ORP Electrodes are provided with a platinum sensor for most applications, while a gold sensor is required for measurement of cyanide or highly oxidative environments.
The most advanced feature in some models is a flat tip which virtually eliminates dirt deposits significantly reducing maintenance. Hanna flat tip electrodes are ideal for continuous in-line monitoring and for solutions containing aggressive chemicals. PVDF, glass and PEI bodies all offer a high level of mechanical and temperature resistance. Hanna also has over 300 combination pH and ORP electrodes.
