Range : -1999 mV to 1999 mV
Accuracy : +-5 mV
Resolution : 1 mV
Charging time :4h(After charging 16 hours of continuous work)
Operating Temperature : 0 – 50°C
Calibration : By mini screwdriver (included)
Calibration Method :
1,Switch at the ORP Meter , and immerse the electrode within the distilled water for few hours .
2, Immerse the electrode in 256mV calibration solution (4.01 calibration solution of quinhydrone reagent), stir the meter gently.
3, Wait till the reading is stabilized , and adjust the reading to 265mV by pressing the potentiometer with the screwdriver.
4, Rinse the electrode with distilled water .
NOTE: Keep the electrode immersed in Potassium Chloride Solution for few hours for each 15days can take care of the accurace of the ORP Meter.
(Calibration solution isn’t provided with packing , because liquid and powder are condisidered to be dangerous , please buy it on your local store )
