EXSYS EX-3606 USB Temperature and Humidity Data Logger with Alarm, Black

Laboratory managers and HVAC technicians often need to track environmental conditions over time without constant manual checks. The EXSYS EX-3606 USB data logger records temperature and relative humidity at user-defined intervals, storing up to 32,000 readings for later analysis via USB. Its programmable high/low alarms trigger an LED alert when conditions drift outside safe ranges, making it a practical tool for monitoring storage rooms, server cabinets, or climate-sensitive equipment.

Key specifications

• Measures temperature from 0°C to 55°C (32°F to 131°F) with ±0.5°C accuracy (0-40°C)
• Measures relative humidity from 5% to 95% RH (non-condensing) with ±3.0% RH accuracy (20-80% RH)
• Stores 32,000 data points: 16,000 temperature and 16,000 humidity readings
• Logging interval selectable from 2 seconds to 24 hours
• USB 2.0 interface for quick data download to PC
• Programmable high/low alarm limits for both temperature and humidity
• Status and alarm LEDs for at-a-glance monitoring
• Powered by a 3.6V lithium battery (1/2 AA) with approximately 1 year battery life
• Operating temperature: 0°C to 55°C; storage temperature: -40°C to 70°C
• Compact black housing, 9.5 mm slim profile

Why choose it

This logger combines precision and ease of use. The included Windows software (XP through 11) lets you configure logging intervals, set alarm thresholds, and export data for reports. The long battery life and large memory mean you can deploy it for months without intervention. Its slim design fits into tight spaces, and the LED alarms provide immediate visual warning without needing to connect to a computer.

Ideal use cases

• Monitoring temperature and humidity in pharmaceutical storage or cold chains
• Tracking environmental conditions in server rooms and data centers
• Recording climate in museums, archives, or greenhouses
• Verifying HVAC system performance over time
• Ensuring compliance in food storage and transport

Good to know

The EX-3606 is a standalone logger; you set it up via USB, then disconnect and place it in the target environment. Data retrieval is straightforward: plug it back into a PC and use the software to download and graph readings. The battery is user-replaceable, extending the device's service life. Note that the humidity sensor should not be exposed to condensing environments for prolonged periods.
