OPPLE LIGHTING Light Master IV luksimittari

The OPPLE LIGHTING Light Master IV is a professional-grade digital lux meter designed for precise measurement of illuminance in various environments. With a wide measurement range from 0.1 to 200,000 Lux, it is suitable for applications in lighting design, workplace safety, photography, and industrial inspection. The device features a silicon photodiode sensor with spectral response filter for accurate CIE photopic response, ensuring reliable readings that match human eye perception.

Advantages

High accuracy of ±3% rdg ±0.5% f.s. for readings below 10,000 Lux and ±4% rdg ±10 digits above 10,000 Lux. Auto-ranging function simplifies operation, while data hold and max/min hold allow for easy recording of measurements. The backlit 4-digit LCD ensures readability in low-light conditions. Auto power off after 15 minutes conserves battery life.

Suitable for

• Lighting professionals and engineers for field measurements
• Workplace safety inspections to ensure compliance with illumination standards
• Photographers and videographers for setting up lighting
• Industrial and laboratory environments requiring precise light measurement
