I. Features

1Android system with a 7-inch LCD touch screenhumanized Chinese operating interface, with intuitive and simple readings.
2Main control chipARM Cortex-A7, RK3288 / 4-core processor, main frequency 1.88 GHz, faster running speed and stronger stability.
3Fully sealed titration cell bottleavoids reagent contact with personnel and eliminates the influence of ambient humidity on detection; the instrument automatically controls the detection process and stirring, completing a measurement in about 60 s, directly displaying the result without frequent manual operation.
4Built-in operation videousers can watch and learn the operating method directly.
5Multiple sample typesthe instrument can test a variety of samples with cyclic detection, "load and test".
6Free editing of sample informationincluding sample name, sample number, testing unit, testing personnel, contact information, inspected unit, etc.
7Setting of test informationsuch as electrolysis current, electrolysis voltage, trace moisture content, measurement time, percentage content, injection volume, sample density, gross weight and tare weight.
8Selectable moisture detection methodvolumetric method or gravimetric method according to actual needs.
9Built-in thermal printerdirectly prints test results, with flexible setting of the printing content (QR code, sample number, testing unit, testing personnel, contact phone, inspected unit, test date, etc.).
10QR code viewingsample test results can be viewed by scanning a QR code.
11Historical record retrievaltest data can be retrieved by setting the test date, sample number, testing unit, testing personnel, sample name, inspected unit and other information.
12Standard USB interfacedriver-free installation; test-result storage capacity of more than 200,000 records, and can generate Excel tables for copying.
13Wi-Fi communication moduledata can be uploaded to a cloud platform for data query, browsing, analysis and statistics on a computer.
14Targeted remote updateupgrade and maintenance without returning to the factory, saving time and labor costs and avoiding the potential risk of equipment damage caused by logistics and transportation.
