A&M Ruggedized Meters conform to the requirements of MIL-M-10304. A&M Instrument can identify and supply Meters to National stock numbers (NSN): Classes 1430, 4935, 5840, 6115,6645, 6665,and 6685. In addition A&M can supply Meters to Defense Agency Specification Prints for the US Army, US Navy, and US Air Force. Ruggedized meters are ideal for use in field communications or test equipment where severe environmental conditions are encountered. In industrial applications where moisture, extreme temperature or vibration may be a problem. The expanded scale technique of eliminating the unused portion of the scale and expanding the selected range to the full spread of the scale can easily be applied to these Ruggedized Meters. Accurate readings (0.5%) or better with improved resolution and readability are now available for adverse environments. Expanded scale meters are available as Voltmeters, Ammeters, and Frequency Meters. |
