HIOKI LR8432-20 HEAT FLOW LOGGER
Compact & Lightweight Hioki LR8432-20 Heat Flow Logger for Analyzing the Causes of Temperature Change
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.
Key Features
• Use a heat flow sensor to measure the movement and volume of heat energy
• Measure of temperature and voltage
• 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
• Ten isolated analog input channels
• 10 ms sampling and recording across all channels
• Record raw waveforms and post-calculation waveforms at the same time. (Heat transmission coefficient processing)
• Two graduations can be displayed with a double gauge
Principal Applications * Automotive market (evaluating the flow of heat into the vehicle interior from the engine compartment, assessing heat damage to vehicle parts, identifying sources of heat, etc.) * Residential construction market (evaluating the insulation performance of building materials, evaluating the performance of radiant heating systems, etc.)
