OS1327D-Series

Supported Applications

The Omega OS1327D Series is a digital, non-contact infrared thermometer with Type K thermocouple input designed for remote temperature measurement. The device features a laser pointer for targeting and backlight illumination to facilitate use in dark environments.

Operating Conditions & Performance

The series measures temperatures from -50°C to 400°C (-58°F to 752°F) with an accuracy of ±1.5% of reading or ±1.5°C (±3°F), whichever is greater, and a resolution of 0.1°C / 0.1°F. The infrared sensor operates within a spectral response range of 8 to 14 μm with an adjustable emissivity setting from 0.10 to 1.00. Performance specifications include a distance-to-spot ratio of 12:1 and a response time of 1 second (95% response). The unit is rated for operation in ambient temperatures between 0°C to 50°C, relative humidity up to 80% max., and altitudes up to 2000 meters.

Key Performance Metrics

• Measurement Range: -50°C to 400°C / -58°F to 752°F
• Accuracy: ±1.5% of reading or ±1.5°C (±3°F), whichever is greater
• Spectral Response: 8 to 14 μm
• Emissivity Adjustment: 0.10 to 1.00 adjustable
• Laser Class: Class II, <1 mW, 650 nm

Configuration Options

The OS1327D Series integrates data logging capabilities and dual measurement modes. The internal memory stores up to 100 readings with a recall function for reviewing stored values. Users can switch units between °C / °F via the display interface.

Functional Features

• Data Logger: Stores up to 100 readings
• Display Options: LCD with backlight illumination
• Input/Output: Type K thermocouple input and output signal capability
• Laser Targeting: Class II laser pointer for aiming
• Power Management: Auto power off after 10 minutes of inactivity; powered by 2 x 1.5V AAA batteries (approx. 5000 readings battery life)
• Holding Function: Auto hold reading feature activates upon trigger release

Safety and Environmental Constraints

The device includes specific operational warnings: avoid direct laser radiation to eyes, prevent reflected laser from reaching eyes on smooth surfaces, do not radiate the laser toward inflammable gas, and do not operate near large electrical or magnetic fields. Users should keep the unit away from direct sunlight, hot objects (>70°C/158°F), high humidity, and dust. Condensation may form on the focal lens when moving from cold to hot environments; wait for it to dissipate before measuring.

Key Product Differences

The OS1327D Series is identified by the model number guide format: OS1327D - <MODEL> - <TYPE> - <FEATURES>. The series includes an enclosed CD containing software and protocol documentation. Physical dimensions are 180 x 80 x 40 mm with a weight of approximately 250 g.

Manufacturing origin is Taiwan, and the product carries CE marking along with ISO 9001 Certification (Stamford, CT and Manchester, UK). A one-year warranty applies to this series. Note: These products are not designed for use in human applications.
