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 Hioki LR8432 is a handheld 10-channel data logger especially designed for heat flow measurement. The Heat Flow Logger is ideal for evaluating insulation performance and analyzing the causes of temperature change.

Notes
The LR8432-20 is not bundled with the Battery Pack 9780. Thermocouples are not provided by Hioki, and must be purchased from a separate vendor.Use only Hioki CF cards, which are manufactured to strict industrial standards, for long-term storage of important data. Correct operation of non-Hioki CF cards or USB memory sticks is not guaranteed.
