Loos Gauge Cross Reference

Cross reference of readings between the Model A, Model B, PT-1, PT-2, and PT-3 gauges. If you know the desired reading on one gauge but own another, this will give you your target reading for the gauge you have. The second table will give tension numbers for the PT series of gauges.
