OM-EL-USB-1-Series

Supported Applications

The Omega OM-EL-USB-1 Series consists of portable temperature data loggers designed to measure and store up to 16,382 temperature readings. The series is configured for use with Windows 98, 2000, or XP operating systems via a purpose-designed software application that allows users to set logging rates, start times, graph results, print reports, and export data.

Documented applications include general temperature monitoring where the unit can be plugged directly into a PC's USB port for setup and data download. The series is not designed for use in human applications.

Operating Conditions & Performance

The OM-EL-USB-1 model operates within a measurement range of -25 to +80°C (-13 to 176°F). Overall accuracy (error) is specified as ±1 (±2) °C (°F), with an internal resolution of 0.5 (1) °C (°F).

Logging rates are configurable from every 10 seconds up to every 12 hours. The unit is powered by a 1/2AA 3.6V Lithium Battery, which provides at least one year of life when operating at a logging rate of once per minute and an ambient temperature of 25°C.

Physical dimensions for the OM-EL-USB-1 are 98.0 mm (3.86 in) x 26.0 mm (1.02 in). The data logger is protected against moisture to IP 67 standard when the protective cap is fitted. Correct functioning of the unit is indicated by flashing red, green, and orange LEDs.

Key Performance Specifications

• Measurement Range: -25 (-13) to +80 (176) °C (°F)
• Accuracy (Overall Error): ±1 (±2) °C (°F)
• Internal Resolution: 0.5 (1) °C (°F)
• Logging Rate Range: Every 10s to every 12hr
• Battery Life: Minimum 1 year @ 25°C and 1m logging rate
• Enclosure Rating: IP 67 (with protective cap fitted)

Configuration Options

The series includes multiple model variants identified by the following stock numbers: OM-EL-USB-1, OM-EL-USB-2, OM-EL-USB-2-PLUS, OM-EL-USB-3, and OM-EL-USB-4. While detailed specifications for all models are not provided in this bundle, the series supports USB interface connectivity for setup and data download.

Standard configurations include a long-life lithium battery supplied with the unit. Replacement batteries are available under model number OM-EL-BATT; these must be used as they are 'press fit' without solder tags. The stored readings do not lose their data when the battery is flat or replaced, though logging stops until the battery is reinstalled and data downloaded.

Available Options

• Replacement Battery: OM-EL-BATT (Omega model only)
• Software Interface: Purpose-designed software for Windows 98, 2000, or XP included on CD with the standard data logger.

Key Product Differences

The bundle identifies five distinct variants within the OM-EL-USB-1-Series family: OM-EL-USB-1, OM-EL-USB-2, OM-EL-USB-2-PLUS, OM-EL-USB-3, and OM-EL-USB-4. The provided documentation details specifications specifically for the OM-EL-USB-1 model.

Specific technical differences between these variants—such as measurement ranges, accuracy classes, or memory capacities—are not detailed in the available source documents beyond their distinct part numbers. Users should consult specific datasheets for models other than OM-EL-USB-1 to confirm variant-specific capabilities.
