LU-D160 Online Fluoride Ion Sensor
(RS-485/ModbusRTU)
It uses a solid membrane ion-selective electrode, which is used to test free fluoride ions in water. It is equipped with temperature compensation to ensure that the test is fast, simple and economical. This manual introduces the technical parameters, communication protocol, usage and maintenance of the fluoride ion sensor in detail.
Product use
All types of water treatment (rivers/lakes/drinking water sources/groundwater/marine water), aquaculture, environmental monitoring, CIP and related industries.
Features
● With automatic temperature compensation.
● Output standard Rs485 (Modbus/RTU protocol) digital signal.
● Signal output: RS-485 bus, Modbus/RTU protocol, conveniently connected to third-party equipment such as PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen.
● For the fluoride ion probe, the internal reference liquid seeps out from the microporous salt bridge extremely slowly under a pressure of at least 100KPa (1Bar). Such a reference system is very stable and has a longer electrode life than ordinary industrial electrodes.
● IP68 Protection rating.
● Easy to install: 3/4 inch NPT thread (pipe thread) for easy submersible installation or installation in pipes and tanks.
