FAQ
Educational meters are designed to be used in labs to measure various scientific quantities, such as voltage and current.
The desk stand voltmeter works by displaying the measured electrical voltage in a circuit on a clear screen. This allows students to understand electrical concepts easily.
An educational portable voltmeter measures voltage in a circuit whereas an educational portable ammeter measures electric current. Both of these meters are used in labs by students, helping them grasp fundamental principles.
Educational meters are suitable and easy to use for practical experiments. These meters allow students to conduct hands-on activities, collect data, and analyze results in subjects like physics and chemistry.
