Measure Load Current and Leak Current Easily with Clamp Sensors
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 LR8513 is a wireless, 2-channel
AC/DC current input module that utilizes Bluetooth® technology to either
send measured data to the Hioki LR8410 Wireless Logging Station or to an
Android (TM) tablet.

Model No. (Order Code)

LR85132 ch, sensor is sold separately

Key Features

• Measure AC and DC load current and AC leak current
• Choose from many current sensors
• Place inside a distribution panel, close the cover, and monitor measured values from the outside
• Measure power easily—just set the voltage and power factor
• Compact, two-channel model fits where other devices don’t
• Download measurement data to a tablet or computer with Bluetooth® wireless technology or capture in real time with the LR8410
• Three-way power (AC adapter, AA alkaline batteries, or external 5 to 13.5 V power supply)
• Store 500,000 data points per channel

Note: The LR8513 alone is not capable of making measurements.

Precautions concerning use of the CT7731, CT7736, and CT7742 to measure AC/DC load current

The AC/DC Auto-zero Current Sensor CT7731/CT7736/CT7742 cannot be connected directly to the Wireless Clamp Logger LR8513.

The Display Unit CM7290 and Output Cord L9095 is required to connect those sensors to the LR8513.

Precautions concerning use of the CT7044, CT7045, and CT7046 to measure AC/DC load current

The AC Flexible Current Sensor CT7044/CT7045/CT7046 cannot be connected directly to the Wireless Clamp Logger LR8513.

The Display Unit CM7290 and Output Cord L9095 is required to connect those sensors to the LR8513.

A compact 2-channel clamp logger that’s ideal for simple measurements such as AC/DC load current or AC leakage current

For applications such as
● Assessing demand every 30 minutes (average value recording)
● Assessing peak leakage current (Maximum value recording)
● PV maintenance
● Automobile tests
● Forklifts
● Railroads
● Equipment maintenance
● Simple electrical measurement (set the voltage and power factor)


A wireless logger whose data can be captured by a smartphone or PC

Built-in Bluetooth(R) wireless technology.

Use your tablet or PC to collect data even as signals are being logged.

No matter what time during measurement you collect the data, data is automatically merged together into one single file.
Review data trends by observing waveforms and numerical values right there in the field.

Real-time monitoring

By using the Hioki LR8410-20 to acquire data, you can view the waveforms in real time.

Furthermore, previous waveforms can be viewed while the device is taking measurements.

A compact wireless logger that you can place anywhere

Pocket size for installation anywhere.
Use the optional MAGNETIC STRAP to hang it on a wall – solving all of your installation space problems.

Installing a data logger in a switchboard or control panel has never been easier.
Gone is the need to feed wiring through the panel-data collection is done wirelessly so you can close the panel door for safe measurements.

The loggers are also useful for measuring in difficult-to-wire locations, like high places or on moving machines.


Power with AA batteries or an AC adapter

The logger will operate for about 10 days on two AA-size alkaline batteries.
(Recording interval: 1 sec, with Bluetooth(R) ON)

Since the batteries will last longer the less time the Bluetooth(R) function is operating, the instrument features a power-saving function that automatically turns on the Bluetooth(R) circuit during predefined time periods.

While communications are disabled, data is reliably stored in the instrument’s large built-in memory, which can hold 500,000 data points per channel.

Use the AC adapter to record data over extended periods of time with peace of mind.
