Hioki LR8514 Wireless Humidity Logger for Flexible Temperature and Humidity Monitoring
In production plants, storage areas, agricultural sites, and equipment enclosures, environmental conditions can have a direct impact on product quality, equipment reliability, and process stability. The Hioki LR8514 Wireless Humidity Logger is designed to help users record and manage temperature and humidity data more easily by combining compact size, wireless data collection, and flexible installation options. Hioki positions the LR8514 as a 2-channel wireless humidity logger that is ideal for recording temperature and humidity in places where larger instruments may be difficult to install.
One of the LR8514’s biggest advantages is its compact, field-friendly design. Hioki highlights that the logger is a compact two-channel model that can fit where other devices do not, making it useful for installations inside control panels, around equipment, or in other tight spaces. The product page also notes that the optional magnetic strap can help users mount the unit on walls or other surfaces, giving it more flexibility in difficult installation environments.
The LR8514 is also built for convenient wireless data collection. Hioki states that the logger includes Bluetooth wireless technology, allowing users to download measurement data to a tablet, smartphone, or computer without needing to remove the logger from the test location. Hioki also explains that data collected during measurement is automatically merged into a single file, helping users review waveforms and numerical values in the field more efficiently.
From a measurement standpoint, the LR8514 supports 2 channels for temperature and 2 channels for humidity, with two sensors attachable to the unit. Hioki specifies a measurable temperature range of -40 °C to 80 °C and a humidity range of 0 to 100% RH, with maximum resolution of 0.1 °C and 0.1% RH. Using the supported Z2010 or Z2011 sensors, Hioki lists basic accuracy of ±0.5 °C for temperature and ±3% RH for humidity under specified conditions.
Another practical strength is recording capacity and power flexibility. Hioki says the LR8514 can store 500,000 data points per channel and can be powered by an AC adapter, two AA alkaline batteries, or an external 5 to 13.5 V supply. The product page notes operating time of about 20 days on AA batteries at a 1-second recording interval with Bluetooth on, and up to 3.5 months at a 1-minute interval with Bluetooth off.
The LR8514 can also be used with the Hioki LR8410-20 for real-time waveform viewing and logging-module operation, giving users additional flexibility when integrating it into broader data acquisition workflows. For teams that need a practical way to monitor environmental conditions in production, storage, and agricultural settings, the Hioki LR8514 offers a strong combination of compact installation, wireless convenience, and reliable data recording.
