WIRELESS UNIVERSAL UNIT LR8511

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 Hioki LR8511 is a wireless, 15-channel universal input module for measuring voltage, temperature, humidity or resistance, utilizing Bluetooth® wireless technology to send measured data to the Hioki LR8410 Wireless Logging Station.

Key Features

Input module to capture logging data using Bluetooth® wireless technology. Install in hard-to-reach locations (*1)
Choose an input module based on the parameters you wish to measure (15-channel type)
Easily add up to 7 input modules wirelessly to keep your environment free of tangled wires (*2)
100 msec simultaneous sampling across all channels using rapid scanning method

*1:Over line-of-sight distances of up to 30 meters. The presence of obstructions may shorten this range.
*2:For a total of up to 7 modules for the LR8410 main unit, max. 105 channels when using 15-channel modules.

LR8511	For the LR8410

The LR8511 alone is not capable of making measurements. Wireless logging station Model LR8410-20 is necessary to measure. The main unit and input modules are not bundled with the Battery Pack Z1007. Thermocouples are not provided by HIOKI, and must be purchased from a separate vendor.
Models LR8512 to LR8515 may only be used in countries in which they have been certified.
These products emit radio waves. Use of radio waves is subject to licensing requirements in certain countries. Use in countries or regions other than those listed above may constitute a violation of law, exposing the operator to legal penalties.
For the latest information about countries and regions where wireless operation is currently supported, please see the specifications.

Make measurements of interior conditions from the outside, with the door closed

● Have you dealt with problems like these?
We can’t close the windows or doors due to all the wires. As a result, there’s a gap in the gasket, and the vehicle cannot be sealed.

● Resolved with wireless data transmission
Wires do not protrude outside the vehicle, allowing the windows and doors to be closed so that the vehicle can be tested under airtight conditions.
