China Wholesale CCD Spectrometer Manufacturers – LADP-13 Apparatus of Millikan’s Experiment (Computer controlled) – Labor

Features of the instrument
LADP-13 Millikan oil drop meter is developed and designed based on LADP-12, the system of the technical indicators and experimental parameters, the index of the scoreboard, brightness, contrast, oil density, viscosity coefficient, the local acceleration of gravity, etc. can be freely set. Click “Experimental operation”, the display enters the experimental operation interface, the voltage value and timing value are displayed on the LCD screen, calculate and print the experimental results and errors.
Instrument appearance and panel labeling and LADP-12 type oil droplet meter is the same.
Instrument composition  
The complete set includes: a Milligan oil droplet meter with panel labeled as P67101, graphic card, software, signal cable, earphone, etc.,. Computer is not included.
