Description

Product Description

pH ORP controller manufacturer Supplier CHINA DRFN

As a manufacturer and supplier of Water Quality Analyzer sensors from China, Delfino has developed an industrial online pH ORP Controller APX1-C1Z. It has a 0/4-20mA current output and a two-wire RS485 communication interface, supports the Modbus communication protocol, and can meet the needs of customers with different output data. 2 multifunctional relays can control pH dosing, sensor cleaning and temperature control. The protection level of the online pH meter is IP66, which is waterproof and dustproof in the outdoor environment. The power supply is of wide voltage, providing DC 18~36V or AC 100~240V options, which can prevent interference caused by unstable power supply.

The features of the pH ORP controller is as following:

Large-size LCD display screen, the contrast of the screen can be adjusted
The online pH controller has a password setting function to prevent misuse
Support pH three-point calibration, ORP two-point calibration of the PH Sensor and ORP Sensor, calibration points can be set by yourself
With a RS485 digital interface, it supports standard Modbus communication protocol
There are two multi-function relays, high and low alarms can be set, and the load is 1000 ohms
The material is reinforced ABS, and the protection level of the pH controller is IP66
Provide a quick calibration menu, which is convenient for customers to quickly calibrate the controller and electrodes
