HANNA HI 7021 240mV ORP Solution, 230ml
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.
