Review HOYT Vintage Model Volt Ammeter 60a 20v Meter Bakelite Case

The Hoyt GT-20 Volt Ammeter is a classic and reliable instrument for measuring both voltage and amperage in electrical systems. This model features a 60 A, 20 V full-scale dial, making it suitable for measuring currents and voltages within a wide range. The ammeter is housed in a bakelite case, which is known for its durability and heat resistance.

The GT-20 Ammeter boasts a high-quality, easy-to-read dial with a black face and white pointers. The dial is graduated in amperes and volts, with clear markings for each unit. The ammeter also comes with a shunt, which is used to measure currents above the ammeter's internal rating. The shunt is calibrated for 60 amperes and can be easily installed in the circuit to measure higher currents.

The GT-20 Ammeter is designed with a high impedance, which allows it to measure voltages without significantly affecting the electrical circuit. It also features a protective fuse, which safeguards the instrument against overloads and short circuits. The meter comes with both a red test lead for measuring current and a black test lead for measuring voltage.

The bakelite case of the GT-20 Ammeter not only adds to its vintage appeal but also provides excellent protection against impact and moisture. The dial is shielded from direct sunlight, ensuring accurate readings even in bright conditions. The ammeter is also designed with a waterproof seal on the test lead terminals to prevent moisture from entering the instrument.

The Hoyt GT-20 Volt Ammeter is an essential tool for anyone working on electrical systems, from automotive mechanics to electricians. Its robust construction, high accuracy, and versatility make it a valuable addition to any toolkit. Whether you're troubleshooting a car's electrical system or installing a new electrical circuit, the GT-20 Ammeter is an indispensable companion.
