HKL-323 Automatic Reid Vapor Pressure Bath
Overview
HKL-323 Automatic Reid Vapor Pressure Bath conforms to ASTM D323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). The liquid chamber of the vapor pressure apparatus is filled with the chilled sample and connected to the vapor chamber that has been heated to 37.8 °C (100°F) in a bath. The assembled apparatus is immersed in a bath at 37.8°C (100°F) until a constant pressure is observed. The reading, suitably corrected, is reported as the Reid vapor pressure.
Features
The instrument uses a temperature controller imported from Japan that is easy to operate and has a clear display for reading. Besides one of the most precise temperature control accuracy being ±0.1℃, also has features for safety and automation such as an over-temperature alarm and self-adjusting PID parameter.
The Reid test bomb moves on its own by turning and moving side to side. Turning once every 20 seconds and then going back at the same speed. This pattern continuously repeats for automated oscillation.
This instrument has a horizontal layout. A digital pressure gauge indicates the test pressure.
Both the water bath tank and the vapor pressure test bomb are fabricated using stainless steel which provides a high degree of resistance to rust.
This electrical water bath for heating includes a circulation motor to make sure the temperature is the same, with a variation inside the bath of less than 0.1℃.
The vapor pressure test bomb is composed of two chambers of equal inner diameter in a cylindrical body—the air chamber and the gasoline chamber. The volume ratio of the two chambers is from 3.95 to 4.05, which makes sure that the sample data are accurate.
The bath has in its features two Reid test bombs, which will permit running tests on samples side by side on the very same instrument.
The test bomb is linked to the pressure sensor through a quick-release coupling that guarantees not only quick and easy operation but also strong gas tightness.

FAQ
Q1: What is the significance and use of HKL-323 Automatic Reid Vapor Pressure Bath？
A: The vapor pressure plays a major role in automotive and aviation gasoline. It determines the ability of gasolines to start and warm-up engines as well as the difficulty to vapor lock when the operating temperatures are high or in high altitude situations. The maximum vapor pressure limits for gasoline are set by law in some regions as an air pollution control measure. Crude oil vapor pressure is an important subject to both the crude oil producer and the refiner. They use it when handling the crude oil and the initial treatment of the refinery. Also, vapor pressure serves as an indirect method of determining the evaporation rate of volatile petroleum solvents.
Q2: What standards does this product (HKL-323 Automatic Reid Vapor Pressure Bath) comply with?
A: HKL-323 Automatic Reid Vapor Pressure Bath conforms to ASTM D323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). The chilled sample is filled into the liquid chamber of the vapor pressure apparatus and this is set up with the vapor chamber which is heated to 37.8 °C (100°F) in a bath. The whole apparatus is placed into a bath at 37.8°C (100°F) till a stable pressure is obtained. The adjusted reading is given as the Reid vapor pressure.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The smallest order we can take is one unit. We will deliver your order roughly 20 days after we receive the payment in advance.
Q4: Do you provide product operation manuals or technical documentation?
A: Yes. Among other ways, we communicate with our customers through electronic transmission of product manuals, quick operation guides, application cases, and standard operating procedures (SOPs). You can get these either by logging to the download center at our official website or by getting in touch with customer service to ask for them.
Q5: Do you provide online training services?
A: If you need assistance, we are ready to provide you with online installation and commissioning services. At the same time, we will give you a thorough operation training. Besides that, we provide round-the-clock online training support for the end users all year long.
