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
resorvoir by pressing the bottle gently.
Calibrate pH electrode then discard
used buffer solution. Bottle is now ready
for the following use.
Ready to use pH buffer solutions at
20°C.
Measured with a combination glass
electrode after multiple point calibration
with reference materials.
It is certified traceable to the following
National Institute of Standards and
Technology (USA).
