Bill I like the CDI product line <http://www.cditorque.com/> and use a dual scale dial indicator model for larger fasteners and their driver for smaller electrical connections. Good quality and pricing. They contract produce for SnapOn ( owned by them now) and have had their own line now for quite awhile. I prefer the dial indicator over click style to keep from over torquing the connection, especially stainless on aluminum rails! They also sell calibration tool that you can use in the shop to check when you might need to send it in for re-calibration. I believe that it is not as critical with the dial indicators because it is using a bending beam to measure rather than a spring clik mechanism. Since I do 3rd party commissioning I do check my calibration at the shop before after each job to insure accuracy. It is becoming common practice to check torques on electrical connections by using a thermal camera while under loads to identify connections that need re-torquing to keep from over torquing and busting off connectors. Loose connections show a significant higher temperature than tight ones.
