This meter is a high accuracy meter with zero middle.
The Tekpower TP203 DC Galvanometer detects electric current within a range of -500-0-500µA and a reading accuracy of + or - 3.0%. The scale length is 2.5"X 4". The galvanometer comes with an external calibrating screw. It has light blue housing and rubber host. A galvanometer is used for classroom demonstrations and experiments, and is not protected against prolonged or significant overload.
Science education products incorporate applied math and science principles into classroom and home school-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.
