What is the difference between pH meter service calibration and end-user calibration?

Calibration of measurement electronics is performed by trained service engineers using specialized tools such as multimeters, temperature resistors, and conductivity resistors.

In contrast, the end-user calibrates the measurement system using predefined buffers and sensors.

Why is pH meter service calibration important, and how is it performed?

Calibration of measurement electronics ensures the meter's documented performance, supporting reliable analyses and compliance with regulations and internal requirements. This involves conducting meter input tests and is performed by globally renowned measurement experts who will help ensure excellence in measuring pH, conductivity, ORP, ion concentration, and dissolved oxygen. 

How frequently should pH meter service calibration be performed?

pH calibration of measurement electronics is recommended to be performed annually or biannually, depending on users’ specific Standard Operating Procedures (SOPs).

What is professional installation for pH meters?

pH professional installation is part of IPac or EQPac services. It involves qualified personnel calibrating your pH meter to ensure it meets operational specifications and is suitable for your specific workplace requirements.

Why is it important to have a pH meter professionally installed?

Professional installation ensures the pH meter is correctly calibrated and functioning, providing accurate measurements. It also includes audit-proof documentation for regulatory compliance, helping to reduce the risk of non-conformance during audits or inspections.

What is the warranty period for the pH meter?

The warranty period is a one-year guarantee that the pH meter will meet specific quality standards and function correctly during the first year of ownership. 

What is included in pH preventive maintenance?

pH preventive maintenance involves visual checks and cleaning, firmware and instrument settings, functional checks, and documentation to prevent expensive downtime and repairs.
