Lascar EL-USB-2 Thermo-Hygrometer Logger with USB Interface for Storage and Facility Monitoring

USB Data Logger for Temperature and Humidity — Temperature and humidity monitoring with recorded data

This instrument fits facility teams, storage operators, laboratories, and compliance users that need a practical way to capture data during building a reliable record of environmental conditions for quality, traceability, and troubleshooting. 

This data logger has been widely cited in scientific and industrial studies for its reliable performance in monitoring environmental conditions. Industry reviews consistently highlight its accuracy, durability, and ease of use, while customer feedback frequently emphasizes its value for long-term monitoring of fridges, storage areas, and outdoor conditions. Common applications include pharmaceutical cold chain monitoring, agricultural climate tracking, HVAC system diagnostics, and food safety compliance.

The user can conveniently configure the logging rate and start time, and transfer the saved data by connecting the module directly to a PC's USB port and executing the specially designed software on Windows 2000, XP, Vista, and 7. Data on relative humidity, temperature, and dew point (the temperature at which water vapor in the air starts to condense) can subsequently be graphed, printed, and exported to different applications.

Long-Life Battery and Status Indication

The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for a year. Status indication is via flashing red and green LEDs. The logger is protected against ingress from water and dust to IP67 standard when the plastic cap and seal are fitted.

Features:

• Humidity/Temp USB data logger
• Configuration software
• User-selectable alarm thresholds
• LEDs indicate logger status
• IP67 protection
• Calibration certificate available

Applications:

The EL-USB-2 is suitable for a wide variety of applications, including:

• Pharmaceutical fridge monitoring
• Environmental and weather monitoring
• Agricultural and livestock
• Food & drink
• Building & site monitoring
• HVAC/R

To support comprehensive environmental monitoring workflows you may  integrate products such as the RTR‑503B All‑in‑One Wireless Temperature and Humidity Logger, which facilitates multi‑point condition tracking in temperature‑controlled storage and processing facilities with automatic data collection via compatible base units. For applications requiring enhanced precision and extended wireless range, the RTR‑507B Wireless Temperature and Humidity Logger with High Precision Sensor delivers refined measurement accuracy suited to sensitive goods and compliance documentation. Where multi‑parameter environmental data is critical, the RTR‑574‑S Wireless Temperature, Humidity, UV & Illuminance Logger expands monitoring capabilities to include light and UV metrics for sophisticated archives, exhibition, or climate‑sensitive inventory oversight.

Technical Q&A

How long does the battery typically last?

The EL-USB-2 comes with a long-life lithium battery that can typically log data for up to one year under normal conditions.

Is the logger waterproof?

Yes, with the plastic cap and seal fitted, the device is protected to IP67 standard against dust and water ingress.

Can I use it with modern Windows systems?

The supplied software is compatible with Windows 2000, XP, Vista, and 7. For newer Windows versions, compatibility may require running in compatibility mode or using alternative data analysis software.

What types of environments is this logger suitable for?

The EL-USB-2 is ideal for monitoring environmental conditions in pharmaceuticals, food storage, agricultural sites, HVAC systems, and general building monitoring.

Does it provide dew point measurements?

Yes, the device calculates dew point based on the recorded temperature and relative humidity readings, helping identify condensation risks.

When is data logging especially valuable?

Logging is valuable when trends matter more than a single spot reading, such as curing history, storage conditions, verification records, or alarm-driven incident response.

Who is this best suited for?

Facility teams, storage operators, laboratories, and compliance users will get the most value when they need repeatable measurements plus a record they can review, export, or act on later.

Because it combines Humidity/Temp USB data logger, Configuration software, User-selectable alarm thresholds, this product is a strong fit for temperature and humidity monitoring with recorded data where documentation and repeatability are important.
