ORP electrode / pH / titanium / laboratory

The 385/385+ pH/ORP Insertion and Retractable Sensors each feature chemically course Tefzel® product bodies complete with titanium tubes to provide overall optimal resistance. This device is also fully-sealed for maximum sensor leakage protection, and sports a long life, thanks to its three-junction reference electrode. It contains an integrated pre-amplifier for noise-free long-range high-impedance pH signal transmissions, and has a weather-proof junction box to help it withstand almost any environment it is placed into.
