Teledyne S02312 SP3X FC Free Chlorine Sensor, Low Range 0.5-20ppm

Overview

The Teledyne S02312 is a genuine SP3X FC free chlorine sensor built on Teledyne Analytical Instruments’ SP3X Smart Sensor platform, configured for low-range measurement from 0.5 to 20ppm with a PVC sensor body, flanged mounting configuration, and a 4ft integral cable terminating at the transmitter connection. The SP3 and SP3X Smart Sensor family covers a wide range of liquid measurement parameters, including pH, ORP, conductivity, dissolved oxygen, and free and total chlorine, using an interchangeable amperometric sensing electrode design that shares a common mechanical and electrical platform across the product line.

Backed by manufacturer datasheet documentation, Seven Star LLC supplies the Teledyne S02312 free chlorine sensor to municipal water treatment plants, desalination facilities, and industrial process water systems across Muscat, Sohar, and Salalah, supporting continuous disinfection monitoring programs that protect public health and process water quality throughout the region.

Operating Principle

The Teledyne S02312 measures free chlorine concentration using an amperometric, membrane-covered polarographic sensing method. A polarizing voltage is applied across the sensor’s working and counter electrodes, and free chlorine diffusing through the selective membrane generates a current proportional to its concentration in the sample water. Because the measurement is diffusion-limited by the membrane rather than dependent on sample flow turbulence, the SP3X platform delivers stable, repeatable readings across the 0.5–20ppm low measurement range specified for this sensor variant.

The sensor communicates digitally with compatible SP3X-ready transmitters such as the Teledyne LXT-380, which automatically recognizes the connected sensor type and configures its menus and calibration routines accordingly, reducing setup time and the potential for configuration errors. This digital smart-sensor architecture also supports on-sensor storage of calibration history and electrode life data, giving operators visibility into remaining sensor service life without needing to reference separate paper logs.

Across the broader SP3X free and total chlorine electrode family, the sensing element is built around a gold measuring cathode and a silver/silver chloride reference anode held behind a selective PTFE membrane, with a typical T90 response time on the order of two minutes once the membrane has equilibrated to a new sample condition. Because amperometric output current is temperature-dependent, the compatible transmitter applies automatic temperature compensation – typically on the order of several percent per degree Celsius for chlorine measurement – using the integral temperature element to hold the displayed reading stable as process water temperature drifts through the day. Supported calibration workflows include automatic two-point calibration against buffer or standard solutions, single-point standardization against a grab sample analyzed by DPD or another referee method, and manual entry of laboratory results, giving plant chemists flexibility in how they maintain traceability to their regulatory chlorine residual monitoring program.

Engineering Design of the Teledyne S02312

The Teledyne S02312 is constructed with a chemically resistant PVC body suited to continuous immersion in chlorinated water and wastewater streams, with a flanged mounting configuration that allows secure installation into flow cells, sample chambers, or in-line tees without additional adapter hardware. The 4ft integral cable provides a sealed, factory-terminated connection between the sensor and its transmitter, eliminating field-wiring splices that can introduce moisture ingress or signal noise over time.

Routine maintenance follows the SP3X platform’s standard membrane and electrolyte replacement procedure: the sensor is removed from its mounting, the membrane cap is unscrewed, the electrode surface is inspected and cleaned, fresh electrolyte and a new membrane cap are installed, and the sensor is recalibrated against a known chlorine standard before being returned to service. This modular maintenance approach keeps ongoing operating costs low compared to sensors requiring full electrode replacement at each service interval. Electrolyte and membrane service intervals are concentration-dependent: sensors operating in the lower part of their range typically need a refill on an annual cycle, while continuous duty at the higher end of the 0.5–20ppm band can call for membrane and electrolyte renewal as often as every six months to keep the diffusion-limited response within specification.
