　　Introduction to Food Safety Comprehensive Analyzer

Product composition and description

This instrument adopts the standard method and performs quantitative analysis based on the principle of Lambert Beer law, using unknown concentration samples and known concentration standard substances. The expression of Lambert Beer's law is as follows: A=- logT=bc, where A represents the absorbance of the substance; T - transmittance of the substance; The absorption coefficient of a substance; B - Optical path length; C - the concentration of a substance.

The instrument consists of an LED cold light source, a colorimetric cell, a photodetector, a photoelectric sensor, a microprocessor, and a micro printer. It can directly display the content of harmful substances in the tested sample on the LCD screen and print out the analysis results. At the same time, it can be operated online with a computer through a USB interface and monitored through a monitoring network system for statistics, summary, analysis, and monitoring.

(9) Sample pre-treatment is convenient.

　　Operating Instructions for Data Collection Instruments

(1) Insert the power adapter into a 220V power outlet, and connect the DC socket of the adapter to the power interface of the instrument to power on the instrument.

(2) Press the switch on the back of the instrument to turn on the power and start the instrument. Before connecting the power, please check the sample room and do not place colorimetric dishes or other foreign objects; Close the door cover of the sample chamber.

(3) After connecting the instrument, it performs a self-test and displays the self-test interface. At this point, please note that if the instrument fails the self-test, it will automatically display a message indicating that the self-test did not pass. You can turn it off and then turn it back on. If the self check still fails, please contact the merchant; After passing the self check of the instrument, it will automatically enter the interface of the main menu for selecting detection items. 【 Note 】: After entering the detection item selection interface, it is recommended to preheat the instrument for 10 minutes to ensure that the light source is stable before starting the measurement.
