Rugged line of industrial pH and ORP sensors for inline, immersion & submersible, twist lock quick disconnect, valve retractable and sanitary installation types.  Available for wide range of applications from slurry/viscous solutions, sulfides, high-temperature, organic applications with various solvents, HF etching and treatment systems and many more. Custom applications inquiries are welcome. Most complete line of industrial ion selective sensors offered anywhere.  Available in inline, immersion, submersible, twist lock quick disconnect and sanitary configurations.  Complete ISE systems including sensor and transmitter are supplied complete, including a calibration scheme that is optimized for your intended application use. Validation of process for feasibility is required for each ISE measurement. Everything from low-cost 2-wire and 4-wire transmitters and controllers all the way to explosion-proof & programmable instrumentation for single, dual and triple channel pH, ORP, ion selective (ISE), conductivity and dissolved oxygen (DO) measurements.  Options include PID & TPC relay controllers, HART, Fieldbus & MODBus digital outputs as well as multiple 4-20 mA analog current loop outputs. All enclosureare NEMA 4X or higher rated.

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 contating conductivity sensors (other materials upon request). Cell constants available from 0.01 to 10.0 and anywhere in between. Rugged industrial grade galvanic dissolved oxygen (DO) sensors offer high accuracy measurement at a very low cost of commissioning as well as a low residual cost of ownership. Unique optional thick-membrane option is ideal for heavy slurry media and rugged NPT submersion sealing assembly ensures very long sensor life even with severe service conditions and handling. Convenient quick disconnect termiation option allows for simply maintenance for long cable runs and tricky installation setups. The longevity of the pH, ORP and ion selective (ISE) sensors can be significantly elongated for some applications using our waterproofing sealing options for a variety of applications. In particular, for those that will be completely submersing the sensor or for applications where the back of the sensor will be exposed to moisture or facility washdowns these waterproofing seals are a must. Inquire to the ASTI factory to determine if a waterproofing option is required for your installation type and if required the most suitbale selection. Special materials of construction are available for our waterproofing seals upon request.
     

HOT-TAP Valve Retractable Assemblies

The third generation valve retraction HOT-TAP assemblies allow for insertion and removal of the sensor without shutdown or separate isolation of the process line or tank. These HOT-TAP assemblies are available for 5X31, 5X41 & 5XX0 sensor types. Available in 316SS material of construction standard with TEFLON seals and ferrules with Viton or Kalrez O-rings ensure a secure water tight even at high temperatures (150 deg Celsius) and pressures (up to 150 psig max). Custom materials of construction and configurations are available upon request.

Please keep in mind that the links above do not represent the entirety of the ASTI industrial product line but rather the most commonly sold offerings. For example, please inquire directly to the factory for any dissolved oxygen and temperature measurement needs in addition to the pH, ORP, ion selective (ISE) and conductivity electrochemical products links detailed above. The valve retractable and submersible options are available for most industrial measurement product lines although you should inquire to the factory to confirm that it is supported for your specific requirement.
