New offset adjustment feature for total residual chlorine meter

摘要

Extech Instruments' new offset adjustment feature is available now in its ExStik~® total residual chlorine meter, Model CL200. Reading in ppm, it can be precisely adjusted to match the value of a known standard or to agree with previously established references. The meter monitors Total Chlorine Residual, which includes free chlorine and/or chlorine bound to nitrogenous compounds, (chlo-ramines). Direct reading of Total Chlorine from 0.01-10.00 ppm are done quickly and easily without need to store and transport a sample solution back to the lab for analysis.
