Pressure Gauges

Standard Refrigerant

Temperature Scales:

R12 = R12/R22/R502

R22 = R22/R134a/R404A

R134a = R134a/R404A/R507

R410A = R410A

R410A-FG = R410A/R134a/R22

Standard Pressure Scales:

R12, R22 and R134a gauges:

Low side 30“ vacuum up to 120 psi, retard protection to 350 psi

High side 0 psi up to 500 psi

R410A gauges:

Low side 30“ vacuum up to 500 psi

High side 0 psi up to 800 psi

REFCO Gauges

General Information

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⁄

the gauge dial, ±3 percent over the next ¹⁄

of the gauge dial and then

±2 percent over the last ¹⁄

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.
