Related Product Recommendations
How does Automatic Temperature Compensation (ATC) improve measurement accuracy?
pH measurement is temperature dependent because electrode slope varies with temperature according to the Nernst equation.
The integrated ATC function continuously adjusts the slope calculation based on measured temperature, ensuring accurate pH values across 0–100°C compensation range.
Without proper compensation, measurement deviation can increase significantly in high-temperature environments.
When should manual temperature compensation be used instead of ATC?
Manual temperature compensation is recommended when:
Using non-standard electrodes without integrated temperature sensors
Measuring samples where temperature stabilization is delayed
Conducting calibration under controlled laboratory conditions
Manual input allows controlled correction when automatic sensing is not preferred.
How frequently should calibration be performed in industrial applications?
Calibration frequency depends on process criticality:
Daily calibration for laboratory or compliance-sensitive testing
Weekly calibration for routine industrial water monitoring
Before critical audits or validation measurements
The 1–3 point calibration system with automatic USA/NIST buffer recognition ensures traceable and standardized calibration procedures.
Can this meter reliably measure extreme pH values such as below 0 or above 14?
Yes.
With an extended measurement range of -2.00 to 20.00 pH, the instrument supports extreme acidity and alkalinity testing. However:
Proper electrode selection is critical
Regular calibration is essential at extreme ranges
Electrode chemical compatibility must be verified
Performance at extreme pH depends primarily on electrode condition and correct calibration.
How is slope and offset information used for electrode diagnostics?
The instrument displays real-time slope and offset values during calibration.
Abnormal slope values may indicate electrode aging
Excessive offset may suggest contamination or reference junction issues
Monitoring these parameters allows preventive maintenance and ensures long-term measurement reliability.
How can measurement data be exported and documented?
The meter includes a USB communication interface for PC data transfer.
Stored data (up to 100 records) can be exported for:
Laboratory documentation
Compliance reporting
Process trend analysis
Quality control traceability
This supports structured data management in regulated industrial environments.
