When choosing a meter, its measuring range should be used. For short distance measurements, use devices with a range beginning with a large positive value, and for long distance measurements, the range should end with large negative values. The Extralink WT-3053 Optical Power Meter with a range of -70~+3dBm is the perfect choice for precise measurements of very weak light sources.
