Q: What's the main characteristics of this PH sensor?
A: It is easy for installation and can measure the water quality online with the RS485 output,4~20mA output, 0~2V, 0~2.5V, 0~5V, 0~10V voltage output, 7/24 continuous monitoring.

Q:Could I get samples?
A:Yes, we have materials in stock to help you to get the samples as soon as we can.

Q: What’s the common power supply and signal output?
A: 5 ~ 24V DC (when the output signal is 0 ~ 2V, 0 ~2.5V, RS485)
B:12~24V DC (when the output signal is 0~5V, 0~10V, 4~20mA) (can becustomized 3.3 ~ 5V DC)

Q: How can I collect data?
A: You can use your own data logger or wireless transmission module if you have , we supply the RS485-Mudbus communication protocol.We can also supply the matched LORA/LORANWAN/GPRS/4G wireless transmission module.

Q: Do you have the matched software?
A:Yes, we can supply the matched software and it is totally free , you can check the data in real time and download the data from the software, but it need use our data collector and host.
