Aqua3700D Desulfurization & Denitrification Glass pH Electrode
Summary:
The Aqua3700D pH electrode features a pressure-resistant cylindrical bulb, an SRG-specific synthetic gel intermediate electrolyte, and a PTFE salt bridge, enabling it to deliver excellent measurement performance and long service life even under desulfurization and denitrification operating conditions characterized by high sulfide ion concentrations, abundant suspended particulates, and elevated heavy-metal ion levels. Moreover, its superior resistance to high temperature and high pressure makes it the preferred choice of specialized electrodes for the desulfurization and denitrification industry.

Detailed introduction
Product Features
- Tetrafluoroborate salt bridge, resistant to clogging, resulting in a lower liquid junction potential. SRG’s specially formulated synthetic gel electrolyte is highly resistant to sulfide poisoning. Dual liquid-junction design ensures long service life and IP68-rated waterproof performance.
- The sensitive film is robust and resistant to mechanical impact.
- Stable measurement, long service life
