Dual channel food heavy metal detector

1. Product Introduction:

Holder Electronics HD-LZ300 dual-channel grain heavy metal detector is suitable for the detection of heavy metals cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), mercury (Hg) and beneficial elements selenium (Se) in rice, rice, brown rice, wheat, corn, beans and other grains and their products. The instrument adopts electrochemical stripping voltammetry, combined with screen-printed electrodes and simple sample pretreatment methods, and dual channels are quickly detected simultaneously.

2. Application Field:

Dual-channel grain heavy metal detector is widely used in grain depots, grain inspection stations, food production/processing enterprises, scientific research institutes and other grain and oil products. Storage, circulation, processing links, suitable for grain purchase on-site environmental conditions detection and accurate and stable results.

3. Product features:

1. The detection limit of heavy metals in grain can reach 20ppb, with high accuracy and precision CV<10%;

2. Dual-channel simultaneous detection, single sample detection <15min, two samples simultaneous detection <20 minutes (including pre-treatment time);

3. No need for strong acid heating, one-click detection of lead and cadmium and simultaneous results;

4. The instrument has built-in instructions and operation videos, and the detection process is simple and easy to operate. Suitable for on-site detection by non-professionals;

5. The instrument is lightweight, equipped with a portable suitcase, and has a battery standby time of more than 8 hours, which is suitable for on-site rapid detection;

6. The instrument uses disposable screen-printed electrodes, which are easy to use and stable, simple and convenient, and do not require expensive consumables and accessories.

4. Performance parameters:

1. Android smart operating system, full Chinese operation interface, simple and easy to learn, no professional personnel required;

2. The instrument has a built-in database of multiple samples, and no spikes are required during the detection process, and the heavy metal content in multiple samples can be detected.

3. The system software must include sample detection, data query, help, statistical analysis, and system setting functions. The instrument can be connected to the Internet via WiFi, and the system software can be connected to the information network platform of the regulatory unit;

4. It adopts an integrated computer control, no external computer is required, built-in 1.2GHz quad-core processor, 1GB memory, which can meet the rapid calculation of large amounts of data during the detection process.

5. It adopts a 10.1-inch high-definition color touch screen (resolution 1024*800), full touch screen operation, simple software operation interface, and easy to use;

6. The detector is equipped with two-way automated micro-electrochemical mixers, which can detect the heavy metal content in two samples at the same time. The mixer can fully improve the sensitivity of the detection method, and the sensor connector can be flipped and moved to facilitate sensor insertion.

7. The instrument has its own protection function, and the user name and password can be set to prevent non-staff operation;

8. The instrument has built-in operation manual documents and operation videos, which makes it easier to use and detect, without professional training, and is suitable for on-site detection by non-professionals;

9. The instrument has built-in national standard limit standard documents, which can be opened and studied from the instrument;

10. The instrument has a data analysis function, which can screen the qualified rate of test data within a certain period and express it through a bar chart;

11. Standard WIFI and USB interfaces can realize wireless Internet access and data transmission functions; table documents can be exported for convenient statistical analysis;

12. The instrument has 8GB of physical storage and can store at least 50,000 sets of test data.

13. The instrument has a built-in thermal printer, which can print information such as the name of the test project, project type, test results, test personnel, test unit, test personnel, limit standards, etc., and can quickly print test results on site;

14. The instrument uses an external 220V, 50/60Hz AC power supply; built-in lithium battery, independent working time without external power supply> 8 hours, with external power supply power indicator, plug in the adapter without turning on the machine to display the battery charging status. Adapt to the environmental conditions of the portable acquisition site and ensure the accuracy and stability of the test results;

15. The instrument has voice prompts during operation, which is convenient for users to grasp the sample test status in time. The help interface can view limit standards, product manuals, test operation videos and other functions.

16. The instrument can detect multiple heavy metal elements at the same time, with a detection time of 5 minutes; the detection time of a single heavy metal can be as low as 30 seconds; the pre-treatment process does not require strong acid and heating digestion;

17. The instrument uses disposable screen-printed electrodes, which are disposable and easy to replace, without polishing, which improves the detection speed;

18. It can automatically diagnose system failures, manage user permissions (allocate permissions based on roles, realize hierarchical management of user permissions, thereby ensuring data security and convenient management), set the upload data platform information, and can be remotely upgraded for free online, and increase detection items according to user needs;

19. Different test kits can be used to detect cadmium (Cd), lead (Pb), arsenic (As), zinc (Zn), copper (Cu), selenium (Se), etc. in grain and other food and agricultural product samples;
