of Chinese Stone Machinery
Feature
1. Test items; Pesticide residues, formaldehyde, sulfur dioxide, sodium bicarbonate, methanol, nitrate, nitrite, hydrogen peroxide, organic phosphorus Protein, potassium sorbate, borax, molybdenum, lead, chromium, cadmium, mercury, arsenic and other toxic and harmful substances.
2. 5-inch LCD capacitive touch screen; Human computer interaction is simple and convenient;
3. Number of channels: 10 channels, which not only ensures high test efficiency, but also ensures the accuracy and reliability of test results;
4. Instrument operation simulation: single machine, online.
5. The instrument has its own intelligent Chinese input function, which is selected by users.
6. The built-in clock can display the date (month, month, day) and week in real time, which is convenient for the operator to control the time.
7. Query function, which can be used to query items, dates and numbers by single condition or by combination of multiple conditions; Read the test data directly.
8. Built in thermal micro printer, which can print test report according to test item, date or number at any time.
9. The instrument has the calibration function. The consistency calibration between channels is completed before leaving the factory. The absorbance resolution of the instrument is 0.001.
10. Sample information: it must include sample number, sample name, test results, judgment results and other information;The instrument has an information prompt box for real-time operation steps and error prompt.
