Feature:1. Applications: The instrument is designed for measuring illuminance, UV index, flicker frequency, color tolerance, color rendering index, correlated color temperature, temperature, humidity, and is suitable for lighting fixtures, outdoor, greenhouse and stage lighting, etc2. Light Source Analysis: Designed with spectrum sensor, this illuminance meter can simultaneously measure multiple parameters and display spectrum curves, identify the type of lighting fixture, and comprehensively evaluate the characteristics of the lighting source3. Accurate and Consistent: Using high accuracy spectrum sensor, suitable for human eye spectra, the spectrum response is completely consistent with the V () function, ensuring that the instrument has high measurement accuracy for measuring various colors of light4. Measurement Range: The illuminance measurement range is 0-1000000Lx, accurately measuring low light and strong light; Measurable correlated color temperature in the range of 1000-100000K, convenient for lamp development and lighting scheme design5. Flicker Measurement: This illuminance meter has a flicker measurement function, with a flicker frequency measurement range of 10-500HZ. It can evaluate whether the lamp meets the standard requirements based on the flicker frequency and fluctuation depthSpecification:Item Type: Spectrum Illuminance MeterIlluminance Wavelength Range: 400nm-700nmIlluminance Wavelength Interval: 10nmIlluminance Measurement Range: 0-1000000LxIlluminance Resolution: 0.1LxIlluminance Measurement Accuracy: (3%H+2Lx) H as standard value(calibrated under CIE standard A light source)Illuminance Optional Unit: Lx (Default), FCRelated Color Temperature Measurement Range: 1000-100000KRelated Color Temperature Measurement Accuracy: 5%UV Index Measurement Range: 0.0-15.0UV Index Measurement Accuracy: 0.5Flicker Frequency Measurement Range: 10-500HZFlicker Frequency Measurement Accuracy: 5%Temperature Measurement Range: -20-80Temperature Measurement Accuracy: 0.5Humidity Measurement Range: 0%RH-90%RHHumidity Measurement Accuracy: 4%RHResponse Time: <0.7sTest Light Hole Diameter: Approx. 21mm / 0.83inDisplay: 240x160 Dot Array LCDBattery: 2 x AA Alkali Dry Battery (not included)Using Environment: Temperature: 0-40, Humidity: <85%RH.Package List:1 x Illuminance Meter1 x User Manual
