HP821 LED Luminous Intensity & Electrical Meter is a cost-effective measuring instrument for measuring electrical characteristics and luminous intensity of LED. This tester can be competent for measuring the low and high power LED.
Measures:
Forward Voltage(VF), Reverse Current(IR), Luminous Intensity(IV), Intensity Angle(2θ1/2), Misalignment Angle(Δθ), Luminous Flux(ΦV)
Features:
- Built-in adjustable DC constant current power supply, output current up to 2000mA
- Turning dial by hand to measure the averaged LED intensity and intensity angle
- Be coupled to an integrating sphere for total luminous flux measurement
- Meets recommended geometry from CIE Pub. No. 127 Condition A and Condition B
Specifications:
- Forward Current IF: 0.1mA ~ 800.0mA (±0.5%)
- Reverse Current IR: 0.1μA ~ 200.0μA (±1%)
- Forward Voltage VF: 0.1V ~ 20.0V
- Luminous Intensity IV: 10.0mcd ~ 300.0cd (±8%)
- Intensity Angle 2(θ1/2): -90°~ +90° (0.5°)
- Luminous Flux ΦV: 0.1mlm ~ 2000.0lm (works with integrating spheres)
