High Temperature Resistant 135℃ Analog PH Electrode For Pure Water >5μS/Cm

This robust PH sensor ASP121E boasts a broad measuring range of 0 to 14 pH, making it highly versatile. It features a low-impedance cylindrical glass membrane for rapid and stable readings. The sophisticated Ag/AgCl reference system, with a double salt bridge and KCl gel, effectively and extends the sensor's lifespan, even where traditional single-junction electrodes might fail.

Engineered for Durability and Precision
The electrode is constructed from durable glass with a unique dot-shaped ceramic frit, offering superior resistance to chemical attack.

Operating Pressure & Temperature:

Standard Environments: Operates continuously from 0°C to 80°C with pressures up to 6 bar. For high-temperature applications, it can withstand up to 100°C for less than 60 minutes with pressures up to 3 bar.

Customizable High-Temp Version: Available for continuous use up to 100°C or short-term exposure up to 135°C (under 60 minutes). This model has been rigorously tested to endure more than 40 high-temperature cycles in a clean water environment.
