Luminance Meter LS-150 measuring the brightness of a light source.
The Konica Minolta LS-150 is a luminance meter, a more specific type of light meter used to measure the luminance of a light source or reflected light. Luminance is measured in candelas per square meter (cd/m²), which is a unit of luminous intensity per unit area.
The LS-150 is a handheld, battery-powered meter that is easy to use and portable. It is a good choice for a variety of applications, including:
- Measuring the luminance of light sources, such as CRTs, LEDs, and EL displays
- Measuring the brightness of road and tunnel lighting
- Measuring the luminance of rail-system and road signs
- Measuring the illumination of outdoor signs
- Measuring the illuminance of illumination equipment and devices
The LS-150 conforms to the DIN 5032-7 Class B standard for luminance meters. This standard specifies the accuracy and performance requirements for luminance meters.
Here are some of the key features of the Konica Minolta LS-150 luminance meter:
- Wide luminance measurement range: 0.001 to 999,900 cd/m²
- Single lens reflex (SLR) optical system for accurate targeting of small measurement areas
- Bright viewfinder and backlit LCD screen for easy reading of measurement values
- Automatic mode that automatically sets the measurement time according to the brightness of the target
- Color correction and calibration functions
If you are looking for a high-quality, accurate, and easy-to-use luminance meter, the Konica Minolta LS-150 is a great option. Contact us for a demonstration.
