Vapor Pressure

Introduction

A vapor pressure tester measures the volatility of liquids under controlled conditions. It is widely used in petroleum and chemical industries. The system helps evaluate evaporation characteristics and storage safety of liquid samples.

Standards

ASTM D323-Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method)

ASTM D5191-Standard Test Method for Vapor Pressure of Petroleum Products (Mini Method)

ASTM D4953-Standard Test Method for Vapor Pressure of Gasoline and Gasoline-Oxygenate Blends (Dry Method)

ISO 3007-Petroleum products and crude petroleum-Determination of vapour pressure (Reid method)

Complies with the above standards, but is not limited to them.

Features

1. Multiple sample positions process several specimens in a single run.

2. Safety devices protect against heat, flame and pressure.

3. Precise temperature, time and detection control follow the standard.

4. Method-specific design delivers repeatable, traceable results.

5. Clear display or software shows values and test stage.

FAQ

What are the main applications of the Vapor Pressure?

The Vapor Pressure is used to test petroleum products, fuels, lubricants and related materials for specified properties. It supports refineries, oil laboratories, fuel inspection, transport and quality-control work.

Which standards and regulations apply to the Vapor Pressure?

The instrument is designed with reference to applicable ASTM, ISO and GB/T petroleum test methods and IEC 61010 electrical safety. Procedures and reference materials must follow the named method. Compliance documentation can be provided on request.

How long is the warranty period?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Will staff need special training?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

How long does delivery usually take?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Vapor Pressure be calibrated?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are consumables and spare parts easy to obtain?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Are options or configurations available?

Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.

Is installation and commissioning included?

The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.

What should be avoided when using the Vapor Pressure?

Do not use flammable samples near ignition sources, exceed temperature limits or reuse contaminated reference material. Ventilate and follow fuel-handling safety rules.
