• Ready to use pH buffer solutions with color coding, accuracy +/- 0,01 pH at 20°C. Traceable to NIST, packed in unique designed, practical twin-neck dosing bottles!
• Unique and innovative design of the “twin neck” dosing bottles offers multiple advantages:
• No need for a separate measuring container during calibration.
• No waste of buffer since exact and correct quantity of buffer is dispensed into the calibrating chamber at all times.
• Ideally suited for field work and easy to carry.

Operation is simple, fast and easy;

• Open safety lock of the integrated calibration chamber.
• Fill calibration chamber from buffer reservoir by pressing the bottle gently.
• Calibrate pH electrode then discard used buffer solution.
• Bottle is now ready for the following use.
