Condiment safety detector
The condiment safety detector can quickly detect the total nitrogen, amino acid nitrogen, ammonium salt, free mineral acid, heavy metal arsenic, and lead in the edible vinegar in soy sauce; the detection instrument is integrated by the light source, colorimetric pool, and high sensitivity Photocell, microprocessor, large Chinese character LCD screen, embedded mini thermal printer, wireless transmission module and integrated chip, which can directly display the content of relevant indicators in the tested sample on the large screen LCD screen and print it out The analysis results can also be transmitted to the "Food Safety Information System" terminal database for analysis through a computer interface. The method has low cost per test, simple and fast operation, and is convenient for law enforcement personnel or production quality control personnel to use on-site and on-board.
The principle of the instrument: the relevant index components in the tested sample react specifically with the developer under certain conditions to produce products of different color depths. These products will selectively absorb different wavelengths of visible light, and the color depth is The level of absorbance is correlated with the concentration of the index component in the sample, and obey Lambert-Beer law within the appropriate concentration range. Therefore, the detected absorbance value is automatically calculated by the standard curve software built in the instrument to obtain the accurate concentration of the index component in the sample and whether the result exceeds the standard.
7-inch color Chinese LCD touch screen (size can be customized according to customers)
Adopt new instrument structure design, small size, easy to carry. No mechanical moving parts, anti-interference, anti-vibration,
Simultaneous start and single channel start two measurement modes respectively. When measuring multiple samples, the customer can choose the measurement mode according to the proficiency of the operation to eliminate the measurement error caused by the coefficient of variation between the channels to the greatest extent.
High accuracy: the imported special LED light source is used, which has good wavelength accuracy and repeatability, and comprehensively improves the accuracy of the test results.
High degree of automation: instrument automatic diagnosis system failure, wavelength calibration: automatic calibration
Long service life of the instrument: LED light source, automatic switching energy-saving design, discontinuous working mode. Service life up to 10 years
The instrument automatically stores more than 8000 measurement data. Built-in micro thermal printer, no need to change the ribbon for life, can print the test results in real time, the test report can print the name of the vegetables, inhibition rate, whether it is qualified, test date, test unit. It can reflect the authority of the test results and facilitate publicity.
Equipped with RS-232 interface, USB port wireless Wifi, Ethernet interface, etc., data processing, statistical analysis and result uploading can be performed through the computer. If the company's food safety monitoring network software is selected, networks at all levels such as provinces, cities, prefectures, and counties can be formed according to user requirements.
Number of colorimetric channels: 5, 8, 10, 15, 16, 20, 25, 30 channels (number of channels can be customized according to customer)
The basic properties of EVA material: shock resistance, heat insulation, moisture resistance, chemical corrosion resistance and other advantages, and do not absorb water. EVA rubber and plastic products are designed to be processed into various colors. Its shockproof performance is better than that of traditional packaging materials such as polystyrene (foam), and it meets environmental protection requirements, making it the choice for export products. Compared with the requirements of special product applications, it has fire-resistant (flame retardant) EVA products; due to the large difference in density, it can also have more uses.
Water resistance: closed cell structure, non-absorbent, moisture-proof, good water resistance.
Resistant to chemical corrosion such as seawater, grease, acid and alkali, antibacterial and odorless
Shock resistance: high resilience and tensile strength, strong toughness, good shock resistance and cushioning performance.
Thermal insulation: thermal insulation, thermal insulation and cold protection and low temperature performance, can be cold and exposed to the sun.
Sound insulation: closed cells, good sound insulation, effectively reduce the volume decibel.
Processability: easy to cut, punch, hot press, slit, form, glue, fit, pad and other processing.
