Hioki LR8432
The Hioki LR8432 is a compact and lightweight 10-channel heat flow logger designed for evaluating insulation performance and analyzing the causes of temperature changes. By measuring heat flows and temperatures simultaneously, the LR8432 provides valuable insights into thermal energy movements and quantities, enabling users to identify the root causes of temperature fluctuations.
Key Features
- 10 isolated analog input channels for measuring heat flow, temperature (thermocouples), voltage, and pulse
- 10 ms sampling and recording across all channels
- Record raw waveforms and post-calculation waveforms simultaneously, including heat transmission coefficient processing
- Display heat flow and temperature gauges side-by-side for easy comparison
- Specialized functions for heat flow measurement:
- Easy scaling settings: directly enter the sensitivity of the heat flow sensor
- Calculations: waveform processing function for analyzing temperature and heat flow (simple average, moving average, integration, heat transmission coefficient), integration with numerical calculations
- Record measurement data on a USB flash drive or reliable Compact Flash cards for easy transfer to a computer
Principal Applications
- Automotive market: Evaluate the flow of heat into the vehicle interior from the engine compartment, assess heat damage to vehicle parts, identify sources of heat
- Residential construction market: Evaluate the insulation performance of building materials, assess the performance of radiant heating systems
- Identify whether automotive parts are releasing or absorbing heat to implement optimal thermal countermeasures
- Compare the performance of insulating materials in an effective manner
By visualizing heat flows and quantities of heat, the Hioki LR8432 Heat Flow Logger is a valuable tool for professionals in various industries, including automotive, construction, and product development, who need to understand and optimize thermal performance.
