Fluoride (F⁻) Ion Selective Electrode

Fluoride (F⁻) Ion Selective Electrode

Intellical™ ISEF121 is a digital, combination, Fluoride ion selective electrode (ISE) with a with a non-refillable gel reference with a single junction porous PTFE annular ring, and built-in temperature sensor. The electrode measures fluoride concentration in water samples. The laboratory version of this ISE is shockproff with its Epoxy plastic body.The Intellical ISEF121 probe is available with a 1 or 3 meter cable and is intended for laboratory use. The ISEF181’s solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE. The ISEF121 is ideal for measuring fluoride concentrations in wastewater, drinking water and general water quality applications.

 

Description

Details

  • Requires virtually no maintenance – The solid-state sensor design allows for DRY storage of the ISE without a shelf life. Also, the probe does not require the electrolyte to be refilled or membrane replacement.
  • Fast, stable, and accurate results – Intellical digital probes lock on the result when the measurement is stable, removing the guesswork in having a moving number. Additionally, the probe’s large annular reference junction provides maximum surface area between sample and reference electrolyte for fast measurement stability.
  • Ultimate traceability in measurement history – Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number.
  • Can be moved between meters without the need to re-calibrate or re-enter measurement settings – Ideal for a multi-user environment with multiple HQD series Laboratory and Portable meters

Comes with: Intellical ISEF121 combination Fluoride ISE, 1 m cable (ISEF12101), Test certificate, and Basic User Manual.
