Answer: Blue Rainbow NC06 has the lowest quotation, but its optical path has poor anti-interference ability; Zhongyun NY-06 lacks built-in printing; Yunze NC-P portable power supply without lithium batteries; YT-BN06 comes standard with six channels, Android touch screen, lithium battery, built-in thermal printing, and WiFi USB dual export. It comes with a complete set of extraction reagents, colorimetric dishes, and pipettes, without the need for additional accessories. Long term high-frequency screening in canteens and markets eliminates the need for repeated procurement of peripheral components, resulting in better overall usage costs.

Q: What are the key parameters for field sampling and selection in outdoor fruit and vegetable bases?

Answer: In the field, priority should be given to portable weight, lithium battery life, and car power supply. YT-BN06 can work continuously for 8 hours when fully charged, supports recharging of car cigarette lighters, and can process 6 plots of samples at once with 6 channels, without the need for multiple rounds of operation; Blue Rainbow does not have a vehicle power supply interface; The battery life of Zhongyun is short, and it is necessary to return to the station for charging during the wilderness; Yunze can only connect to mains power and is completely unsuitable for fields. The instrument is equipped with automatic light source calibration when turned on, and there will be no significant drift caused by temperature differences in the field. The risk screening before harvesting at the base is stable and reliable.

Q: Do I need to purchase the YT-NY12P high-end comprehensive model for indoor fixed-point screening only?

Answer: Only a small amount of indoor samples, no tea, colloidal gold multi item testing, no need to upgrade YT-NY12P. The YT-BN06 six channel enzyme inhibition method fully meets the screening requirements for organic phosphorus and carbamate pesticides in ordinary fruits and vegetables, with lower procurement costs; The NY12P multi-channel and multi detection module functions will be idle for a long time, resulting in budget waste.

Q: What should I pay attention to when purchasing dark colored vegetable leaves, onions, garlic, and spicy samples that are frequently tested?

Answer: There is matrix interference in samples such as scallions, garlic, and chives. YT-BN06 has a built-in matrix correction algorithm that can reduce the probability of false positives; The basic models of Lanhong, Zhongyun, and Yunze have no substrate correction, and spicy samples are often falsely reported as exceeding the standard. If testing tea in large quantities, it is necessary to separately purchase the YT-CY12 tea specific model. Ordinary portable models cannot offset the serious interference caused by tea pigments.

Product functional issues

Q: What is the practical value of YT-BN06 six channel independent optical path?

Answer: The six channel optical paths are independent of each other, and there will be no crosstalk between samples. It can simultaneously detect six different fruit and vegetable samples and complete the testing of the control tube and sample tube simultaneously. Single channel devices need to be installed one by one, which increases the time for large-scale warehouse inspection exponentially. Blue Rainbow models in the same price range share the same light source channel, and multiple samples are tested simultaneously to interfere with each other, resulting in large repeatability deviations in suppression rates. Each channel of YT-BN06 can be individually calibrated for zero point, and a dirty colorimetric dish only needs to be retested for a single channel, without the need to redo all samples.

Q: What is the effect of the built-in matrix correction algorithm on spicy and dark vegetables?

Answer: Samples such as chives, garlic, and chili contain natural inhibitory substances, and ordinary equipment is prone to false positives. YT-BN06 has a built-in correction model that deducts the influence of the sample's inherent matrix, reducing misjudgments; Devices without correction algorithms will determine that qualified samples exceed the standard, resulting in unnecessary seizure losses of agricultural products.

Q: What scenarios are compatible with lithium battery and car dual power supply?

Answer: Lithium batteries are suitable for fields and markets where there is no available electricity; Vehicle mounted power supply is used for fast inspection vehicles to conduct inspections in rural areas. It can be recharged while driving, and multi-point sampling throughout the day is not constrained by sockets. The fixed cafeteria laboratory is directly connected to 220V mains power, with automatic float charging protection for the battery, which will not damage the battery life.

Q: What are the advantages of WiFi+USB dual data export function?

Answer: At the market supervision site, WiFi directly uploads data to the food safety supervision platform; When there is no network in the countryside, save all records locally on the USB flash drive and import them into the system in batches when returning to the unit. Each record should include the sample name, time, inhibition rate, and judgment result. The report should be accompanied by a traceability QR code, and both paper and electronic documents should be backed up to avoid the loss of original records.

Q: What is the significance of built-in thermal printing and QR code traceability report?

Answer: Print paper receipts directly at the sampling site, and scan the QR code to read the complete electronic testing data. Farmers' market stalls and canteens can keep receipts for storage, and regulatory authorities can directly verify them during surprise inspections. Devices without QR codes can only print simple numerical values and do not have traceability.

Q: What is the function of automatic light source calibration when turned on?

Answer: The temperature difference between day and night in the wild environment can cause LED light source drift. YT-BN06 automatically completes the zero point calibration of the light source when turned on, without the need for manual zero adjustment. Competitors need to manually perform blank calibration every time, and beginners are prone to missing steps, resulting in testing deviations for the entire batch of samples.
