MEMORY HiLOGGER LR8450-01 (Wireless LAN model)

1ms Sampling Portable Logger Expandable to 330 Channels with Your Choice of Plug-in or Wireless Input 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 LR8450-01 offers 1ms sampling across up to 330 channels, and can be paired with 10 different types of plug-in or wireless input units. Collect data from wireless modules installed in remote or confined locations via a LAN connection. New input modules measure strain and distortion, ideal for automotive applications involving the evaluation of vehicle components as well as robotic equipment.

Key Features

• Wireless LAN model expandable to 330 ch with wireless and 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
• Avoid wiring issues by minimizing cable length using wireless units
• Monitor data captured remotely on PC with wireless LAN technology

Note: The LR8450 and LR8450-01 cannot perform measurement on their own. One or more plug-in modules or wireless modules are required (sold separately).
Note) The LR8450-01 and wireless modules emit radio waves. Use of radio waves is subject to licensing requirements in certain countries. Using it in a country or region other than those indicated may violate the law and may result in legal penalties for the operator.

Wireless units can be easily registered in 2 steps!

Memory HiLogger LR8450-01 is a data logger equipped with wireless LAN. It is ideal for collecting data in dispersed locations and locations where wiring is difficult. You can add up to 7 wireless units and measure up to 330 channels. Will introduce to you two easy steps, to register the wireless units onto the main module.

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.

Add a total of up to 7 wireless units for a maximum of 330 channels

With four U8552 VOLTAGE/TEMP Units and seven LR8532 WIRELESS VOLTAGE/TEMP Units, you can measure a total of 330 channels.

Sample output from a variety of sensors, including 1 ms pressure sensors

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

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

Measures at a sampling rate of up to 10 ms.

Make measurements in locations where it would be difficult to route wires

Work time can be reduced by using the LR8450-01 and wireless units, since only minimal wiring is required. If the measurement target is located in a lab, this approach eliminates the need to string wire and drill holes in the walls of the monitoring room where data is checked.

Observe data from a remote location using a PC or tablet

By connecting the LR8450-01 to a PC or tablet via a wireless LAN, you can control the instrument remotely using the built-in HTTP server or download data files using the built-in FTP server.
