8400 Memory HiLogger series to analyze the temperature difference between the external body and internal cavity of a refrigerator. Cold chain temperature management is particularly important for maintaining the integrity of storage systems for vaccines, perishables, and other temperature-sensitive products. The temperature of the refrigeration equipment at various internal and external points must be constantly monitored for sudden thermal excursions. Notwithstanding the multi-channel capabilities of the LR8400, the time scale axis of the data logger can be freely adjusted to display measured waveforms first as a trend in terms of seconds, then in terms of minutes, while still recording. Observe temperature changes from the very beginning and fast-forward to the present right on the screen. |

A multichannel data logger that’s ideal for battery, automotive, and environmental measurement For applications such as |
 |
Portable data logger with 30 standard channels expandible to 60 channels Heat flow and temperature gauges can be displayed simultaneously for data measured with the Heat Flow Logger LR8432-20. The instrument comes with 30 channels as standard, but another two 15 channel input units can be added to expand the total number of channels to 60. The instrument also features 8 channels of pulse and digital input. Note: The units provided with the unit as standard cannot be removed. |
 |
A data logger with a sampling speed of up to 10 ms The development of hybrid and electric automobiles requires instruments that can measure abrupt load changes. The instrument can reliably capture even abrupt changes in load since it can measure channels 1 to 15 in 10 ms. Note: Measurements on channels 31 to 60 provide 50-ms sampling. |
 |
A high-withstand-voltage data logger with a maximum rated channel-to-channel and channel-to-ground voltage of 300 V The HiLOGGER measures not only fuel cells, but also batteries for UPS (uninterruptible power supplies) devices used in buildings as well as batteries consisting of cells and packaging connected in stacks that require multi-point measurements. In such measurements, high voltage for the whole stack is applied between channel-to-channel and channel-to-ground. The universal unit delivers safe measurement thanks to a high-withstand-voltage design featuring a maximum rated channel-to-channel voltage of 300 V DC. Note: Isolation between channels is possible through the use of semi-conductor relays. |
