METER: Large Demonstration (300 x 150 x 300 mm) | Useful for science applications

$ 10.50$ 225.00 excl. GST


Housed in an ABS plastic case 300 x 150 x 300 mm. Moving coil has accuracy of +/-2.5%. Basic sensitivity is 5mA and 100mV at full scale deflection.
Can be used as an AC or DC ammeter or voltmeter. Interchangeable dials with their own series resistors, shunts or rectifiers can be purchased to convert it to a number of ranges.
Movement can be centre zeroed when used as a galvanometer.

Supplied with the following dials:
• 2.5 – 0 – 2.5mA, • 0 – 1A/DC,
• 0 – 10A/DC, • 0 – 5-volts/DC,
• 0 – 15-volts/DC, • 0 – 100mV/DC.

(Wikipedia excerpt:…”…An ammeter (A) ….. is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. The (A) is usually connected in series with the circuit in which the current is to be measured. An (A) usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured.

Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milli (A) or micro (A) . Early (A) were laboratory instruments that relied on the Earth’s magnetic field for operation. By the late 19th century, improved instruments were designed which could be mounted in any position and allowed accurate measurements in electric power systems. It is generally represented by letter ‘A’ in a circuit.”)
