Key benefits Reliable data capture: automatic storage holds up to 2000 groups of illuminance readings and manual storage supports up to 60 groups, so you can keep complete measurement records without constant notetaking. Simplified operation: Auto range technology automatically confirms and converts the correct measurement range, reducing setup errors and letting you focus on results instead of range selection. Accurate in low light and fast events: The meter responds quickly to changes in light and reliably detects lowlight conditions, making measurements more precise for challenging environments. Usable anywhere: The backlit screen makes the meter easy to read and operate in dim or dark settings. What this product solves Eliminates manual logging and reduces the risk of missed or inconsistent data by providing large automatic and manual storage capacity. Reduces user error and speeds up testing by automatically selecting the appropriate measurement range. Captures transient or lowlevel lighting conditions with fast response, improving measurement reliability for inspections and quality checks. Enables measurement in poorly lit locations without additional lighting or guesswork. Core functions and performance Data storage: automatic mode (up to 2000 groups), manual mode (up to 60 groups). Auto range: automatically detects and switches to the corresponding measurement range for straightforward, accurate readings. Responsiveness: designed to detect rapid changes and low illuminance levels with precision. Display: backlit screen for clear visibility in dark or lowlight environments. Compatibility and applications Works across a broad range of lighting environments and measurement tasks where illuminance monitoring is required. Suitable for use by facilities managers, technicians, photographers, safety inspectors, and maintenance teams. Typical use scenarios Workplace lighting inspections: quickly verify office, factory, or school lighting levels to meet standards and document readings with stored data groups. Photography and studio setup: confirm illumination and make repeatable measurements for controlled lighting conditions, including lowlight scenes. Facility maintenance and quality control: monitor warehouse, display, or exhibit lighting over time and retain measurement logs for audits or troubleshooting. Why choose this meter Designed for practical field and indoor use with large onboard storage, automatic range selection, fast response for lowlight accuracy, and a backlit display for dark conditions. These features combine to reduce setup time, lower user error, and provide reliable records of illuminance measurements.
