Includes pH 4 and 7 reference solutions and the TA titrant (0.133N NaOH). Refill package se below!
Replenishes the pH/TA reagents provided with the SC-200 and SC-300.
Refill package
Due to regulation of transport from USA to Europe, we as importer ad the titration liquid in Sweden.
We use liquid with high accuracy that are commercially avaliable.
For the pH referens we use 4,00 and not 4,01 as in USA. This makes no practical difference in calibration.
Please note that for calculation of TA you have to use this new calculation.
The reason is that we ship the NaOH as 0,1N and in USA they use 0,13N.
(V * 0,1 * 75 )/S= the result of TA (g/L tartaric)
TA = V * 2 * 0,75
Nedan finns säkerhetsdatablad för respektive lösning:
>> pH 4
>> pH 7
>> NaOH 0,1N
