Hioki - Heat Flow Logger LR8432-20
Model No :
Hioki - LR8432-20
Part Code :
LR8432-20

Overview

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.

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

Major 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
