The DwyerOmega OM-90 Series is a compact, portable USB data logger designed for reliable monitoring of temperature and humidity in transport, storage, and environment-sensitive applications. With small form factor and battery power, it offers the ability to log conditions in-transit or onsite without bulky instrumentation or constant supervision.
Built to be simple yet precise, the OM-90 devices measure temperature from -30 °C to +80 °C (-22 °F to 176 °F) and relative humidity from 0-100 % RH, with higher accuracy in most critical ranges. When paired with the free USB-based software, users can configure logging intervals, download data directly, and quickly export files for reporting and trend analysis.
This logger series includes high/low alarm indicators (via LEDs) to alert immediately when readings stray outside acceptable thresholds—a must for applications like vaccine transport, perishable food shipments, museum or archival item storage, and anywhere strict environmental control is needed.
Key strengths of the OM-90 include long battery life (up to 4 years in typical conditions), a clear interface, versatility in starting modes (delay, immediate, push-button), and very user-friendly software that requires no special drivers. Whether you’re monitoring cold chain compliance, conducting field studies, or managing asset condition in remote locations, the OM-90 Series delivers dependable data tracking with minimal fuss.
