PS-3003 Water-Soluble Acid Tester for Transformer Oil Testing

What Is the PS-3003 Designed to Test?

The supplied product documentation identifies GB/T 7598-2008 as the design reference. This standard concerns the determination of water-soluble acid in transformer oils in service. The instrument specifies a pH measurement range of 3.6–7.0.

Before choosing equipment, confirm that water-soluble acid determination is the test required by your laboratory or customer. A pH-based result should not be presented as an oil acid-number result in mg KOH/g. Keep the test name, method, and reporting units together when preparing specifications or reviewing results.

Automated Functions for Routine Laboratory Work

Three-Cup Sample Arrangement

The PS-3003 documentation states that one to three samples can be measured at one time. This configuration gives laboratories an option for organizing several samples within a testing run. Actual daily throughput should be assessed using the complete workflow, including sample preparation and cleaning.

Programmed Testing Functions

Listed functions include automatic heating, constant-temperature control, oscillation, sampling, testing, cleaning, and printing. The instrument also provides direct-test and standard-test program options. Operators should select the appropriate program according to the required procedure rather than assuming the options are interchangeable.

Display and Communication

A large LCD and microprocessor control provide the operator interface. A USB interface is available for communication with a computer. Buyers with specific data-transfer requirements should confirm the supplied software, file formats, and computer compatibility before ordering.

Results and Cleaning

The documentation lists storage for 100 sets of data and automatic preservation of test results during a power interruption. It also describes a selectable pipeline-cleaning function. These features should be considered alongside the laboratory’s requirements for sample identification, record retention, and cleaning procedures.

Technical Specifications

Specifications are based on the supplied PS-3003 product documentation. The standard reference is not a claim of third-party certification.

What Should Buyers Confirm Before Ordering?

Start with the required test method, sample type, and expected daily sample quantity. Then check that the stated measurement range and operating conditions match your laboratory’s needs.

• Confirm the supplied accessories and any required consumables.
• Discuss sample preparation and cleaning requirements.
• Clarify the operation of the available test programs.
• Confirm USB communication and reporting requirements.
• Request the documentation needed for installation, verification, and routine operation.

The provided specification sheet does not state a heating setpoint or complete sample preparation procedure. Operators should use the full operating instructions for these details rather than deriving them from the ambient temperature range or constant-temperature precision.

Frequently Asked Questions

How many samples can the PS-3003 measure?

The supplied documentation specifies one to three samples at one time using its integrated three-cup design.

Is the display increment the same as measurement accuracy?

No. The minimum display increment is 0.1 pH, while the stated measurement error is within ±0.1 pH. These are separate specifications even though their numerical values are similar.

Does 5–45 °C describe the test temperature?

No. It is the stated ambient operating temperature range. The constant-temperature precision is listed separately as ±2 °C. Neither value establishes the test heating setpoint.

Can the instrument communicate with a computer?

Yes. The documentation specifies a USB communication interface. Confirm the accompanying software and supported data workflow for your intended use.
