Compact and Lightweight Heat Flow Logger for Energy Conservation Analysis
Hioki Memory HiLoggers are high-speed data loggers for recording multiple channels 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.
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.)
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)
