LUX HiTESTER 3423 Field measuring instruments Digital illuminance meter with a maximum display of 199,900 lx Features Capable of a broad range of measurements, 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. Measures a broad range of luminosities with simple operation 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. 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. By using the 9436 connecting cable (with case), it is possible to take measurements with the sensor separated from the main unit. (The 9436 connecting cable is sold separately.) 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. 3243 relative luminous spectral luminous efficiency wave length (nm) relative spectral responsivity Specifications Auto range Manual range :5 seconds or less :2 seconds or less Display LCD 3 1/2 Maximum:"1999" However, in the 20,000 lx range, the maximum is "19,990", and in the 200,000 lx range, the maximum is "199,900".
