Lascar EL-USB-2-LCD+ USB Temperature and Humidity Data Logger with LCD Display (-35 to 80 °C / 0–100% RH)

Standalone USB Temperature and Humidity Data Logger with 16,000+ Reading Capacity

This standalone temperature and humidity monitor is designed for accurate environmental monitoring and secure data logging in demanding applications.

It measures and stores over 16,000 combined temperature and humidity readings across a wide range of -35 to +80°C (-31 to +176°F) and 0 to 100% RH, with a resolution of 0.5°C (1°F) and 0.5% RH. Ideal for laboratories, warehouses, HVAC validation, food storage, pharmaceuticals, and transport monitoring, this compact USB data logger ensures reliable performance and traceable records.

Continuous monitoring allows facilities to document environmental conditions over time and verify that storage or processing environments remain within acceptable limits. For example, pharmaceutical storage guidelines emphasize the importance of continuous temperature monitoring and recordkeeping to ensure drug stability and regulatory compliance (NCBI: Cold Chain and Temperature Monitoring in Pharmaceutical Supply Chains). Similarly, environmental monitoring of temperature and relative humidity is recommended in museums and archives to prevent material degradation and preserve collections.

Accurate Environmental Monitoring

The wide measurement range makes this logger suitable for both cold-chain and high-temperature environments. With 0.5°C and 0.5% RH resolution, users can monitor subtle environmental changes that may impact product quality, compliance, or research results.

Large Memory and Flexible Logging Intervals

With storage for more than 16,000 readings, this device supports long-term monitoring without frequent downloads. Adjustable logging intervals from 10 seconds to 12 hours allow you to configure the unit for short-term validation studies or extended environmental tracking.

Simple USB Setup and Data Export

The logger connects directly to a computer via USB and works with free EasyLog software for configuration, data download, graphing, and export. This makes it easy to generate reports for audits, quality control documentation, and regulatory compliance.

Visual Alerts and Alarm Thresholds

User-programmable high and low alarm limits for both temperature and humidity help ensure environmental conditions remain within specified tolerances. Red and green LED indicators provide clear visual status updates at a glance.

Durable IP67-Rated Housing

Built with IP67 environmental protection, this monitor is resistant to dust and water ingress, making it suitable for industrial settings, storage facilities, and transportation environments where durability is essential.

For a scalable environmental monitoring solution

this temperature and humidity monitor with data logging can be complemented with additional specialized instruments designed for broader facility oversight. For example, the RTR-507B wireless temperature and humidity logger with high precision sensor is well suited for controlled environments where strict measurement accuracy is required, such as laboratories, environmental chambers, or sensitive storage areas. In distributed monitoring networks across warehouses or production spaces, the RTR-503B all-in-one wireless temperature and humidity logger provides reliable wireless data collection and centralized data management capabilities. For facilities that also require indoor air quality verification, the RTR-576 wireless temperature, humidity and CO2 logger adds CO₂ monitoring to temperature and humidity tracking, supporting comprehensive environmental assessment across commercial and industrial sites. Together, these instruments allow organizations to build an integrated monitoring system tailored to demanding operational and compliance requirements.

Q&A

How many readings can this temperature and humidity data logger store?

The device can store over 16,000 readings covering both temperature and relative humidity measurements, making it suitable for long-term monitoring applications.

Can I set custom alarm limits for temperature and humidity?

Yes, users can program high and low alarm thresholds for both parameters. LED indicators clearly show when readings move outside the configured limits.
