Daoyi Sensing DEC-221 water quality testing instrument

The DEC-221 is a salinity sensor based on electrodeless inductive measurement using a generator in the primary line.The loop generates an alternating magnetic field,which generates an induced current in the medium. The intensity of the induced current depends on the ions in the medium.concentration. The induced current generates another magnetic field in the secondary coil. The receiver measures the induced current in the coil,given byThis determines the salinity of the medium. At the same time,it has a built-in temperature sensor,which can automatically compensate the temperature and is suitable for online long-term monitoring.test environment.

Features:1. Digital sensor,directly outputs Rs-485 digital signal,supports MODBUS/RTU2. Built-in temperature sensor,automatic temperature compensation3. No electrodes,so no polarization reaction4. The measurement is completely electrically isolated from the medium,enabling high-precision measurement of heavy and easy-to-precipitate or solutions.Measurement,low use and maintenance costs5. The sensor has low power consumption and internal circuit anti-interference design

Application scope:Online whole-process monitoring of oceans,industrial wastewater,pharmaceuticals,biotechnology,industrial manufacturing,etc.
