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 separatemeasuring 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 resorvoir by pressing the
bottle gently.
Calibrate pH electrode then discard used buffer solution.
Bottle is now ready for the following use.
Other types of pH buffers can be selected from chemical
section.
