Oil Quality Tester

Product Overview:

Main performance characteristics:

THY-23AOil Quality TesterThe quality of oil has a significant impact on industrial equipment. In order to avoid deviations in oil quality, it is necessary to actively monitor the oil and determine the degree of contamination of the lubricating oil on site to determine whether to replace it.

Oil Quality TesterDeveloped using microcontroller technology, this instrument consists of sensing circuits, computer circuits, display circuits, interface circuits, and a built-in AC/DC power supply system. There are many special functions and advantages in circuit design, structural configuration, and component selection, which are manifested in the following aspects:

Further improving the testing accuracy and reliability of the instrument, it can not only measure various lubricating oils such as engine oil and gear oil, but also hydraulic oils with high sensitivity requirements;

The power supply is dual-use for both AC and DC, making it convenient to use;

During operation, simply follow the instructions in the testing window to operate according to the standard. After inspection, the oil quality will be automatically classified into three levels: scrap, usable, and good;

Easy to operate. Zero adjustment free, with only one sensor, users only need to add standard solution and test solution to each sensor separately to obtain measurement results.

Good measurement repeatability, consistent results from multiple tests.

Applicable fields:

THY-23A is a testing tool for enterprises to protect equipment, save energy, strengthen lubrication management, and achieve quality oil replacement by checking whether newly purchased and in use lubricating oil is qualified. Currently widely used in fields such as aerospace, oil fields, ports, transportation, mining, electricity, metallurgy, chemical engineering, and construction machinery. After years of development and verification, a product with high measurement accuracy, good repeatability, and wide measurement range has been produced to meet the needs of the consumer group.

preparation:

1. Place the instrument on a horizontal workbench and open the box

2. Turn on the 'power' switch

Threshold setting

Threshold setting

During the first test, threshold setting is required. Measuring the same type of oil does not require threshold setting in the future and can be done directly.

2. Soak the oil chamber in petroleum ether with a boiling range of 60-90 ℃, and then wipe it clean with a dry cotton ball.

3. First, select the oil type, and then use a sampling dropper to take 3-5 drops of new oil. When the oil level in the oil chamber is closed, press the "Lower Limit Calibration" button, and this value is the lower limit of new oil. After completion, drip into the oil chamber soaked in petroleum ether, wipe clean with a dry cotton ball, and drip in dirty oil. Press the 'Upper Limit Calibration' button, and this value is the upper limit of dirty oil. After both the upper and lower limits are available, press the [OK] key. The software automatically records it. This value is the dielectric constant value of the oil, with a range of 0-6.6. It can also be manually set within this range. For example, I set the lower limit value to 2.0 and the upper limit value to 5.0. When testing below or equal to 2.0, the test result will show: good, indicating good oil quality and can continue to be used; When the test is above 2.0 but below 5.0, the test result will show: usable. It means that the tested oil can be scrapped or continue to be used; When tested above 5.0, the test result will display: scrapped, indicating that the oil should be changed.

Oil measurement:

Oil measurement

After setting the threshold, the software will record the settings. Note that the same batch of oil does not need to be set again. We can measure it directly in the future.

2. Oil measurement: Set the oil product name and number. Take 3-5 drops of new oil with a sampling dropper. When the oil level in the chamber is closed, press the 'Start Measurement' button and the measurement result will be displayed after a few seconds. The test results are displayed on the left side of the interface, and the results are displayed in a columnar structure on the right side. Distinguish by color: good use green, acceptable use yellow, scrap use red.

3. [Save] button, the test results are stored in the database for easy querying.

4. [Print] button: Print the test results.

5. Test completed: Wipe off the oil in the oil chamber with a dry cotton ball and drip petroleum ether into the oil chamber; Clean the oil chamber with a dry cotton ball later. Prepare for the next test.

Attention: When measuring, the oil product name must be consistent with the threshold set oil product name. For example, if the threshold is set to car oil, the oil product must be car oil during measurement. If gear oil is selected, the test result will be inaccurate.

Data management

After the test is completed, you can enter the data query interface to search for data. You can search for the test results based on the oil product name, number, and testing time. Once you find the test results, you can choose to print or delete them.

Precautions for use

1) During testing, place the instrument flat and avoid vibration to ensure testing accuracy.

2) When cleaning the oil chamber, do not hit the bottom with hard objects to avoid damaging the sensor.

3) The extraction of dirty oil should be uniform, and it is best to use a sampler for extraction.

4) Normally, acetone is not used to wipe the oil chamber.

5) After the test is completed, be sure to turn off the power switch of the host.

6) The temperature range for instrument use is -15 ℃~+55 ℃. When the ambient temperature is low, the LCD screen may freeze. When the ambient temperature is too high, the data may be severely distorted.

7) Do not use in environments with strong static electricity, strong magnetism, and relative humidity above 70 degrees Celsius to avoid interfering with the operation of detection components.

Common troubleshooting

Here is a brief list of common faults and troubleshooting methods for instruments. In case of special faults, please contact our after-sales engineers in a timely manner and do not disassemble the instrument for maintenance by yourself. If any faults cannot be solved with the help of engineers, please return to the factory for repair in a timely manner.
