Engine Temperature gauge used on many different military diesel generators including 5, 10, 15, 30, 60, 100, 200 KW generators. Essentially the entire TQG series uses this engine temperature gauge. The original military manufacturers (Beede Faria) no longer make this model meter. We have found an even higher quality civilian meter that operates in the same temperature range to deliver very accurate readings. Please note THIS IS NOT A MILSPEC unit, but a functional equivalent, so no certificate of compliance with a milspec (i.e. Beede) number will be provided.
