Digital illuminance meter with a maximum display of 199,900 lx Features Capable of a broad range of measure- ments, from low light levels to strong light levels. Permits remote measurement with the sensor separated from the main unit. Equipped with display hold and backlight features. Simple operation. Includes analog output that can be used to record results. Analog output includes zero adjustment function. The 3423 is an easy-to-operate handheld unit that can measure a broad range of luminosities, from the low light provided by induction lighting up to a maximum intensity of 199,900 lx. This device is suited for a wide range of applications involving illumination equipment, lighting work, and facility management. Measures a broad range of luminosities with simple operation Using the display hold and backlight features, it is easy to take readings even in dark locations. Because the backlighting turns on only after the display is held, the backlighting has no effect on the measurements. When zero adjustment is performed for the display, it is performed for the analog outputs simultaneously. Human perception of brightness differs according to the wavelength of the light and also varies among individuals. As a result, the International Commission on Illumination (CIE) has established comparative standards for luminosity. Although ideally relative spectral response would be equal to these standards, the 3423 has excellent characteristics that are close to the comparative standards for luminosity.
