Catalogs

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 LR8515 Wireless Voltage/Temperature Logger provides
easy, wireless collection of a variety of data types, including voltage
input and thermocouple types K and T, all in a single device.

Data can be downloaded using Hioki’s tablet and smartphone app (for Android devices).

Model No. (Order Code)

LR8515	2 ch, sensor is sold separately

Note: The LR8514 alone is not capable of making measurements.
Only the temperature and humidity sensors affect the
measurement accuracy and are subject to calibration.
The LR8514 logger does not require calibration.

	A compact, 2-channel wireless temperature logger with voltage input as well as K and T thermocouple capability For applications such as ● Checking the correlation of voltage and temperature ● Maintenance of PV systems (while connected to an actinometer) ● Various tests for electronics/automobiles/transportation ● Easily checking heat flows (while connected to a heat flow sensor)
	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. *Pictured: LR8514
	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. *Pictured: LR8514
	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 7 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.
