  Author:MeCan Medical–ultrasound machine manufacturers

The use of portable pesticide residue detectors allows us to quickly detect whether the drug residues of agricultural and sideline products such as food, fruits and vegetables exceed the standard, and effectively improve our diet safety. In order to make the test results more accurate and reasonable, users must use the operating program of the portable pesticide residue detector strictly. If the error operation is wrong, alarm prompt will appear.

Portable pesticide residue detector specific use steps are as follows:

1. Connect the power. The right switch on the right side of the instrument is allocated to the state of "opening", open the upper cover, and wait for the instrument self-inspection program to complete (about 5-8 seconds), and warm up by "start". At this time, the LED screen shows the current temperature that is rising. When the setting temperature TEMP (39 C) is reached, the bee tweee emits a "beep" prompt sound, the screen displays Time1, the preheating is over, and the start can start to start the count of Time1 (10 minutes).

2. Fold the quick -test card along the middle line, remove the quick -test card protective film, and insert the quick test card. At this time, the red pills are upward, and the white pills are placed on the heater. Then drop two drops of extract on the white pill.

3. Press the "START" key to start the timing. If the operation of the built -in beever will emit a continuous sound, the screen displays the word "Open" until the operator opens the upper cover to restore the normal working state Bee Narrator to stop the tweet.

4. After the count of Time1 is completed, the bee tweee emits a sound (there are prompts in 5 minutes), the screen displays "Clos", prompting the front cover to enter the count of Time2 (3 minutes). If the prompt is prompted to be closed, it has not been covered after 5 minutes. The screen display the "OFF" computer prompts to shut down, and the test strip is invalid. At this time, if you want to re -work, you must dial the switch on the right side of the portable pesticide residue detector to the state of "Guan", and then dial from the state of "Kai" to "open" to start a round of detection.

5. When the six "beeps and beeps" sound are heard, the operation is over, and the color changes are turned on to measure the color of the test strip. The test paper shows that blue is negative (non -toxic), light blue is weak and positive, and white is positive (toxic). After the detection, take the test strip up and start the next test.

6. Extract liquid: Take 5 grams of fruit and vegetables on the surface, cut into 1cm size with scissors, add 10 ml of pure water, stir with glass rods (each sample needs to be replaced once, or use pure purification washing with pure purification Three times, then use the) leaves with full contact with water. Each batch is made of 11 samples, and at the same time, a blank control of pure water. Each cut into a sample, the scissors should be washed, and the other sample is processed to avoid pollution and affect the test results.

7. The results of the pesticide quick test card are judged. Compared with the blank control card, the white pills are unchanged or slightly blue are positive results, and the non -changing blue is a strong positive result, indicating that the amount of pesticide residues is high. The light blue is weak and positive, indicating that the amount of pesticide residues is relatively low. The white pills become blue or the same as the blank control card, which is negative result.

The above is the explanation of the steps of portable pesticide residues, I hope it will be helpful to you.
