1ms Sampling Portable Logger Expandable to 120 Channels with Your Choice of Plug-in Input Modules

SKU: LR8450 Category:


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 1 ms sampling across up to 120 channels, and can be paired with 5 different types of plug-in input units. New input modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.

Key Features

  • Expandable to 120 ch with wired/plug-in units
  • 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

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. The new 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.

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 units

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 units 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.
