Selection guidance
VIKING-PH100 is chosen for routine pH and ORP work where a simple keypad meter and printer output are enough. COLO.Science helps you choose the electrode and consumables.
Configuration checklist
- Resolution: 0.01 pH for routine work, 0.001 pH for research and pharma.
- Documentation: GLP memory, USB and printer output.
- Samples: viscous, low-conductivity or hot samples may need a special electrode.

Selection, commissioning and service support
Choosing a laboratory instrument is easier when the application is clear from the start. Tell us what kind of samples you measure, how many per day, which range and accuracy you need and which standards or internal procedures you follow. Based on that, our team recommends a suitable configuration together with the accessories and consumables that make sense for routine work, so you do not pay for options you will never use.
After delivery we stay available for practical questions: first start-up, calibration routine, daily care, storage and typical operator mistakes that shorten the life of sensors and wearing parts. If results begin to drift or the device reports an error, describe the symptoms and we will suggest what to check first before any repair is considered.
Spare parts, replacement sensors and calibration materials can be ordered later through the same contact. For a quotation or technical advice, use the request button on this page and add a short description of your application.
