Description
LR8515 Voltage/Temperature Logger for Wireless Data Collection
The Hioki LR8515 Voltage/Temperature Logger is designed for professionals who need accurate and flexible data logging without the hassle of cables. Its wireless Bluetooth® capability allows measurement data to be collected directly on a tablet or PC in real-time, making field work faster and safer. Data collected is automatically merged into a single file, ensuring seamless trend analysis and reporting.
Compact Design and Flexible Applications
This 2-channel logger is compact enough to fit in tight spaces, switchboards, or control panels, yet powerful enough to monitor a wide range of signals. Users can measure everything from small voltage outputs of pyranometers and heat flow sensors to battery voltage and thermocouple-based temperature readings. Optional magnetic straps make wall or equipment mounting easy, allowing installations in difficult-to-wire locations like high places or moving machinery.
Reliable Data Storage and Power Options
The LR8515 stores up to 500,000 data points per channel, ensuring long-term measurement reliability. It can operate on two AA batteries for about 7 days at a 1-second recording interval with Bluetooth® enabled, or it can run from an AC adapter or an external 5–13.5 V power supply for extended monitoring. A built-in power-saving function ensures the Bluetooth® circuit is active only during predefined periods, extending battery life without losing any recorded data.
Real-Time Monitoring and Data Review
With the LR8515, you can view live waveforms on a tablet or PC during measurements. Previous waveform data remains accessible even as new signals are logged. This feature makes it ideal for applications such as PV system maintenance, electronics or automotive testing, and checking heat flow with compatible sensors.
