- 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.
