The ChemScan mini FreeAm (free ammonia) and the mini MonoChlor (monochloramine) from ASA Analytics can be used individually or together to create a suite of chloramination parameters for process, distribution and booster station control. They are designed for anyone needing to ensure proper amounts of ammonia and chlorine in the chloramination process. They can detect key parameters at a few hundredths of a ppm and hold calibration and accuracy for long periods without operator attention. They provide reliable and accurate analysis of water and wastewater with minimal maintenance. 262/717-9500; www.asaanalytics.com.
