EXO pH/ORP Sensor

Users can choose between a pH sensor or a combination pH/ORP sensor to measure these parameters. pH describes the acid and base characteristics of water. A pH of 7.0 is neutral; values below 7 are acidic; values above 7 are alkaline. ORP designates the oxidising-reducing potential of a water sample and is useful for water which contains a high concentration of redox-active species, such as the salts of many metals and strong oxidising (chlorine) and reducing (sulfite ion) agents. However, ORP is a non-specific measurement—the measured potential is reflective of a combination of the effects of all the dissolved species in the medium. Users should be careful not to over interpret ORP data unless specific information about the site is known.

EXO probe with replaceable head that houses electrolyte reservoir that can be easily replaced at minimal cost to the customer. Cost of ownership is equal to existing sensors after 2 years, and cheaper in the third year of operation.

Unguarded Probes cleaned automatically in EXO2 Sondes with wiper.

Longer maintenance interval and improved response time due to preamp design. Operational amplifier in probe head that electrically isolates the high impedence signal in the probe head from the low impedence interconnect.

The tip should only be removed when being replaced with a new probe head.
