Our company has purchased 200 pH electrodes in bulk from BROADLEY-JAMES company in the United States There are 100 E-1312-ECI-M10ST electrodes and 100 C1105B-32B-A10FF electrodes These two pH electrodes are not only used for measuring the pH value of general wastewater What is even more valuable is its industrial process pH measurement, high pollution pH measurement, acid oxidizing water pH measurement, etching solution pH measurement, and developing solution pH measurement These harsh environments generally prohibit the use of pH electrodes However, E-1312-ECI-M10ST and C1105B-32B-A10FF can be used normally for about a year in these harsh environmental conditions A well deserved high-quality imported pH electrode Even the Mette PH electrode 405-60-SC is far inferior Having BROADLEY-JAMES electrodes Solved the problem of inaccurate detection and frequent issues with pH instruments Welcome customers to choose E-1312-ECI-M10ST electrode and C1105B-32B-A10FF electrode Price and everything else are negotiable!
