HANNA HI 7091M ORP Reducing Pretreatment Solution, 230ml
HANNA HI 7091M ORP Reducing Pretreatment Solution, 230ml
For a faster response time, pretreat the ORP electrode prior to use by soaking it in pretreatment solution for 15 minutes, then rinse the electrode with water.
Use HI7091M ORP reducing pretreatment solution for Ionized/Alkaline negative (-) ORP testing.
Use HI7092M ORP oxidizing pretreatment solution for water disinfection positive (+) ORP testing.

 HANNA Instruments HI 7021 240mV ORP Calibration Solution, 230ml ORP standard solutions allow you to test the precision of ORP electrodes. For example, by immersing the electrode in HI 7020 solution, you should read within the 200 to 275 mV range (@20�C/68�F). If the reading is outside the indicated interval, clean and condition your ORP electrode in HANNA instruments pretreatment solution. Use HI 7092 for oxidizing or HI 7091 for reducing pretreatment.
