Industrial pH, ORP, Ion Selective (ISE), Conductivity & Dissolved Oxygen (DO) Sensors

IOTRON™ Industrial pH/ORP Sensors

Rugged line of custom built-to-order analog & smart digital industrial pH, ORP & Dissolved Oxygen (D.O.) sensors for inline, immersion & submersible, twist lock quick disconnect, valve retractable and sanitary installations for wide range of applications from slurry/viscous solutions, sulfides, high-temperature, organic applications with various solvents, HF etching and treatment systems & many more. Unique features include low-profile break-resistant parabolic thick-wall pH glass elements and platinum ball ORP sensing elements. Special reference option for extreme dehydration resistant allows for intermittent wet & dry use and prolonged exposure to air without drying out. The pH, ORP & Dissolved Oxygen (D.O.) sensors with integral analog preamplifiers are available with optional rugged field ready waterproof quick disconnect Q7M snap connectors. Smart digital pH sensors & ORP sensors come standard with NEMA 6P rated quick disconnect HiQ4M snap connectors. Support for pressures up to 200 psig and temperatures up to 150 degrees Celsius.

IOTRON™ Industrial Ion Selective (ISE) Sensors

Most complete and rugged line of industrial ion selective sensors offered anywhere. Continuous inline measurement of ammonium, calcium, lithium, sodium and silver cations and fluoride, chloride, bromide, iodide, cyanide, nitrate, nitrite and perchlorate anions. Available in inline, immersion, fully submersible, twist lock quick disconnect, sanitary and HOT-TAP valve retractable installation configurations. Ion selective (ISE) measurement systems are supplied complete including sensor and transmitter calibration scheme that is optimized for the intended application use. Unique AB 6100 fluoride ion selective sensor is the only type in the industry that is suitable for low pH acid/etching solution at elevated temperatures and to undergo strong acid cleaning regimen. Validation of process for feasibility is required for each ISE measurement. Generally only an offset calibration with the ISE sensor left in continuous field service is needed to allow for good agreement with offline grab sample determinations, most typically analyzed with a portable photometer.

Industrial Conductivity Sensors

Contacting and torodial (inductive contactless) industrial conductivity sensors for use up to 205 degrees Celsius and 500 psig. Suitable for measurements from 0.55 microSiemens and up to 2,000 milliSiemens. Applications from ultrapure water to strong acids, bases and electrolytes. Materials of construction include 316SS, Monel, Titanium, Hastelloy C-276 (and other) for the electrodes and TEFLON, CPVC, KYNAR and PEEK for the insulator on contacting conductivity sensors (other materials upon request). Cell constants available from 0.01 to 20.0 and anywhere in between to suit any measurement requirements. Custom configurations and designs are available upon request for any applications that are not serviced by the existing sensors detailed on our website (MOQ may apply).

Industrial Dissolved Oxygen (DO) Sensors

AST-DO-UNIVERSAL Rugged Industrial Galvanic Dissolved Oxygen Sensors with High Stability Thick Membranes for Inline, Immersion, Submersion, Sanitary & HOT-TAP Installations. Ideal for Continuous Measurement in Tough Applications such as Processes with Abrasive Slurries, High Levels of Organic and Biological Content as well as solutions with High Turbidity & Viscosity. Available in without preamplifier configuration for use with up to 15 meters (50 feet) cable or with integral analog conventional preamplifier configurations are rated for use with up to 100 meters (330 feet) total cable length. The with integral preamplifier AST-DO-UNIVERSAL DO sensor configurations are available with optional rugged field ready quick disconnect NEMA 6P rated Q7M/Q7F snap connectors. Smart Digital MODBUS RTU dissolved oxygen sensor configurations allow for seamless hot-swap plug and play operation and include waterproof snap connectors standard with cable lengths up to 1,000 meters (3,280 feet) supported.
