Many laboratories take pH measurements of "pure water" with low levels of acid, base or dissolved salts. The low conductivity and limited buffering capacity of low ionic strength pure water causes pH electrodes to drift, producing non-reproducible and inaccurate results.
Using the Orion Pure Water pH Test Kit provides fast, accurate pH results in high purity waters. Recommended for samples such as well water, rain water, distilled/deionized water, boiler feed water, and process water.
Product Detail
Increases measurement accuracy
Reduces electrode drift
Eliminates contamination of sample
This kit contains special low ionic strength buffers for calibration and an additive, called pHISA Adjustor, to increase sample ionic strength without changing its pH. Recommended for samples such as well water, rain water, distilled/deionized water, boiler feed water, and process water. For best results, a high quality pH electrode such as the ROSS Ultra® glass-body pH electrode, Cat. No. 8102BNUWP is recommended.
Orion Pure Water pH Test Kit includes:
four 475 mL bottles Pure Water pH buffer A pH 6.97 (700702)
two 475 mL bottles Pure Water pH buffer B pH 4.10 (700704)
two 50 mL bottles pHisa Adjustor (700003)
one 1 mL syringe, instruction card and Tech note 501. "pH Measurement in Low Ionic Strength Solutions"
