The COD tester PhotoLabS6 is designed for comfortable operation and simple routine testing, and is widely used in industrial processes and wastewater analysis. The latest developed optical path system does not include moving parts, eliminates mechanical wear, and is equipped with the latest electronic circuits. When the user opens the flip cover, the instrument automatically turns on to detect the light path system. The flip cover not only provides protection, but also has a concise operation guide for easy reference. The layout of the large-sized LCD display content is reasonable, clear and concise, and it can also display operation guides during operation.

AutoSelect Automatic Selection
AutoSelect means that users do not have to worry about which testing method to use, as long as a standard reagent tube is inserted, the instrument will automatically select the corresponding testing method, and after the test is completed, the test results will be automatically displayed.

MemoChip storage chip
MemoChip makes instrument upgrades very easy. When upgrading, simply introduce MemoChip, turn on the instrument, and the PhotoLabS6 COD tester will immediately permanently store the new testing method in its instruction system, eliminating the need to replace the EPROM.
