Field to Lab to Process Testing for Chlorine and Turbidity in Randleman, NC

July 25 @ 8:00 am - 4:00 pm

Cost: $180 per person
This workshop is designed to teach proper analytical techniques for systems using chlorine for disinfection. Analytical technologies covered in the workshop will be colorimetry analysis for chlorine using the Pocket Colorimeter II, DR900 colorimeter, and DR1900 spectrophotometer for field and lab testing; and CL17 and CLT10 for process testing. Technology covered for turbidity will be 2100Q, TL23, and TU5200 for lab analysis, and 1720E and TU5400 for process testing.

Test parameters analyzed will be free chlorine, total chlorine, and turbidity. An ultra-low range chlorine procedure will be demonstrated with a DR1900 and a pour-thru cell. The course objectives will be met by presenting test theory, incorporating practical applications of analytical techniques with “hands-on” experience with test systems. Students are required to analyze water samples of known and unknown values. Attendees have the option to bring their own instrument to class.
