The AutoREID apparatus from AD systems is a modern automated Reid Vapor pressure instrument in full compliance with ASTM D323-B and similar standards. This specification test method covers procedure for the determination of vapor pressure of gasoline， volatile crude oil， and other volatile petroleum products. The Reid method is particularly suitable for determination of vapor pressure of crude oil for transportation， storage and general handling purpose. The instrument directly measures the Reid vapor pressure without correlation or calculation.

Modern ergonomic design， high level of test automation， convenience in operation makes the AutoREID considerable alternative to mini-methods for precise vapor pressure measurement.

Compact instrument with two measurement positions allows performing two simultaneous measurements independently. Special additional position in the bath is dedicated for air chamber conditioning increasing the test productivity. The test pressure vessels with fast coupling assure fast and easy operation. The AutoREID design allows testing viscous sticky samples or samples containing mechanical sediments without a risk of the instrument damage. All parts of test pressure vessel are easy to disassemble and clean. Vigorous mechanical agitation of pressure vessels accelerates pressure stabilization even on “difficult” samples like crude oil.

Operation

The sample prepared in accordance with test method requirements is filled in liquid chamber which is coupled in a second with air chamber by means of specially designed quick coupling connector. The assembled pressure vessel is completely sealed. The operator enter test identification information by a few keystrokes， place the pressure vessel in water bath precisely maintained at 37，8°C (100°F) and connect the pressure link by fast connector. Plug and go operation. The test starts automatically. The pressure vessel is agitated by reverse rotation and pressure curve is displayed in real time on the large graphic screen.

Quality and Safety

During the test progress the software monitors for leaks and prevent the operator in case of pressure drop. To assure high quality of results and safety of operation the watchdog system permanently monitors the bath temperature stability， bath liquid level， overpressure or overheating.

Transparent bath cover helps to the operator visual inspection of the pressure vessels under the test.

Instrument calibration is easy to perform on-site via dedicated menu. Pressure transducers can be checked against a reference manometer at any time. The special T-connector for each measurement position is built-in for this purpose. The bath temperature can be checked by the reference thermometer. The bath cover has special opening for this purpose.

All information related to the instrument calibration is memorized to ensure a perfect traceability. The instrument calibrations are date/time tagged. The calibration interval can be managed in the software.

Test documenting

All details related to each test result are memorized. Complete test report including sample ID， operator name， date/time， RVP value， pressure curve is displayed on the screen and saved into built-in database. It can be printed， transferred on a USB memory stick and/or send to a LIMS when the AutoREID is connected to a LAN.

Multi-criteria search function facilitates retrieval of test report in the database. The software is able to calculate and report average RVP value of two parallel measurements of the same sample.
