DWS-5088 Industrial Online Sodium Meter

●Overview

  DWS-5088 industrial sodium meter is a brand-new ppb-level measuring electrode, an automatic constant pressure constant flow liquid system, a stable efficient alkalization system, ensuring the stability accuracy of the measurement. It can be widely applied to the continuous measurement of trace sodium in mediums such as effluent, desalinated water, make-up water, condensed water, distilled water steam in power system, chemical system, pharmaceutical industry other departments.

●Features

  Chinese LCD display, Chinese menu, Chinese memo

Microcomputerization: Adopt high-performance CPU chip, high-precision AD conversion technology SMT chip technology to complete multi-parameter measurement, temperature compensation, automatic range conversion, instrument self-test, high accuracy good repeatability
