Product Q&A

Q:What is the measurement principle of this sensor?

It uses the colorimetric principle where NO3-N absorbs UV light at 210 nm. The sensor calculates concentration based on light absorption as the sample flows through the slit.

Q:What is the warranty and after-sales service?

We provide warranty support and after-sales service support. Our team is available 24 hours a day for technical assistance and product training.

Q:Can the cable length be extended?

Yes, the standard cable length is 10 meters, but it can be extended up to a maximum of 100 meters.

Q:What materials is the sensor body made of?

The body is made of SUS316L for fresh water applications or Titanium alloy for ocean marine environments.

Q:What are the typical applications for this sensor?

It is widely used for continuous monitoring in sewage treatment, surface water monitoring, industrial wastewater drainage, and fishery fields.
