Shen ChangHong Just after the Spring Festival in 2010, the R & D Department of the company launched a series of desktop testers. The main products are: do-3b precision dissolved oxygen tester, con-2b precision conductivity tester, tm-1b conventional water quality five parameter tester and so on.
Phs-4d and phs-5e precision acidimeters are upgraded versions of phs-3d and phs-4e respectively, which have changed the original LED display and adopted large screen liquid crystal display, making the measurement data more clear and intuitive, and the performance is as reliable and stable as ever.
Phs-5e has added data storage function, which can view measurement records at any time, and can store 99 pH values.
