Characteristics:
Zero potential point: 7 ± 0.5 pH
Conversion coefficient: > 95%
Installation size: 3/4NPT
Pressure: 1 ~ 4 Bar at 25 ℃
Temperature: 0 ~ 60℃ for general cables
Intro to The MEJ-PH5013A PTFE pH sensor for corrosive medium
Mejor will systematically review the advantages of the sensor in terms of material properties, structural design, measurement performance, and application adaptation, highlighting its performance in corrosive environments.
Ultra strong chemical resistance:
Made of polytetrafluoroethylene (PTFE) material, it can resist strong corrosive media such as concentrated sulfuric acid, concentrated nitric acid, aqua regia, etc., and is not afraid of organic solvent erosion, ensuring long-term stable operation.
Long life maintenance free:
Special diaphragm and dual chamber electrolyte design effectively isolate pollution, reduce electrolyte consumption, decrease replacement frequency, and extend maintenance cycle by more than 50%.
High precision and stable measurement:
Based on the potential analysis method and optimized electrode structure, the measurement accuracy can reach ± 0.01 pH, and the data can still remain accurate and reliable in complex corrosive environments.
Quick response:
The porous PTFE membrane has high ion permeability, with a response time of less than 30 seconds, and can capture pH changes in real time to meet dynamic monitoring needs.
Wide applicability:
Temperature resistance range -20 ℃~150 ℃, suitable for different working temperature conditions; Support online continuous monitoring and laboratory offline measurement, suitable for various industrial scenarios.
Strong anti-interference ability:
PTFE has excellent insulation performance, effectively shields electromagnetic interference, ensures stable transmission of measurement signals, and avoids data fluctuations.
Environmental safety:
The material is non-toxic, does not release harmful substances, meets environmental standards, and is suitable for detecting corrosive media in industries with high safety requirements such as food and pharmaceuticals.
