Digital Ohms Meter – 20Kohms
Product Code : SCL-IMIC-11428
Description:
The Educational Instruments Digital Ohms Meter is a compact and reliable piece of Physics Science educational laboratory equipment designed for the precise measurement of electrical resistance in circuits and components. With a maximum range of 20 kilo-ohms (20,000 Ohms), this instrument provides high accuracy required for educational and prototyping environments.
The meter features a clear LCD display for unambiguous digital readings and is powered by a standard 9 Volt internal battery, ensuring portability and ease of use in various lab settings. Constructed with a durable ABS plastic body and secure brass terminals, this device is built to withstand rigorous academic use.
Product Usage:
The Digital Ohms Meter is fundamental to teaching and executing experiments in electricity and basic electronics. Its primary application is to directly measure the opposition a material or component offers to the flow of electric current.
Ohm's Law Verification: This is a core experiment where the meter is used to accurately measure the resistance ($R$) of a circuit element (like a resistor) before voltage ($V$) is applied and current ($I$) is measured. This allows students to verify the relationship $V = IR$.
Circuit Analysis: Used to measure the total equivalent resistance of series and parallel circuits, allowing students to validate theoretical calculations and understand how resistances combine.
Component Testing: Essential for testing the integrity of electronic components such as resistors, wires, switches, and potentiometers.1 It can identify open circuits (infinite resistance) or short circuits (near zero resistance), which is a key diagnostic skill.2
Material Conductivity Studies: Can be employed to compare the resistance of different materials and wires, directly demonstrating the concepts of conductivity and resistivity as applied in physics.
The meter is highly accurate and is an ideal replacement for older, less precise analog meters, improving the quality of student data collection.
Educational Applications & Learning Goals:
This Digital Ohms Meter supports crucial hands-on learning in Physics, Electronics, and Engineering:
