ZEUS™ Industrial Grade pH sensors are designed and built with Extremely Rugged Construction to handle the Toughest Severe Service Process Inline, Immersion or Submersible Installations.

Unique solid-state non-porous conductive polymer reference technology and thick-wall break-resistant parabolic pH glass sensing elements along with the specially designed construction of ZEUS™ pH sensors ensure the longest service lifetime possible in aggressive media such as abrasive slurries and solutions with high particulate content.

ZEUS™ pH Sensors support High Temperatures & High Pressures for Process Solutions with Dissolved Ammonia, Chorine, and Sulfide gases and are compatible with most Organic Solvents.

ZEUS™ pH Sensors are available in three ANALOG CONFIGURATIONS to interface most all existing OEM transmitters:

  1. UNIVERSAL (Item # 1202) configuration is without integral preamplifiers for instruments that can accept this type of pH sensor and installations that do not require longer than 25 feet of cable (cable length for UNIVERSAL sensors cannot be extended)
  2. WITH CONVENTIONAL PREAMPLIFIER (Item # 1203) configuration is for instruments that can accept this type of pH sensor with 20 feet cable standard & NEMA 6P snap connector; Max 330 feet total cable length with snap extensions

Complete specification sheets linked above for item # 1202, 1203, 1204 or 1205 configurations can also be obtained from the QR code on the respective ZEUS™ sensor label via the QR scanner app on your mobile device

While the ZEUS™ pH Sensors are only available in the configurations as detailed above, all other IOTRON™ series pH sensors can be custom built-to-order specific to your exact application requirements. Please review our pH sensor overview webpage to select the customizable product line that is most suitable for your need if you prefer this option. All other IOTRON™ series pH sensors are not in stock since they are built-to-order to suit specific requirements. Lead times are normally relatively nominal since most all necessary components are well stocked for most combinations and the availability is only limited by actual manufacturing time, processing of the order and time in the production queue.
