Product Description
Product Overview
This electrochemical nitrate nitrogen sensor utilizes membrane potential technology to precisely measure ion activity in aqueous solutions. The sensor generates a membrane potential proportional to target ion concentration when contacting the solution, functioning as a half-cell that requires pairing with a reference electrode for complete electrochemical measurement.
Key Features
- Digital sensor with RS-485 output supporting MODBUS protocol
- Reagent-free operation eliminates chemical waste and reduces costs
- Ion-selective method ensures rapid response and signal stability
- POM housing withstands temperatures from 0°C to 50°C
- High-quality four-core shielded cable for accurate signal transmission

Applications
River water monitoring, lake analysis, drinking water quality assessment, environmental monitoring systems, and various aqueous solution measurements.
Pre-Measurement Preparation
- Remove protective cap from electrode tip (avoid touching sensitive area)
- Shake electrode downward to eliminate internal air bubbles
- Activate new or long-unused electrodes in 1 ppm standard solution for 24 hours
- Rinse with deionized water and blot dry with non-woven cloth
- Immerse electrode tip in deionized water for 5 minutes with stirring before testing
Calibration Procedure
- Connect electrode to meter and pour 100 mL deionized water into 150 mL beaker
- Set meter to mV mode and immerse dried electrode in deionized water
- Add 1 mL of 1000 ppm standard solution, stir, and record stable reading (E₁)
- Add 10 mL of same standard solution, stir, and record stable reading (E₂)
- Calculate slope at 25°C as E₂ - E₁ and compare with specifications
Storage Guidelines
Short-term Storage
Preserve electrode in deionized water or low-concentration standard solution (1 ppm). No reactivation required before reuse.
Long-term Storage
Rinse with deionized water, gently wipe membrane with non-woven cloth, dry thoroughly, and store in original packaging. Reactivate in 1 mg/L standard solution, deionized water, or low-concentration solution for over 2 hours before reuse.
