Detailed introduction:

DWS-508A laboratory sodium meter


   DWS-508A is the most powerful most convenient sodium meter on the market. Equipped with laboratory ppb level electrode reference electrode. The performance of the static measurement in the beaker is greatly improved compared to the traditional sodium meter, as long as the electrode is used during use, satisfactory results can be obtained. It can be widely used in continuous monitoring of sodium ions in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food liquid.


● Chinese LCD display, Chinese menu, Chinese memo

● Microcomputer: High-performance CPU chip, high-precision AD conversion technology SMT chip technology are used to complete multi-parameter measurement, compensation, instrument self-test, high accuracy good repeatability

● High sensitivity: 0.2ppb (8pNa) can be detected in a static water sample for a long stable time with a very stable reading
