WebAug 30, 2013 · ORP electrodes were first studied at Harvard University in 1936. These studies showed a strong correlation of ORP and bacterial activity. These tests were confirmed by studies on drinking water and swimming pools in other areas of the world. In 1971 ORP (700 mV) was adopted by the World Health Organization (WHO) as a standard … WebActive chlorine electrons increase the ORP level of the water, thus neutralizing contaminants. For chlorinated pools and spas, a safe ORP reading is usually between 650 …

ORP stands for oxidation reduction potential, and it is the oxidising capacity of your pool’s water. ORP refers to the ability of your pool’s water to oxidise active contaminants. Essentially, it is a measurement of the capacity of your pool’s water to perform sanitation. While monitoring the free chlorine level is how … See more A pool’s oxidation reduction potential is measured in millivolts or mV. The ideal voltage level for your pool ranges from 650-750mV, with many sources suggesting that 700-720mV is the most adequate range for … See more ORP is measured using an electrochemical test, similar to electrical meters for pH or TDS. These tests emit electrical pulses between probes and measure the changes in these electrical … See more The oxidation reduction potential of your pool can seem like a complicated term, but it simply refers to the overall ability of your pool’s chemicals to perform sanitation. By … See more WebApr 27, 2024 · Starting last fall (2013), The ORP would drift upward during the day after the chlorine feed had stopped. It would reach its peak about midday and then drift down.
