VicoMeter at the Customer Site

Upon arrival, the VicoMeter engineer first verified the accessory list with the customer's purchasing department. When their operators arrived, the engineer began installing while explaining. Because the customer had used similar instruments before, installation was quickly completed. The engineer then verified the instrument with 2 µL of deionized water in three tests—1945 µg, 1952 µg and 1936 µg—within the required 1900–2100 µg, confirming the instrument itself was sound. Two tests with the customer's oil sample followed: one by the engineer with a 1.0239 g sample giving 26 ppm, and one by the customer with a 1.1741 g sample giving 22 ppm. The customer was very satisfied with the results.

Hangzhou Electrochemical Group Co.

Hangzhou Electrochemical, founded in 1936, has undergone two relocations and three entrepreneurial phases. In 2010, under the municipal government's unified plan, the company moved entirely from Puyan to Linjiang. With support from leaders and government departments at all levels, guided by harmony, low carbon and green principles, and built to high standards with advanced clean processes and first-class electromechanical equipment, the new plant was rationally laid out to modern enterprise requirements, completed and successfully commissioned in one attempt in May 2010—achieving seamless relocation and immediate profitability in the same year.

The company values independent technological innovation as a national high-tech enterprise, a provincial innovation pilot and a key supported enterprise under the "Five Batches" program, with a provincial technology center and provincial key pilot-test base; high-tech products account for over 50% of output value.
