Hioki LR8432 Heat Flow Data Logger – 10-Channel Logger for Thermal Analysis

Overview

The Hioki LR8432 is a precision heat flow data logger developed for engineers, researchers, and technical teams who need to evaluate thermal performance, insulation, and temperature-change causality. The device provides 10 isolated analog input channels, 4 pulse/rotation inputs, and supports direct input of heat flow sensors. With high-speed sampling (as fast as 10 ms), waveform-processing functions, and robust data storage via CompactFlash and USB media, the LR8432 offers both portability and comprehensive data-acquisition capabilities. Local power options include AC adapter, optional battery pack, or external DC supply for diverse deployment scenarios.

Key Features

• 10 isolated analog channels capable of ±10 mV to ±60 V (1-5 V range included), resolution down to ~500 nV

• Thermocouple measurement for types K, J, E, T, N, R, S, B from -200 °C to 1,800 °C (depending on sensor) with ~0.1 °C resolution

• Pulse / Rotation Inputs: 4 channels, counting pulses up to 1,000 M, rotation speed up to 5,000/n r/s

• High sampling speed: All channels can sample every 10 milliseconds

• Waveform processing / Numerical calculations: Simple average, moving average, integration, heat transmission coefficient, etc.

• Display: 4.3-inch WQVGA TFT color LCD (480×272) for waveform & gauge display. Dual-gauge display (heat flow + temperature) possible

• Data Storage: Internal memory + support for CompactFlash (CF) card & USB flash drive

• Power Options: AC adapter (100-240V), optional battery pack (model 9780) ~2.5 h continuous at 25 °C, external DC input 10-16V

• Size & Weight: Approx. 176 mm × 101 mm × 41 mm, weight ~550 g (without battery)

Applications

The LR8432 is suited for a variety of thermal measurement tasks including:

• Evaluating insulation performance of building materials & facades

【FAQ】

Q1: Does LR8432 directly display heat flow in W/m² or is scaling required?
A1: You can enter the sensitivity constant of your heat flow sensor directly, and the LR8432 will use that to scale sensor voltages into heat flow units (W/m²).

Q2: What is the fastest sampling interval across all channels?
A2: The LR8432 supports a minimum sampling interval of 10 ms for all analog input channels.

Q3: Are the analog input channels isolated? What about safety?
A3: Yes, the 10 analog inputs are isolated. Maximum allowable input is ±60 V DC; maximum rated voltage to earth ground is AC 30 Vrms / DC 60 V.

Q4: How is data stored and transferred?
A4: Data can be stored on an internal memory, or externally to Hioki CF cards or USB flash drives.

Q5: Can it be used in the field without AC power?
A5: Yes. You can use the optional Battery Pack model 9780 (≈2.5h at 25 °C) or external DC supply (10-16V) for field deployment.
