Physics Teaching Equipment , Multifunctional Large Screen Digital Display Tester

Product information:

HT-J0416-1 multifunctional large screen digital display tester is an intelligentized multifunctional precise digital display measuring apparatus. Time measurement part of the apparatus has the function of measuring time, interval time, the speed of moving object in the collision experiment and cycle; accumulation counting and storing ten groups of data. Temperature measurement part of the apparatus can measure the temperature. Electrical measurement part can measure the frequency, resistance, alternating and direct current, voltage and so on. It is a common instrument special for school physics teaching use in experiments which is usually combined with the air track and small air supply to finish the general physics and related mechanics experiments. It can be also used in multi-digital instrument to finish the teaching experiment in electricity, at the same time it can be used as the professional measuring instrument.

This tester adopts the intelligent single-chip microcomputer technology, C language to write application program, the photoelectric sensor, silicon material thermosensitive device as the input of temperature measuring probe, LED large screen as digital display. It has many advantages like long distance within visibility, wide range of visual angle, accurate measurement; intelligentized conversion in place, low power consumption, high EFT, direct and clear display, easy operation etc.
