What is preventive maintenance for pH instruments?

Preventive maintenance is a routine service plan that helps ensure your pH instrument operates accurately and efficiently. It involves calibration checks, cleaning, and replacing parts before they fail.

Why is preventive maintenance important for pH instruments?

Regular maintenance minimizes errors, maximizes instrument lifespans, and guarantees reliable data. This leads to consistent product quality and efficient processes.

What does a typical pH Meter preventive maintenance service include?

This can vary, but it often includes:

General inspections: Inspect the power adapter for contamination, cracks, and firm seating in the power socket, display, and keypads; examine the electrode arm for contamination, cracks, and discoloration; check the sensor condition.

Instrument setting: Checking instruments’ start-up functions, date and time, and firmware version

Operational testing: We will perform interface tests on the display, keypads, R232, USB, and stirring parts, as well as test sensor inputs with 1-2 certified tools.

Cleaning: Cleaning of connector sockets, electrode arms, and accessories

For which METTLER TOLEDO pH instruments are preventive maintenance services available?

You can order preventive maintenance services for all our Seven line meters, including SevenExcellence, SevenDirect, Seven2Go, Seven2Go Pro, SevenGo, and SevenGo Pro.

Can I perform pH Meter preventive maintenance on my own?

Users can undertake preventive maintenance activities on their own for some procedures. However, some procedures require specialized equipment or training. Consult your instrument manual and consider contacting a qualified service provider for comprehensive maintenance.

What happens if I don't perform pH meter preventive maintenance?

Unmaintained instruments can drift, leading to inaccurate measurements. This can affect product quality and process efficiency and potentially lead to non-compliant data.
