MEMORY HiLOGGER LR8450
1 ms Sampling Portable Logger Expandable to 120 Channels with Your Choice of Plug-in Modules
Hioki Memory HiLoggers are high-speed data loggers for recording multiple channels of voltage, temperature, resistance or humidity signals, some models providing complete isolation between channels and strong noise resistance.
The LR8450 offers a sampling speed of up to 1 ms and up to 120 channels, depending on the types of plug-in modules that are selected. The modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.
Actual measurement example using CAN UNIT
This video shows how the MEMORY HiLOGGER LR8450-01 and CAN UNIT are used to measure the temperature of an actual vehicle. The analog data measuring the temperature inside the vehicle and the CAN data are simultaneously displayed on the waveform in real time. You can also see how the measured analog data is output as CAN signals in real time.
Stable Logging - Even at High Voltages and Frequencies. Minimize the Effects of Noise.
The LR8450 reduces the effects of noise to deliver stable logging, even at high voltages and frequencies.
Legacy data loggers could not log temperature accurately in noisy environments due to the effects of high frequencies, which caused values to shift or fluctuate significantly.
Hioki Memory HiLogger LR8450 uses a revamped design to dramatically reduce the effects of high-frequency noise, and is ideal for temperature logging of inverters and batteries.
Key Features
- Expandable to 120 ch with wired/plug-in modules
- Record voltage output from pressure and other sensors with 1ms sampling speed
- Directly connect strain gauge and measure signals in as fast as 1ms intervals
- Significantly reduced effects from noise let you safely measure in high voltage and high frequency areas such as around inverter motors

Scope 3 emission reduction through recording of current consumption and heat energy loss
To attain Scope 3 (*1) emissions targets and ensure alignment with decarbonization goals, it is important to accurately understand the impact of our products on the environment.
We will offer tips to aid developers striving for Scope 3 compliance, focusing on techniques to pinpoint energy losses in electronic components through current and temperature data acquisition.
Measurement of Leakage Current in EV Power Management
In the domain of e-mobility, especially electric vehicles (EV), range extension is one of the most important priorities. To boost range, it’s important to measure power consumption and leakage current not only for batteries and powertrains, which use a large amount of power, but also for devices such as ECUs and electrical accessories.
Connect strain gages directly and make measurements in as little as 1 ms.
The Memory HiLogger LR8450 is a data logger that can measure stress via directly connected strain gages. Capable of recording at frequencies on the order of dozens of hertz thanks to sampling at up to 1 ms, the LR8450 is ideal for measuring stress and load on moving parts and strain on components such as brakes and pipes. And because it can accommodate a mix of various measurement units, the LR8450 can simultaneously measure strain, temperature, and voltage as necessary.
Gain up to 120 channels of input simply by adding a total of four plug-in modules
Analog 600 CH Synchronous Sampling Measurement [Since V2.10]
Synchronized sampling up to 5 plug-in modules (600 analog channels) can be measured when multiple LR8450's external sync terminals (SYNC.IN, SYNC.OUT) are connected.
Note: This function cannot be used when wireless modules are connected.
Sample output from a variety of sensors, including 1 ms pressure sensors
Use model High Speed Voltage Unit U8553
Measures at a sampling rate of up to 1 ms.
1 ms sampling rate is the best match to measure sensor outputs with a frequency response of under 100 Hz, for example pressure and vibration sensors.
Measure strain with a 1 ms sampling rate
Example: strain measurement
Use model Strain Unit U8554
Connect strain gauges directly and measure at a sampling rate of up to 1 ms.
Strain gauges tend to have long, thin wires that are easily broken, but that potential pitfall can be avoided by using wireless modules so that wire length is minimized.
Measure temperature near an inverter or battery
Example: temperature measurement
Use models:
Voltage/Temp Unit U8550
Universal Unit U8551
Measures at a sampling rate of up to 10 ms.
Battery EV thermal management by measuring temperature and heat flow
Heat flow can be measured by combining the LR8450 with the FHF05 Heat Flux Sensor. Since these sensors allow both temperature and the direction of heat movement to be confirmed, they are useful when validating thermal management.
