PM200J Phosphor Relative Brightness Test Meter is work with PB-2 phosphor excitor to test the relative brightness of phosphor. The relative brightness is a ratio of standard phosphor and testing phosphor which have been excited by the steady ultraviolet. The instrument is a perfect test device for phosphor manufacturer as it's high precision and easy to operation and display the brightness directly.

Characteristics and specifications:

◎Many types phosphor measurable
◎Auto range switch
◎Low zero drift,high accuracy
◎Work together with PB-2 phosphor excitor

Products Introduced:

This test system is suitable for energy-saving lamp, fluorescent lamp, HID lamp (high voltage sodium lamp, high voltage mercury lamp), phosphor photometry and colorimetry analysis and meets the requirements of CIE for the measurement of photometry and colorimetry

Characteristics and specifications:

◎　Measure and display the relative spectral power distribution （UV-VIS-NIR）P(λ),
　　chromaticity coordinate, correlated color temperature, rending index, color difference,
　　peak wavelength, luminous flux, luminous flux efficiency and photometry parameters of light
　　source and light material under the control of general PC.
◎　Fast auto adjust high-voltage not only the mearsurement time quickly,but also the wear and tear of the instrument.
◎　Measure the temperature in both environment and integrating sphere simultaneously to make the data more visually and reliably.
