MODBUS RTU Digital Universal PH ORP Transmitter Large LCD With Time History
Brief Description
pH is measured in a wide variety of process applications to ensure product quality, monitor effluent discharge, and control the addition of chemicals for the optimum chemical reaction.
DUC series PH ORP digital universal controller, is a single parameter controller, each pH ORP transmitter, will be pre-installed with a set of embedded software to adapt to different PH/ORP digital sensors. By accessing various different types of PH/ORP digital sensors, to achieve the measurement needs of different scenarios.
The protective grade of the DUC pH ORP transmitter is IP66, which can effectively isolate the pollution of the external environment and the invasion of the corrosive gas. Rich output configurations are available to meet the different detection needs of many applications.
Advantages Of pH ORP Transmitter
128 * 64 large LCD screen, Chinese and English display, rich content.
The connected sensors upload the detected data in a special encrypted communication method to ensure that the controller can collect high-precision data in a more stable manner.
The pH ORP transmitter has 2 settable SPST multi-function relays and 2 high-precision 0/4~20mA current outputs.
The Menu password can be set to facilitate hierarchical management.
A two-wire RS485 interface.
Applications Of pH ORP Transmitter
