Recomendaciones de productos relacionados
Electrode aging is typically indicated by:
Reduced slope during calibration
Increased stabilization time
Noticeable offset drift
Unstable readings in buffer solutions
When slope falls significantly below theoretical values (approximately 59 mV per pH at 25°C), electrode replacement should be considered to maintain ±0.01 pH accuracy.
mV drift may result from:
Reference junction contamination
Fluctuaciones de temperatura
Electrode dehydration
Electrical interference or grounding issues
Routine cleaning, proper storage in electrode solution, and stable temperature conditions help minimize drift and maintain measurement stability.
Temperature influences both:
The electrode slope (Nernst response).
The actual chemical equilibrium of the solution.
Without temperature correction, readings can deviate significantly, especially in high-temperature environments.
Monitoring temperature alongside pH ensures more reliable interpretation of analytical data.
For industrial environments:
Perform calibration before critical measurements.
Use at least two-point calibration for improved linearity.
Verify calibration daily in high-precision laboratory settings.
Always use fresh buffer solutions.
Consistent calibration ensures traceability and long-term measurement integrity.
Best practices include:
Rinse with distilled water after each measurement.
Store in appropriate electrode storage solution.
Avoid dry storage.
Periodically clean the junction according to application conditions.
Preventive maintenance significantly extends electrode lifespan and preserves measurement accuracy.
Yes.
The -1999 to 1999 mV measurement range supports ORP testing when paired with a compatible ORP electrode.
This expands the instrument’s functionality for oxidation-reduction potential monitoring in water treatment and chemical processes.
