Orion Pure Water™ pH Test Kit
Increases Measurement Accuracy
Reduces Electrode Drift
Eliminates Contamination of Sample
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. This kit contains special low ionic strength buffers for calibration and an additive called pHisaTM 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 ROSSTM 81-02(H250-3,4,4SC) pH electrode is recommended.
Orion Pure Water pH Test Kit includes four 475mL bottles Pure Water pH buffer A pH 6.97, two 475mL bottles Pure Water pH buffer B pH 4.10, two 50mL bottles pHisa Adjustor, one 1mL syringe, instruction card and Application Procedure No. 501 "pH Measurement Low Ionic Strength Solutions."
pHisa Adjustor Solution Bulk Pack includes five 2oz bottles, pHisa Pure Water, Ionic Strength Adjustor, one syringe dispenser.
