Introduction
It used for determining Planck’s constant is used to demonstrate the photoelectric effect, The filter adopts high-grade integrated operational amplifier and special circuit design, high-performance photoelectric tube, and the dial is a filter structure with novel design and complete functions.
Photocell sensitivity ≥ 1mA / LM, dark current ≤ 10A; zero drift ≤ 0.2% (full scale reading, 10a gear, after 20 minutes of preheating, measured within 30 minutes under normal environment); 3.5-bit LED display, the minimum current display is 10a, the minimum voltage display is 1mV, so the “zero current method” or “compensation method” can be used to accurately measure the cut-off voltage
