Operating instructions
Redox measurement stick ORP-01
Item no. 1763393
Intended use
This product is designed to be used in combination with suitable electrodes to measure the
redox potential (ORP) of water and aqueous solutions. Typical applications include drinking wa-
ter, waste water, surface water, swimming pools, fish farms and process chemistry. The redox
potential indicates how oxidative or reductive the measured probe is in relation to the standard
hydrogen electrode. It is measured and displayed in mV. The redox potential is often used in
swimming pools to measure the disinfecting effect of chlorinated water. The redox value is also
an important parameter for fishkeepers, as fish can only live within a certain redox range. In
addition, it plays an important role in drinking water treatment, water monitoring and in industry
and laboratories. The device is powered by two CR2032 lithium batteries.
For safety and approval purposes, do not rebuild and/or modify this product. Using the product
for purposes other than those described above may damage the product. In addition, improper
use can cause hazards such as a short circuit or fire. Read the instructions carefully and store
them in a safe place. Only make this product available to third parties together with its operating
instructions.
