KWS-790 Digital pH Sensor – Supports both APP and PC configuration

Introduction

Digital pH sensor is a new generation of intelligent water quality monitoring digital sensor developed by our company.The data can be viewed, debugged and maintained through mobile APP or computer. It has several advantages, such as simple maintenance, high stability, excellent repeatability and multi-function. It can accurately measure pH value and temperature value in solution. It is widely used in the system of waste water treatment, purified water, circulating water and boiler water,as well as the pH test in the fields of electronics, aquaculture, food, printing and dyeing, electroplating, pharmacy, fermentation, chemical industry, etc, and it has a strong function in the environmental monitoring of surface water and pollution discharge and the remote system application.

Features 

• This product is digital pHsensor, which can directly output RS485 signal and 4~20mA signal.
• The product has high accuracy, high stability and strong anti-interference ability.
• Automatic temperature compensation function.
• Without controller, it can directly connect computer, PLC and other equipment with RS485/4-20ma signal interface for data acquisition and maintenance.It is convenient for users to integrate sensors into the industrial control environment such as upper computer system and IoT.
• Use mobile APP to collect, debug and maintain the sensor data through wired (OTG line and 485 to USB module) or wireless network (such as WIFI and GPRS).
• The sensor can be set with RS485 communication for its slave address, baud rate, online calibration, factory reset, 4-20mA output corresponding range, proportional coefficient, incremental compensation and other settings.
