DT-1309照度计产品介绍（中文）
DT-1309是一款多功能数字式光度计，采用紧凑耐用的结构设计，操作简便，适用于测量光照强度（单位：勒克斯/尺烛光）。该仪器的探测头由高稳定性硅光敏二极管和光谱响应过滤器组成，能对不同角度的入射光进行有效补偿和校正，确保测量数据的准确性。设备具备400,000Lux/Fc的大测量范围，并可通过USB接口实现与计算机的数据传输及分析功能。其特点包括快速响应、自动量程切换、Lux与Fc单位自由转换、20分钟无操作自动关机等实用功能。40段模拟条带背光LCD显示屏可清晰显示测量值，适合在办公室、图书馆、医院、酒店等多种环境中使用。仪器内置峰值锁定功能，可捕捉持续时间超过10μs的光脉冲信号，并对非标准光源参数进行自动修正。工作环境要求为0~40℃温度及80%以下湿度，由一节9V电池供电。[1][3][5][8]
DT-1309 Light Meter Product Introduction (English)
The DT-1309 is a portable digital photometer featuring a robust yet compact design for convenient light intensity measurement in Lux/Foot-candle units. Equipped with a silicon photodiode detector and spectral response filter, it provides accurate readings with angular compensation for varied light sources. The device offers a wide measuring range up to 400,000 Lux/Fc with auto-ranging capability, complemented by a 40-segment analog bar graph and backlit LCD display. Key functionalities include real-time data sampling (1.5 times/sec), relative measurement mode, peak value capture for pulses above 10μs, and automatic parameter adjustment for non-standard light sources. The integrated USB port facilitates data transfer to computers for further analysis. Designed for versatility, it operates on a 9V battery within 0-40℃ temperature range and is suitable for applications including office lighting assessment, library illumination monitoring, and horticultural light measurement. The unit automatically switches between Lux/Fc units and enters power-saving mode after 20 minutes of inactivity.[1][7][17][26]
