Description
LR8432 Heat Flow Logger for Thermal Analysis
The Hioki LR8432 Heat Flow Logger is purpose-built for professionals who need a deeper understanding of how heat moves through materials, systems, and environments. Unlike traditional temperature-only loggers, this heat flow logger visualizes both the movement and quantity of thermal energy, helping users identify leading indicators of temperature change rather than reacting after fluctuations occur.
With ten isolated analog input channels, the LR8432 Heat Flow Logger delivers stable and accurate measurements even in electrically noisy environments. It supports heat flow sensors, temperature sensors, and voltage inputs, making it a versatile solution for multi-parameter thermal analysis.
Insulation and Performance Evaluation
By measuring heat inflow and outflow directly, the LR8432 Heat Flow Logger allows engineers and researchers to evaluate insulation performance with confidence. In residential construction, it helps assess building materials and radiant heating systems. In automotive applications, it supports analysis of heat transfer from engine compartments into vehicle interiors and helps identify heat damage risks in components.
The logger also plays a critical role in research and development. Visualizing heat flow enables precise formulation of thermal countermeasures, improved air conditioning control strategies, and better energy efficiency design for consumer electronics and industrial equipment.
Advanced Data Recording
The LR8432 Heat Flow Logger records data at a fast 10 ms sampling rate across all channels, ensuring accurate capture of dynamic thermal events. It can record raw waveforms alongside post-calculated waveforms, including heat transmission coefficient processing, allowing users to analyze both measured and derived data without additional post-processing steps.
For long-term measurements, data can be saved directly to CompactFlash cards, while USB flash drive support allows quick data transfer to a computer. Hioki recommends using approved storage media to ensure reliable operation during extended logging sessions.
Intuitive Display
The LR8432 Heat Flow Logger features a dual gauge display that allows heat flow and temperature data to be viewed simultaneously. This side-by-side visualization makes it easy to identify correlations and trends at a glance, improving analysis efficiency during on-site measurements and evaluations.
Its compact and lightweight handheld design makes it suitable for field use across automotive testing sites, construction locations, agricultural environments, and laboratory settings.
