NB-16C Pesticide residue tester
Work principle:
Test item:
Pesticide residues in fruits and vegetables
Feature:
1, The test results can be qualitatively and quantitatively. The qualitative display results are the inhibition rate, and the quantitative results are mg/kg.
2, 7-inch large LCD backlight display screen, Android system is simple to operate, easy to upgrade.
3, Built-in GPS module (built-in, no external antenna required), real-time positioning of longitude latitude, accuracy within 5 meters.
4, Built-in thermal high-speed printer (no need to replace the ribbon) can print barcode, vegetable name, inhibition rate, pesticide content (quantitative), whether it is qualified, the date of detection, the detection unit (can be modified on the host), latitude and longitude , temperature and humidity, radiation and other parameters.
5, Can set more than ≥105 vegetable and fruit names on the instrument host
6, The light source self-test is performed when the instrument is turned on, and there is no need to manually adjust the light block.
7, Can store ≥ 180,000 pieces of detection information, automatically save data function, the stored data is not lost after power off, with a complete query statistics function.
8, Can set the reaction time and the upper limit of the qualified standard on the host
9, Simultaneously measure 16 samples, which can be measured simultaneously or separately. The host has a built-in micro-printer, which can report the pesticide residue data to the agricultural supervision information system.
10, Upload the stored data to the computer using GPRS or WIFI wireless mode. If equipped with a mobile phone card, you can send a text message to the mobile phone.
11, User management: In order to prevent misuse, the host built-in customer management system, the user can set the user name and password.
12, Data query: It can be checked according to the test date and test number, and the stored measurement data is deleted. Data can be deleted, deleted, printed, forward and reverse sorted, sorted by project name, filtered by date, and so on.
13, With voice guidance, broadcast function, can switch between Chinese and English.
14, The host standard test environment parameters, air temperature, humidity, dew point, etc., environmental parameters can be accessed at the same time can also be connected to the host separately, all measurement data display on the same interface (optional).
