Product Description

 

 

HJ-PH101 is a new product independently developed by our company. It is an intelligent digital sensor. It is compact and portable, and has excellent waterproof performance. It only needs a sensor to work, saving the cost, life and traditional of the controller. The electrodes are the same, even longer.

With temperature compensation function, the temperature can also be measured while measuring the ph value

With RS485 modbus communication protocol output, using DTU connection to transmit data to the Internet, you can use your mobile phone to view data anytime, anywhere.If you don't need the Internet, you can use our company's collection software, and you can view the data when the computer is offline.

At the same time, it can also have a 4-20mA current output signal, which is connected to your PLC device.

There are three power supply options: 5V/12V/24V.

The most important thing is that we are an independent R&D and production enterprise, supporting OEM and customized products.
