Standard: ASTM D323, D1267
Measures the vapor pressure of automobile and aviation gasoline, petroleum products and crude oils.
• Conforms to ASTM D323, D1267 and related specifications
• RVP bath provides high accuracy programmable temperature control
Vapor pressure is a critical factor in the handling and performance of
liquid petroleum and liquefied petroleum gas products. The vapor
pressure of automotive gasoline is subject to governmental regulation
for pollution control purposes.
1) RVP Bath controls temperature with ±0.2°F (±0.1°C) precision, and
determines vapor pressure of gases by immersion of vapor pressure
cylinders at the proper depth per ASTM specifications. Dual LED displays
provide actual and set-point temperature values in °F/°C format. Holds
up to four pressure cylinders. Bath is made of a double-wall
construction with fiberglass insulated stainless steel tank. A sturdy 1'
(25mm) flange permits flush-mount bench-top installation for easy
access to the bath interior.
2) RVP Gauges have a large easy-to-read 4-1/2" (11.4 cm) diameter dial.
Accurate to ±0.5% of scale range. Gauges feature an aluminum case with
brass handle, blow-out back, and 1/4" NPT(M) connection. Sold
separately.
3) RVP Cylinders have polished stainless steel construction. Use
one-opening cylinder to test gasoline and other products having a vapor
pressure below 26 psi. Two-opening cylinder is for liquid petroleum
products and liquefied petroleum gas products (LPG) with a vapor
pressure above 26 psi. The two-opening cylinder includes
straight-through ball valve and a needle valve. For LPG testing, order
the bleeder valve assembly for use with the two-opening cylinder. Sold
separately.
