The pH Buffer Solution – TDS Water i.d. allows for more accurate calibrations, thanks to the fact that they come in individual single-use sachets.
As these are single-use sachets, there is no effect of contamination of the standard solution from other calibration solutions in a bottle.
Water i.d. pH buffer solutions allow calibration of pH probes, pH digital pencils and salt digital pencils via TDS.
It is suitable for any pH probe-electrode, as well as for digital pH meters such as the FT11 pH digital measuring pen.
The TDS standard solution allows to calibrate digital salt meters via TDS such as the FT36 TDS digital measuring pen.
In all cases they come in 20 ml sachets (box of 5 units) and can be purchased in the pH4, pH7 and pH10 options, or in the 6.44 tds salt solution.
Individual sachets of calibration solutions allow you to always have a calibration standard in perfect condition. Other solutions, such as bottles, end up giving incorrect results because they are often buffer solutions contaminated either by water or oxygen when opened.
The only way to ensure perfect calibration is to use a pattern envelope in perfect condition.
These individual sachets, moreover, do not expire, and remain in perfect condition for years of use.
Ensure perfect measurement of your pH dosing system or salt sensor with individual sachets of calibration solutions from water id.
