FAQ
Q: How can I get the quotation?
A: You can send the inquiry on Alibaba or the below contact information, you will get the reply at once.
Q: What is the minimum measurement range of this sensor?
A: This sensor offers extremely high accuracy for low-range applications, such as pure water. With an electrode constant of 0.1 cm⁻¹, the minimum measurement range is 0.200 µS/cm. Resolution: Up to 0.01 µS/cm at low ranges. Ideal for ultrapure water, distilled water, or precision water quality monitoring at laboratory levels.
Q:Which electrode constants does this sensor support?
A:To adapt to different application scenarios, the following three standard electrode constants are provided for customers to choose from:
K=0.1: For monitoring pure and ultrapure water.
K=1.0: For municipal tap water, industrial cooling water, and general water treatment.
K=10.0: For high-conductivity environments such as high-concentration industrial wastewater, seawater desalination, or chemical treatment.
Q: What’s the common power supply and signal output?
A: 5 ~ 24V DC ；RS485
Q: How corrosion resistant and durable is it?
A: The housing and electrodes are both made of 304 stainless steel, providing excellent corrosion resistance.
Protection rating: IP68.
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 trnasmission module.
Q: Do you have the matched software?
A:Yes, we can supply the matahced software and it is totally free , you can check the data in realtime and download the data from the software, but it need use our data collector and host.
