FAQ
Q:
Why is moisture in my new pH meter?
A:
New pH meters are stored in a special solution to maintain the integrity of the
electrode and its glass membrane. This glass membrane must be kept moist
in order for the pH meter to function properly.
Q:
Why did my pH meter turn off?
A:
Your pH meter will automatically turn off after 8 minutes of inactivity.
Q:
How often should I calibrate the pH/conductivity?
A:
Your meter's accuracy depends on several factors like the environment
it's used in and how often it is used. We recommend calibrating your pH
meter once a month, after testing a series of samples, or if readings don't
appear accurate.
Q:
What is the difference between conductivity, TDS and salinity?
A:
Conductivity is a measure of a solution's ability to conduct electricity,
while TDS (total dissolved solids) and salinity are measures of a solution's
concentration of dissolved solids and salt, respectively.
Q:
What is the difference between USA and NIST in the settings?
A:
The USA and NIST settings differ in the buffer solutions used for calibration.
The USA settings use three buffer solutions with pH values of 4.00, 7.00, and
10.00 while NIST uses the pH values of 4.01, 6.86, and 9.18.
