What should be noted when maintaining a rapid pesticide residue detector? The pesticide residue detector is based on the principle of enzymatic reaction kinetics. If the tested sample contains organophosphorus or carbamate pesticides, it will inhibit the activity of cholinesterase, affecting the reaction speed of the colorimetric system. The amount of pesticide residue in the tested sample (inhibition rate) can be measured by measuring the rate of change of absorbance of the colorimetric system over time. Shenzhen Fenxi Instrument Manufacturing Co., Ltd. specializes in producing pesticide residue detectors and has obtained a national certificate (new type: 201620531841. X appearance: 201630158215.6); The pesticide residue detector is based on the enzyme inhibition rate method in the agricultural standard method (NY/T 448-2001) and the national standard (GB/T5009.199-2003), strictly following the provisions of the "Standard for Rapid Detection of Organophosphorus and Carbamate Pesticide Residues in Vegetables" for the rapid determination of organophosphorus and carbamate pesticide residues in vegetables. Accurate and rapid detection of organophosphate and carbamate pesticide residues in vegetables, fruits, grains, tea, and soil. It can be widely used in food safety testing and monitoring places such as vegetable testing centers at all levels of government, agricultural markets, supermarkets, environmental protection agencies, vegetable planting bases, restaurants, vehicles, and laboratories to determine pesticide residues in fruits and vegetables.

The rapid pesticide residue detector can be divided into two types: desktop and portable. Made outstanding contributions to human health. If users use the pesticide residue rapid detection instrument improperly, it may cause damage to the instrument and shorten its service life. By using the correct usage and maintenance methods, the instrument's service life can be extended, which not only saves costs for users but also facilitates their use.

1、 Precautions for maintenance of portable pesticide residue rapid detection instrument

1. When using the rapid pesticide residue detector for the first time, ensure that the lithium battery is fully charged. When installing the lithium battery, the user should pay attention to the polarity of the battery plug.

2. If the indicator of the pesticide residue rapid detection instrument does not light up, it indicates that the current battery level is too low. To ensure that the instrument is in the power on state, users should charge it in a timely manner, otherwise the instrument will automatically shut down. 3. In order to extend the service life of the instrument, if the instrument is idle for a long time, the rechargeable lithium battery should be removed and stored properly in a dry place; Or timely recharge.

4. The environment for placing instruments should be kept dry, dust-free, and vibration free.

5. The internal channel of the pesticide residue rapid detection instrument should be kept clean and free of dust. If there is any dirt, it should be wiped clean.

6. The instrument should be turned off when not in use. After the instrument is turned off, if the power adapter supplies power, the power indicator will light up. If it flashes, it indicates that the lithium battery is charging.

7. Before using the instrument, it is necessary to carefully read the instrument manual and follow the operating steps in the manual. If there are any abnormal phenomena with the instrument, the seller should be notified or sent to a repair point for maintenance. Users are not allowed to disassemble and repair on their own, otherwise it will affect the seller's provision of services according to the instrument maintenance terms.

2、 Precautions for daily maintenance of desktop pesticide residue rapid detector

1. The rapid detection instrument for pesticide residues must be kept dry in the colorimetric cell during use, and water should not seep into the colorimetric cell, otherwise it will affect the measurement results and the service life of the instrument. In severe cases, it may even damage the instrument.

2. After use, the instrument should be wiped clean with a dry soft cotton cloth in a timely manner. If not used for a long time, the instrument should be stored in a dry place in the instrument box to ensure good accuracy, reliability, and a long service life.

3. Attention: It is strictly prohibited to wipe the instrument with strong acid or alkali, and it is strictly prohibited to wash the instrument with water. After introducing the precautions to be taken when maintaining a rapid pesticide residue detector, I believe you have gained some understanding.
