Midziyo yeLADP-15 yekuona Planck's Constant (Software Optional)

Kuedza

1. Yera voltage yekucheka woverenga kuti uwane constant yaPlanck.
2. Yera photocurrent ye phototube uye ita kuyedza kwe photoelectric effect.

Main technical parameters
1, huwandu hwe microcurrent: 10-6 ~ 10-13A huwandu hwemafaira matanhatu, matatu nehafu display yedhijitari, zero drift ≤ mazwi maviri / min.
2, kana uchitenderedza diaphragm, hazvizofambise sefa yemavara, maviri acho anogona kutenderedzwa ari ega, hapana kupindirana, kunzwa kureruka, kuri nyore kushandisa, uye kudzivirira chiedza chakananga.
3, fotosero: yakaiswa mubhokisi rerima refotosero, simba rekushanda: -2V ~ +2V; -2V ~ +30V
mafaira maviri, ane kugadzirisa kwakanaka; kugadzikana ≤ 0.1%.
4, phototube spectral response range: 340 ~ 700nm, cathode sensitivity ≥ 1μA, rima current <2 × 10-12A, anode: nickel ring.
5, sefa yemavara: 365.0nm; 404.7nm; 435.8nm; 546.1nm; 578.0nm.
6, kusanganisira rambi remercury rine simba guru uye simba remagetsi remercury, simba remwenje wemercury 50W.
7, kukanganisa kwe h kukosha uye theoretical kukosha: ≤ 3%.
8, mhando ye microcomputer inogona kubatanidzwa ne USB interface kukombiyuta kuti iedze, pasina kombiyuta.
