HEAT FLOW LOGGER

LR8432

Compact & Lightweight 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.)

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.


A heat flow logger that’s ideal for addressing the root cause of changes in temperature

The LR8432-20 is a heat flow logger that visualizes quantities of heat. By using a heat flow sensor to visualize movements of thermal energy (heat flows) and quantities of thermal energy, you can obtain data that serves as a leading indicator of changes in temperature.


Heat flow loggers as a useful tool for formulating thermal measures in R&D and performance evaluation

Visualizing heat flows (inflows and outflows) and quantities of heat with a heat flow logger is useful when you need to implement more precise air-conditioning control or formulate thermal measures as part of the product development process. ●Isolation of heat generated and dissipated in automotive parts ●Evaluate the thermal performance of building materials ●Measure the energy efficiency of consumer electronics ●Study the impact of body heat ●Diagnose the deterioration of insulation material in plant piping ●Index temperature fluctuation in agriculture and civil engineering


Display heat flow and temperature gauges simultaneously

Heat flow and temperature gauges can be displayed simultaneously for data measured with the Heat Flow Logger LR8432-20. Display the gauges for data you want to compare at the same time in order to see changes in temperature and heat flow at a single glance.


Waterproof heat flow sensor that can measure curved surfaces

This heat flow sensor can measure curved surfaces such as those found on water pipes. Choose from three available sizes to measure objects that were impossible to isolate for measurement before, for example the surfaces of small parts and narrow gaps. Sensor’s Operating temperature range:-40℃〜150℃ (-40°F to 302°F)
