Description
LR8514 Wireless Humidity Logger for Accurate Environmental Monitoring
The Hioki LR8514 Wireless Humidity Logger is engineered for professionals who need reliable, long-term monitoring of temperature and humidity without installation complexity. Designed for production plants, agricultural sites, storage facilities, and construction environments, this logger delivers precise environmental data where it matters most.
Equipped with a high-precision ±3% RH humidity sensor, the LR8514 allows users to accurately track changes in ambient conditions and compare temperature and humidity levels across two separate locations. This makes it especially valuable for identifying environmental variations inside and outside equipment, storage areas, or production zones.
Wireless Humidity Data Logger with Bluetooth Connectivity
The LR8514 Wireless Humidity Logger features built-in Bluetooth technology, allowing users to collect measurement data directly on a smartphone, tablet, or computer while logging is in progress. Data collected at different times is automatically merged into a single file, eliminating manual data consolidation and reducing the risk of data loss.
On-site trend analysis is simple, with waveform and numerical data available instantly for quick decision-making. When paired with compatible Hioki instruments, real-time waveform monitoring further enhances visibility into environmental changes.
Compact Humidity Logger Designed for Flexible Installation
With its pocket-sized form factor, the LR8514 Wireless Humidity Logger fits easily into control panels, switchboards, and other confined spaces. Optional magnetic mounting accessories allow the device to be securely attached to walls or metal surfaces, making installation fast and non-invasive.
Wireless operation removes the need for routing cables through panels, allowing doors to remain closed for safer measurements. This makes the logger especially useful in hard-to-wire locations such as elevated areas or moving machinery.
Long-Term Temperature and Humidity Logging
Powered by two AA alkaline batteries, the LR8514 can operate for up to 20 days at a one-second recording interval with Bluetooth enabled. A built-in power-saving function extends battery life by activating Bluetooth only during scheduled periods. For extended monitoring applications, an AC adapter or external power supply can be used with confidence.
All recorded data is securely stored in the device’s large internal memory, ensuring uninterrupted logging even when wireless communication is disabled.
