Product Details
Product configuration
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.
Main features
- This product is digital PH sensor, 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.
- Two point correction is used.
