Refco Gauges
Class 1 vs. Class 1.6 vs.Class 2 accuracy gauges
Class 1 gauges are accurate within +/- 1 percent reading all the way around the gauge dial. These gauges are the most accurate offered by REFCO. Class 1.6 gauges are accurate within +/- 1.6 percent reading all the way around the gauge dial. These gauges are also very accurate and are the standard accuracy gauge offered by REFCO. Class 2.0 gauges are accurate within +/-2 percent over the first 1/3 of the gauge dial, +/-3 percent over the next 1/3 of the gauge dial and then +/-2 percent over the last 1/3 of the gauge dial. This is commonly called 2-3-2 accuracy. These gauges are least accurate where most of the readings are taken.
REFCO uses as standard on manifolds Class 1.6 accuracy gauges and on higher end manifolds Class 1.0 accuracy gauges. Most competitors use as standard the Class 2 or 2-3-2 accuracy gauges. This makes REFCO manifolds more accurate. REFCO DOES NOT USE ANY CLASS 2 or 2-3-2 accuracy GAUGES ON ITS MANIFOLDS. Unlike many service tool suppliers REFCO manufactures their own gauges.
