UNI-T UT383S Digital Light Meters

Split-Sensor Precision Photometer: Equipped with an extensible coiled cable connecting the illuminance sensor probe to the main unit, allowing easy light measurements in tight or hard-to-reach spaces.

Dual Unit Lux & Foot-Candle Measurement: Measures ambient light intensity from 0 Lux to 199,900 Lux (0 - 19,990 FC) with rapid 0.5s sampling speed.

Silicon Photoelectric Sensor Technology: High-precision optical filtering sensor accurately quantifies indoor and outdoor illuminance levels without spectrum distortion.

Max/Min Value Tracking & Data Hold: Features dedicated MAX/MIN tracking modes to isolate light peaks and minimums alongside a HOLD key to freeze real-time readings on screen.

Backlit LCD Screen & Over-Range Warning: High-contrast illuminated screen ensures easy reading in dark or overly bright environments and alerts users with "OL" when light levels exceed range limits.

Auto Power-Off & Energy Saver: Shuts down automatically after 5 minutes of inactivity to extend battery life during field surveys.

Housing & Sensor Construction: High-impact ABS plastic body casing with a flexible spring cable and a precision silicon photodiode sensor with protective lens cap.

Technical Specifications:

Measurement Range: 0 Lux - 199,900 Lux (0 FC - 19,990 FC).

Measurement Accuracy: -+ 4% + 8 digits (< 10,000 Lux); -+ 5% + 10 digits (> 10,000 Lux).

Sampling Rate: 0.5 seconds.

Power Supply: Powered by 3 x 1.5V AAA batteries.

Usage Advice: Place the light sensor directly beneath the light source perpendicular to the beam for maximum measurement accuracy. Attach the protective sensor cover when storing.

Maintenance & Cleaning: Keep the optical diffuser lens clean and free of fingerprints or dust using a soft microfiber cloth.

Essential Environmental & Architectural Photometer: Position as a primary light intensity meter for greenhouse growers, photo studio technicians, lighting designers, workplace safety auditors, and solar installers.

Highlight Split Probe Flexibility & Dual Units: Emphasize its extensible cable probe as a major functional upgrade over rigid single-body light meters when measuring overhead or hard-to-reach fixtures.

Recommended Cross-Sell Add-ons: Pair with UNI-T UT363S Digital Mini Anemometer, UNI-T UT353 Sound Level Meter, UT333S Temperature Humidity Meter, and DL8003 12-240V AC.DC digital test pen.
