Reid Vapor Pressure Bath

Reid Vapor Pressure Test Equipment

Professional-grade vapor pressure testing equipment designed for liquid petroleum products and liquefied petroleum gases (LPG). This comprehensive range conforms to ASTM D323, D1267, and related international specifications for Reid Vapor Pressure determinations. Vapor pressure measurements are critical for handling, performance evaluation, and regulatory compliance in petroleum products, particularly automotive gasolines subject to pollution control regulations.

Polished Stainless Steel Test Cylinders

These precision test cylinders accommodate vapor pressure testing of liquid petroleum products, volatile crude oil, and liquefied petroleum gases. Each cylinder features an upper chamber and lower chamber in the required 4:1 volume ratio, with O-ring gaskets providing tight seals between chambers and at gauge coupling.

The one-opening type is designed for gasoline and products with Reid Vapor Pressure below 26psi (180kPa). The two-opening type accommodates liquid products with Reid Vapor Pressure above 26psi (ASTM D323) and LPG testing (ASTM D1267). The lower chamber of the two-opening apparatus includes a straight-through ball valve and 1⁄4" needle valve. For LPG testing, order the two-opening type apparatus with the accessory bleeder valve assembly.

Shipping Weight: 7 lbs (3.2kg)

Included with each cylinder: Threaded 1⁄4" Gauge Coupling and O-ring Seals (2)

Reid Vapor Pressure Gauges

Ruggedly constructed Bourdon type gauges engineered specifically for Reid Vapor Pressure testing. These gauges feature heavy duty rotary brushed stainless steel movement and dual psi/kPa scale on a 41⁄2" diameter dial. The lightweight aluminum case has a corrosion-resistant finish, and the heavy duty brass non-sparking handle ensures safety during operation. Each gauge includes a micrometer adjustable pointer, blow-out disc, and 1⁄4" NPT male thread connection.

• Conforming to ASTM D323, D1267 and related specifications
• Dual psi/kPa scale on a 41⁄2" diameter dial
• Accurate to within 0.5% of scale range
• Micrometer adjustable pointer

Reid Vapor Pressure Gauge Specifications

Constant Temperature Water Baths

4-Unit Reid Vapor Pressure Bath

Designed for Reid Vapor Pressure determinations of liquid petroleum products and liquefied petroleum gases (LPG), this constant temperature water bath immerses vapor pressure apparatus at the proper depth per ASTM specifications. The microprocessor PID control provides quick temperature stabilization without overshoot and controls bath temperature with ±0.2°F (±0.1°C) precision. An overtemperature control circuit interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format.

The double-wall construction features a fiberglass insulated stainless steel tank. A sturdy 1" (25mm) flange permits flush-mount benchtop installation for easy access to the bath interior. Built-in holders suspend test cylinders at the required depth. Equipped with overflow stand pipe/drain.

• Conforms to ASTM D323, D1267 and related specifications
• Free standing or flush-mount benchtop installation
• Microprocessor programmable high accuracy temperature control

21-Unit Reid Vapor Pressure Bath

This constant temperature water bath immerses twenty-one test cylinders for vapor pressure tests on liquid products and liquefied petroleum gas (LPG). Electronic level control automatically maintains the proper immersion depth per ASTM specifications. The heating system employs a 6kW stainless steel heat exchanger with a heavy duty circulating pump to provide rapid heat-up, even heat distribution and ease of servicing. Convenient digital setpoint and display permits rapid selection of any bath liquid temperature within the operating range.

A built-in overtemperature limit control protects against accidental overheating. Bath interior and internal components are constructed of heavy gauge stainless steel. Control panel is shielded by a hinged acrylic cover. Includes sturdy angle-iron base with corrosion resistant polyurethane finish. Order pressure gauges and cylinders separately.

Wireless Reid Vapor Pressure Data Acquisition System

Windows®-based electronic pressure measurement software designed for ASTM Reid Vapor Pressure test methods. Monitors up to eight pressure vessel channels, graphing pressure and RVP data in real-time for each channel. Each channel can be run independently and configured for the pressure ranges of 0-50, 0-200, and 0-1000 psi. Pressure values can be reported in psi or kPa. Software automatically exports results into Microsoft® Excel for data analysis and storage.

Includes software, multiplexer box, USB converter box and RTD temperature probe. Requires one pressure transducer for each pressure vessel.
