Product Description
The K11450 4-unit Reid Vapor Pressure Bath is a Constant temperature water bath designed for Reid Vapor Pressure determinations of liquid petroleum products and liquefied petroleum gases (LPG). Vapor pressure is a critical factor in the handling and performance of liquid petroleum and liquefied petroleum gas (LPG) products. The vapor pressure of automotive gasolines is subject to governmental regulation for pollution control purposes. This unit immerses vapor pressure apparatus at the proper depth per ASTM specifications. Controls bath temperature with ±0.2F (±0.1C) precision. Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by an overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in C/F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Labequip representative for information. Double-wall construction with 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.
