About This Product

■Palm-sized checker HC series

The Checker HC series is a digital spectrophotometer that bridges the gap between simple reagent kits and expensive digital measuring instruments. Its special feature is that it has a digital display, is palm-sized, and is inexpensive. In addition to tap water, pools/baths, building management, etc., it is also used to check that chlorine is as low as possible in industrial wastewater. For measurements, we use the DPD reagent specified by the official method.
