Benchtop sodium ion analyzer for water quality testing
Model： ERUN-ST3-M6
The ERUN-ST3-M6 desktop sodium ion analyzer, manufactured and sold by Erun Environmental Protection, is an improved version of previous models that featured analog displays, knobs, switches, and non-intelligent designs. Equipped with specialized electrodes for ppb-level sodium ion measurement in laboratories, its performance in static measurements in beakers is significantly improved compared to traditional sodium meters. With proper electrode cleaning during use, satisfactory results can be easily obtained. It can be widely used for continuous monitoring of sodium ions in solutions in various industries, including thermal power, chemical and fertilizer, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

1. Color LCD touch screen with beautiful display and user-friendly interface for easy operation;
2. Can simultaneously display multiple parameters such as pH, sodium ion concentration, and temperature;
3. Calibration uses two standard solutions, and the calibration process iteratively calculates the background sodium content in the standard solutions, eliminating the influence of background sodium.
4. Optional dynamic measurement mode for more accurate measurements;
5. ARM processor technology, the instrument has automatic slope calculation and automatic temperature compensation functions.
6. High-precision pH and sodium electrodes for accurate measurements;
7. The sensor signal conditioning section adopts an isolated power supply design, significantly reducing external noise interference.
