GDYQ-901SC2 Food Nitrite Rapid Analyzer Introduction: The GDYQ-901SC2 rapid nitrite analyzer is suitable for quantitative determination of nitrite in meat products, canned meat, vegetables, pickled vegetables, fresh meat, fresh fish, edible salt, bottled beverages, various dried fruits and herbs, and suspected substances of nitrite poisoning. characteristic: 1. Instrument composition: The instrument consists of LED light source, colorimetric cell, microprocessor, etc 2. Optical path system: The instrument light source and detector adopt an all solid state structure, with no movable parts, and high accuracy and precision; Adopting energy-saving design with automatic light source switching, the service life of the light source is over 100000 hours. Compared with traditional spectral systems, the structure is simple, and the seismic and moisture resistance performance is strong 3. Display mode: Adopting a 4.7-inch large LCD screen with Chinese display. Directly display the concentration of the measured substance and show the absorbance of the current measurement 4. Built in curve: With a built-in working curve, there is no need to prepare standard solutions. Only zero point calibration with matching reagents is required to achieve rapid quantitative determination of samples 5. Measurement method: Equipped with a dedicated 19mm color comparison bottle with engraved lines, it is convenient for sampling. At the same time, this color comparison bottle can be used as both a reaction bottle and a measurement bottle, without the need for transfer, greatly facilitating customer use and reducing operational errors. After the detection is completed, it has a buzzing prompt sound 6. Specialized reagent kit: Equipped with a specialized reagent kit, greatly reducing the preparation time of reagents, easy to operate, and convenient to use 7. Lower computer software: The single machine has functions such as data processing, result statistics, and printing selection 8. Upper computer software: Equipped with dedicated workstation software, it can input information such as sample name, tested item, testing institution, and testing personnel, and can export data in EXCEL format. Test reports can be directly written and printed through an external printing system. The detection data can be directly uploaded to the online supervision platform, making it easier for regulatory authorities to establish inspection databases in a timely manner 9. Data interface: USB and RS232 interfaces for external devices, supporting data management and instrument control 10. Power supply mode: AC/DC dual-use, the instrument is equipped with a built-in lithium battery to meet emergency and on-site testing needs, and also has a self diagnostic function for battery level, automatically indicating low battery level Technical parameters: 1. Light source: Ultra high brightness light-emitting diode 2. Wavelength: 538 nm 3. Determination lower limit: 2.0 mg/kg (sampling mass 1 gram) 0.1 mg/kg (sampling mass of 20 grams) 4. Measurement range: 0.0~200.0 mg/kg (sampling mass 1 gram) 0.0~10.0 mg/kg (sample mass of 20 grams) 5. Measurement accuracy: ± 2% 6. Power supply: AC power supply (220V ± 22V, 50Hz ± 1Hz); Rechargeable battery (7.4 V, 900 mAh) 7. Size: 310x225x125 mm 8. Weight: less than 1.7 kg
