Introduction
HI97749 Hexavalent Chromium/Chromate/Dichromate [LR] Portable Photometer is an instrument used to measure chromium (Cr) content in water. Chromium is a toxic heavy metal, and excessive intake can be harmful to the human body. It is present in wastewater from many industrial processes and therefore can have severe impacts on water quality and the environment. It is usually used in the fields of industrial wastewater treatment, environmental monitoring and water quality control to ensure that the concentration of hexavalent chromium in the water does not exceed the legal limit and protect the environment and human health.
HI97749 Hexavalent Chromium/Chromate/Dichromate [LR] Portable Photometer complies with IP67 waterproof standard, adopts innovative optical system design, has good accuracy, repeatability and time required to make measurements, CAL CheckTM function allows the use NIST traceable standards perform performance verification and calibration of the instrument, multiple measurement methods, built-in reaction timer ensures consistent results between sample measurements and users, Good Laboratory Practice (GLP) displays the date and time of the last user calibration, Battery status indicator and auto-off settings.
