Standard Features of REFCO<br />
R3 and R5 Class 1.0<br />
Bellow Gauges are:<br />
Bellow type gauges are extremely over-pressure resistant.<br />
A bellow type gauge can withstand up to 2.5 times overpressurization<br />
of the printed pressure scale without damage to<br />
the gauge.<br />
A bourdon tube gauge cannot withstand this type of over<br />
pressurization<br />
Class 1.0 accuracy<br />
Available in 2 3/4" (68 mm) or 3 1/4" (80 mm), both large and<br />
easy to read. PM series only available in 3" (76 mm)<br />
Zero point adjustable<br />
Silicone oil-filled, except PM series<br />
Aluminum anodized body for R3 and R5 series<br />
PM series is made with a fiberglass body<br />
Hermetically sealed, no oil fill plug on the top of the gauge to<br />
allow seepage or leakage for R3 and R5 series<br />
Color-coded for pressure and compound<br />
Standard 1/8" NPT bottom connection<br />
All brass or steel internal parts, no plastic<br />
Relief device on back of gauge in case of extreme overpressurization<br />
for R3 and R5 series<br />
Pressure and Vacuum Gauges<br />
General Information:<br />
Standard threaded connection - 1/8" NPT<br />
F = pressure scale on gauge in psi and temperature scale in degrees F<br />
Temperature scales:<br />
R12 = R12/R22/R502<br />
R22 = R22/R134a/R404A<br />
R134a = R134a/R404A/R507<br />
R410A = R410A<br />
R410A-FG = R410A/R134a/R22<br />
M2-500<br />
Pressure scales:<br />
R12, R22, R134a gauges:<br />
Low side 30" vacuum up to 120 psi, retard to 350 psi<br />
High side 0 psi up to 500 psi<br />
R410A:<br />
Low side 30" vacuum up to 500 psi<br />
High side 0 psi up to 800 psi<br />
