Several conductor plates.
Tank.
Red conductor cable with banana crocodile.
Black conductor cable with banana crocodile.
Black cables ( 2 units) with bananas at the ends.
Red cables ( 2 units) with bananas at the ends.
The teacher can use any element that creates ELECTRICAL FIELDS, so the UNIT IS OPEN and can do MANY OTHER EXPERIMENTS.
c) Computer Control Software:
Computer Control+ Data Acquisition+ Data Management Software for Electrical Fields application.
Compatible with actual Windows operating systems. Graphic and intuitive simulation of the process in screen.
Compatible with the industry standards.
Registration and visualization of all process variables in an automatic and simultaneously way.
Flexible and open software, developed with actual windows graphic systems, acting simultaneously on all process parameters.
Management, processing, comparison and storage of data.
Sampling velocity up to 250, 000 data per second.
Student calibration system for all sensors involved in the process.
It allows the registration of the alarms state and the graphic representation in real time. Comparative analysis of the obtained data, after the process and modification of the conditions during the process.
Open software, allowing to the teacher to modify texts, instructions. Teacher s and student s passwords to facilitate the teacher s control on the student, and allowing the access at different work levels.
This unit allows that the 30 students of the classroom can visualize simultaneously all results and manipulation of the unit, during the process, by using a projector.
