Product Description The NHR-FCL80 Series Free Chlorine Recorder is a high-performance online measurement instrument designed for monitoring free chlorine levels in water. Utilizing the amperometric constant voltage method, it can be configured with a flow cell to continuously measure free chlorine content in water. It is especially suitable for continuous monitoring of chlorinated water in applications such as swimming pools, drinking water, secondary water supply, and bottled water production.The NHR-FCL80 Series Free Chlorine Recorder features two analog signal outputs, two relay alarm outputs, and RS485/Ethernet communication interfaces, providing flexible options for data transmission and system monitoring. It provides powerful display capabilities, including real-time trend, historical trend recall, event log, alarm log, and file list-allowing users to clearly monitor system status. Additionally, it supports online calibration and temperature compensation, enhancing measurement accuracy and stability. The recorder is widely used in industries such as food and beverage, healthcare, water supply, secondary water supply, swimming pools, and breeding operations.
