The 3556 is an economical combination electrode ideal for general industrial processes. It is well suited for testing pool water chlorination, ozone treatment (aquariums, water disinfection).
The electrode provides a fast, stable response and is ideal for prolonged ORP readings. The sealed, high polymer gel-filled design requires virtually no maintenance as there is no need to refill the reference chamber.
The outer tube is made of strong PPS plastic and is threaded (3/4" NPT pipe thread) for ease of installation.
The electrode comes with a 6 meter cable terminated by a BNC connector and a bottle of electrode solution.
