About This Product

■Summary

The B520 manufactured by LMT in Germany is the most accurate illumination meter on the market. It is possible to measure illumination from ultra-low illuminance of 0.0001 Lux to high illuminance of 600,000 Lux, and we offer various options such as a photometer head with temperature stabilization function and an outdoor photoreceptor. Programmable via RS-232 interface and compatible with class A and L acc.to DIN 5032 part 7.

■Features

・Achieves extremely weak light measurement and wide measurement range (0.0001 to 600,000lux) ・Applies to DIN5032 part 7 Class A/Class L grade as the highest quality laboratory illumination meter ・ASCII command control ・The spectral response of the light receiving part is corrected with high accuracy compared to the standard luminous efficiency (f1<0.8%) ・Built-in battery can be selected ・Can control two receivers ・World's highest level illuminance meter ・4 digit display ・7-step switching range ・Automatic or manual range ・Attenuator with precision potentiometer (optional) ・Power supply for receiver with temperature control function (optional) ・Analog output, RS232 interface, BCD data output (optional) ・Compact tabletop case ・Rechargeable battery specifications that do not require a power source can be selected (optional)

■Measurable units

Illuminance, brightness, cylindrical surface illuminance, semi-cylindrical surface illuminance

■Application

・Screen evaluation of various projectors ・Inspection of automotive lighting equipment and lights (headlights, taillights, turn signal lights) ・Extremely weak light measurement of fluorescence and reflection samples ・Outdoor extremely weak light measurement

■Display range

Range changes in steps and overloads are protected on all ranges

■Receiver

・P30SC0 with ultra-stable silicon diode, other versions available as options ・The main unit and receiver are connected using a LEMO® plug-in cable. ・Spatial evaluation: cosine collection, receiver for Ez or Esz (optional) ・Temperature control function: Optional ・Light receiving surface: 30mm in diameter ・Features: A test report is issued for the standard luminous efficiency V (λ) match result and cosine correction, and the receiver can be selected with a horizontal adjustment mechanism and level gauge.

■Calibration

・Recalibration period <2 years/PTB traceable for standard light source A and 25℃ - Relative expansion measurement uncertainty includes a standard uncertainty of 0.8%.
