Philip Harris Interscale Demonstration Meter

This demonstration meter is ideal for science teachers wanting to clearly illustrate electrical measurements to students. Designed for classroom use, it allows learners to observe both the readings and the inner workings of the meter, supporting practical understanding of electricity concepts. Suitable for secondary schools and colleges, it can be used as either a voltmeter or ammeter for both A.C. and D.C. by adding interchangeable dials (sold separately).

• Moving coil galvanometer for accurate readings (±2.5%)

• Scales visible on both sides for group demonstrations

• Transparent plastic case for easy observation of internal mechanisms

• Dimensions: 300mm (W) x 300mm (H) x 150mm (D)

• Basic sensitivity: 5 mA, 100 mV full scale deflection
