The General Electric D-70210-D and D-70202-A I-70-D Meters are antique automatic electrical measuring devices that were originally designed and manufactured for use during World War II. These meters were produced by the General Electric Company, a renowned American multinational conglomerate specializing in various industries, including energy production and electrical equipment.
The D-70210-D and D-70202-A I-70-D Meters are identical in design and functionality, with the primary difference being their external casing colors. The D-70210-D features a dark green painted finish, while the D-70202-A comes with a light olive drab painted finish. These meters were designed to withstand the rigors of military use and were commonly found in various military installations and on naval vessels during the war years.
Measuring approximately 10 inches in height, 6 inches in width, and 3 inches in depth, these meters are compact yet robust. The meters have a circular dial face with a black background and white markings that display the electrical measurements. They are designed to measure current, voltage, and power in alternating current (AC) electrical circuits.
The D-70210-D and D-70202-A I-70-D Meters feature a unique automatic mechanism that allows them to measure electrical parameters without the need for external switches or levers. This makes them ideal for use in applications where manual intervention may not be possible or desirable. The meters also have a built-in fuse protection system that helps safeguard against electrical overloads and short circuits.
The meters are housed in a sturdy and durable metal casing that is resistant to shock and vibration. They also come equipped with protective glass coverings over the dial faces to shield them from dust, debris, and accidental impacts. The meters require a 115V AC power source for operation and have a maximum current rating of 5 amps and a maximum voltage rating of 600 volts.
The D-70210-D and D-70202-A I-70-D Meters are not only historical artifacts but also functional electrical measuring devices that can still be used in various applications, such as in antique electrical systems, educational institutions, or even as decorative pieces in vintage electrical displays. Their unique design, robust construction, and historical significance make them a fascinating addition to any collection of antique electrical equipment.
The GE (General Electric) Army WWII D-70210-D and D-70202-A I-70-D meters are antique automatic electrical testing instruments that were originally used during the World War II era. These meters are known for their durability and accuracy, but like any other purchase, they come with their own set of pros and cons.
Pros:1. Historical Value: These meters are a piece of history and can be a great addition to a vintage electrical collection.
2. Durability: Being built during the 1940s, these meters were designed to last. They are made of heavy-duty materials and can withstand rough handling.
3. Accuracy: These meters are known for their accuracy and reliability in measuring electrical currents, voltages, and other electrical parameters.
4. Manual Operation: Unlike modern digital meters, these meters do not require batteries or any external power source to operate. They are self-contained and can be used anywhere.
Cons:1. Limited Functionality: These meters are not as versatile as modern digital meters. They can only measure a limited range of electrical parameters.
2. Requires Calibration: These meters may require regular calibration to ensure accurate readings. Calibration can be time-consuming and expensive.
3. Maintenance: Due to their age and complex mechanical design, these meters may require more maintenance than modern digital meters.
4. Limited Availability: These meters are no longer in production, and spare parts may be difficult to find.
Ending Conclusion:The GE Army WWII D-70210-D and D-70202-A I-70-D meters offer historical value, durability, accuracy, and manual operation. However, they also come with limited functionality, the need for regular calibration, maintenance, and limited availability.
Recommendation:If you are looking for a vintage electrical testing instrument for historical value or for specific applications where accuracy and durability are paramount, then these meters could be a good investment. However, if you need a versatile and easy-to-use meter for everyday electrical testing, then a modern digital meter would be a better choice. Additionally, it is important to consider the cost of maintenance and calibration before making a purchase.
