Experience unparalleled accuracy and flexibility in light level monitoring with the Sper Scientific 840022 Advanced Light Meter. Designed for professionals who demand precision, this meter delivers fast, stable, and incredibly accurate responses, making it ideal for a wide range of applications from industrial environments to photographic studios, and quality control.
Key Features & Benefits:
- Exceptional Readability: Instantly interpret results on the extra-large 1½" (38.1 mm) LCD. The intuitive bar graph provides a quick visual reference, while low battery and over-range indicators keep you informed.
- True-to-Life Readings: Equipped with a sophisticated color and cosine corrected sensor that adheres to the C.I.E. photopic spectrum, this meter ensures readings are true to actual lighting conditions. It's capable of accurately measuring LED light sources, a crucial feature in modern environments.
- Advanced Compensation: A unique and highly valuable feature allows you to compensate for the different color temperatures of various light sources—tungsten, fluorescent, mercury, and sodium lights—with a simple push of a button. This guarantees the most accurate measurements regardless of the light type.
- Data Management & Analysis:
- RS232 Computer Output: Connect to your PC for data logging, analysis, and report generation, enhancing your record-keeping capabilities.
- Min/Max Function: Easily capture and display the minimum and maximum light levels recorded during a measurement session.
- Peak Function: Instantly capture and hold the highest light intensity detected, perfect for transient light events.
- User-Friendly Design:
- Hold Function: Freeze the current reading on the display for convenient observation.
- External Zero Adjustment: Ensure consistent accuracy with easy recalibration.
- Auto Power Off: Conserves battery life, extending usage time.
- Tripod Back: Mount the meter for hands-free, stable measurements.
- Detachable Sensor: The sensor easily detaches and comes with a protective cover, simplifying replacement, repair, or allowing for measurements in hard-to-reach areas.
- Comprehensive Package: Your meter arrives ready for immediate use, complete with a 9V battery, detailed instructions, a soft padded carrying case with a shoulder strap for portability, and a N.I.S.T. traceable certificate of calibration, assuring its accuracy and adherence to national standards.
