YIERYI Range:0~1999mg/LmV Digital Handheld ORP Tester ORP Meter ORP-B Water Hydroponics

    Oxidation and reduction potential, referred to as ORP or Eh. ORP as a comprehensive indicator of the environmental conditions of the medium (including soil, natural water, energy water, medium, etc.) has been used for a long time, which characterizes the relative degree of oxidative or reductive properties of the medium.

    ORP test pen is mainly used to measure the negative potential energy water machine, hydrogen-rich water, nano-energy cup, anion energy cup, calcium ion cup, nano-energy π cup, and other water negative potential detection, accurate know how much anion in water.

Specifications:

• Remove the protective cap. Do not be alarmed if white crystals appear around the cap.
• This is normal with ORP electrodes and they dissolve when rinsed with water.
• Turn the meter on sliding the switch on the top.
• Immerse into solution up to the max immersion level.
• Stir gently and wait until the display stabilizes.
• After use, switch off ORP meter,, use the water clean the electrode and replace the protective cap.
• Do not use distilled or deionized water for storage purposes.
• Large fluctuations in readings could be due to lack of calibration, dry electrode or rundown batteries.
• Attention :during 2-3 weeks, put electrodes in 3mol/L KCL solution for 12 hours, to make sure the reading within accuracy.
