2. UNSTABLE READINGS / SLOW RESPONSE
A soiled membrane or dry reference junction can cause unstable/slow response of sensors. Rinse the sensor with plenty of water
and recondition the sensor in 100 ppm standard solution for at least one hour.
Temperature changes, pH variation of solutions, or ambient electrical noise may also contribute to the issue. The source should be
identified and corrected.

D*
This method using the nitrate ion selective electrode is one of EPA approved methods for measuring nitrate in drinking water and
wastewater, listed in USA Code of Federal Regulations Title 40 Part 136 and Part 141. The PT6 is compatible to follow this
method. Consult with your regulator for reporting purposes.
