Digital Lux Meter Split Design Bluetooth 99-Set Storage – UNI-T UT381A

High-Resolution Luminous Intensity Auditing

The UNI-T UT381A represents the pinnacle of portable light measurement technology, designed to meet the rigorous demands of modern lighting professionals. In the South African industrial and commercial landscape—where adherence to occupational health and safety (OHS) lighting standards is critical for productivity and safety—the UT381A provides the unalterable data needed to optimize work environments. Its sophisticated optical sensors and digital processing allow for precise measurements of everything from dim emergency exits to high-intensity sunlight and specialized industrial lighting.

Professional Split-Type Sensor and High-Capacity Range

The UT381A excels by providing a versatile and high-performance measurement platform:

• Detachable Split-Type Sensor: The remote sensor allows for flexible positioning, ensuring the operator can capture light intensity at the precise point of interest without their own body shadowing the measurement. This is essential for auditing workstation surfaces and localized machinery lighting.

• Massive 400,000 Lux Range: Capable of measuring extreme light levels, making it suitable for outdoor solar intensity studies as well as high-output industrial floodlighting.

• Precision Optical Module: Utilizing a high-stability silicon photocell with an integrated color correction filter, the UT381A delivers laboratory-standard accuracy across various light sources, including LED, fluorescent, and incandescent.

Wireless Intelligence and Advanced Data Management

The UT381A is built for the modern digital workflow, prioritizing data integrity and ease of use:

• Bluetooth 5.0 & iENV App Sync: Wirelessly transmit live measurements to a smartphone for remote monitoring. The dedicated app allows for the generation of charts and reports, facilitating seamless documentation for energy audits and compliance verification.

• 20,000-Set Internal Memory: Log extensive data during long-duration lighting stability tests. The meter can record data autonomously, providing a detailed history of light level fluctuations over time.

• MAX/MIN/AVG Statistical Tracking: Instantly identify lighting extremes and calculate average illuminance levels across a space, critical for verifying uniformity in lighting design.

Rugged Industrial Build and User Efficiency

Designed for the rigors of field service, the UT381A features a durable, ergonomic housing that is optimized for long-term reliability. The large, high-contrast backlit LCD ensures error-free data reading in dark storage vaults or brightly lit outdoor environments. The intuitive interface allows for rapid toggling between Lux and Foot-candles (FC), ensuring compatibility with diverse international standards and client reporting requirements.

Key Features & Technical Advantages:

• 400,000 Lux / 40,000 FC Range: High-capacity measurement for any lighting scenario.

• Bluetooth 5.0 Connectivity: Wireless data logging and report generation via the iENV app.

• Split-Type Sensor: Flexible positioning for shadow-free measurements.

• 20,000-Set Data Storage: Robust internal memory for longitudinal auditing.

• High-Resolution Backlit Display: Crystal-clear visualization of complex data.

• Relative Mode (REL): Instant comparison between current and reference light levels.

Professional Application Scenarios

• Workplace Safety Compliance: Auditing office and factory floor lighting to ensure adherence to OHS standards and improve worker productivity.

• Lighting Design Verification: Confirming that newly installed LED or HID systems meet the specified Lux requirements in commercial and public spaces.

• Photography and Cinematography: Providing precise light intensity data for optimal exposure and set lighting consistency.

• Energy Efficiency Audits: Identifying over-illuminated areas to optimize energy consumption and reduce operational costs.

• Agricultural and Greenhouse Monitoring: Measuring light intensity for optimal plant growth and greenhouse management.

Maintenance and Best Practices

To maintain the professional accuracy and longevity of your UNI-T UT381A, follow these protocols:

• Sensor Protection: The silicon photocell is a precision optical component; keep the sensor cap on when not in use and avoid touching the sensor surface to prevent oil and dust accumulation.

• Cleanliness: Periodically wipe the sensor lens with a soft, dry, lint-free cloth to ensure maximum light transmission and measurement accuracy.

• Calibration Verification: For high-stakes legal or safety compliance work, it is recommended to periodically verify the meter’s accuracy against a certified light source.

• Battery Care: Remove the batteries if the device will be stored for an extended period to prevent leakage and damage to the internal electronics.
