With a complete scientific quality management system, good quality and good faith, we win good reputation and occupied this field for Work Functio, Planck Constant, Reflective Holography, We always regard the technology and prospects as the uppermost. We always function hard to make terrific values for our prospects and give our customers far better products and solutions & solutions.
China Wholesale Raman Factory – LADP-15 Apparatus for Determining Planck’s Constant-Basic Mode – Labor Detail:

This instrument uses strict isotropic technology, which greatly reduces the influence of interference currents and electrostatic fields and improves the measurement response speed. The actual measured Planck constant is stable, fast response and high accuracy.

You can purchase software to upgraded to computer type.

Experiments

1、Measure the cut-off voltage and calculate to get Planck’s constant.
2、Measure the photocurrent of the phototube and conduct the experiment of photoelectric effect.

Main technical parameters
1, microcurrent range: 10-6 ~ 10-13A a total of six files, three and a half digital display, zero drift ≤ 2 words / min.
2, when rotating the diaphragm, will not drive the color filter, the two can be rotated independently, no influence on each other, feel light, easy to use, and avoid direct light phototube.
3, photocell: placed in the photocell dark box, working power range: -2V ~ +2V; -2V ~ +30V
two files, with fine tuning; stability ≤ 0.1%.
4, phototube spectral response range: 340 ~ 700nm, cathode sensitivity ≥ 1μA, dark current <2 × 10-12A, anode: nickel ring.
5, color filter: 365.0nm; 404.7nm; 435.8nm; 546.1nm; 578.0nm.
6, including high-pressure mercury lamp and mercury lamp power supply, mercury lamp power 50W.
7, the error of h value and theoretical value: ≤ 3%.
8, microcomputer type can be connected by USB interface to the computer for experiments, without computer.
