Electricity Galvanometer Measure very small amounts of current supplied by your voltaic cell or magnetic induction experiment. P4-1207 +/-500 mA (milliamps) $19.50 P4-1208 +/-500 μA (microamps) $19.50 See www.arborsci.com for suggested uses of each range. Easy-to-use, versatile meter does double duty. Instantly switch from volts to amps. Get two meters for the price of one Analog student meter measures voltage or current! Just slide the terminal cover to convert from volts to amps. Lightweight, portable, and convenient. Just check out two meters to each student group for all of their electronics measurements. Electrodes and Voltaic Cell The voltaic cell is ideal for demonstrating the characteristics of a primary cell. The clear plastic cup allows you to easily view the electro-chemical reactions taking place. Sturdy nickel plated clamps hold both round and flat electrodes. A porous cup is also included. The unit measures 95 mm diameter x 120 mm height. Includes plastic cup, porous cup and 8 electrodes: one each flat aluminum, copper, brass, iron, zinc, nickel, tin, carbon. Instructions provided. Voltaic Cell and Electrodes $30 Electrodes (Single,125 mm x 25 mm) P6-2610 Aluminum $1 P6-2611 Copper $1.50 P6-2612 Iron $.85 P6-2613 Zinc $1.25 P6-2614 Carbon rod (5 mm dia) $1.75 P6-2620 Class pack $55 Contains 10 each of aluminum, copper, iron, zinc and carbon P6-2605 The unit has a special safety feature that prevents mis-wiring by students. The auto switching mechanism covers the unused terminals for volts or amps when the other is in use. The meter also clearly indicates which function is in use when the switch is moved. • Dimensions: length 16.5 cm x 11.3 cm • Voltage range: 0 mV, 100 mV, 1 V, 10 V, 50 V • Amperage range: 0 μA, 100 μA, 100 mA, 1 A, 5 A P6-8020 Dual Ammeter/Voltmeter $20 6 or more $18 each Introductory Teacher’s guide sold separately.
