The Cambridge 6860 685 Galvanometer is a high-quality, analog instrument designed for precise measurement of electrical current. This galvanometer features a 6.86-inch (174 mm) dial, which is large enough to provide clear, easy-to-read readings. The dial is graduated in both milliamperes (mA) and microamperes ( A), allowing for a wide range of current measurements.
The Cambridge 6860 685 Galvanometer is constructed using high-quality materials, including a brass frame and a fine-wire coil. The frame is polished to a mirror finish, giving the galvanometer a sleek and professional appearance. The coil is made of a fine, high-resistance wire, which allows the galvanometer to provide highly sensitive and accurate current measurements.
The galvanometer is powered by a small battery, which is included with the instrument. The battery is easily replaceable, ensuring that the galvanometer can be used for many years to come. The battery is located in a compartment at the back of the instrument, which can be accessed by removing a few screws.
The Cambridge 6860 685 Galvanometer is designed to be easy to use, with a simple and intuitive dial system. The dial can be set to either a full-scale deflection of 1 mA or 10 A, depending on the current being measured. The dial also features a zero-adjustment knob, which allows the user to set the zero-point of the galvanometer to the exact position they desire.
Overall, the Cambridge 6860 685 Galvanometer is a high-quality and reliable instrument for measuring electrical current. Its large dial, high-quality construction, and simple operation make it an excellent choice for a wide range of applications, from basic current measurements to more advanced scientific experiments.
