水中氟離子選擇電極 IntelliCAL™ Fluoride ISE Analysis Package
ISEF121是測量飲用水,廢水和一般水質應用中氟離子濃度的理想選擇。IntelliCAL™ ISEF121 is a digital, combination fluoride ion selective electrode (ISE) with a non-refillable, single junction reference and built-in temperature sensor.

The IntelliCAL ISEF121 probe is available with a 1 or 3 meter cable and is intended for laboratory use.

The ISEF121 is ideal for measuring fluoride concentrations in drinking water, wastewater, and general water quality applications.

The ISEF121’s solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE.

The IntelliCAL™ Fluoride ISE Analysis Package contains the IntelliCAL™ ISEF121 Fluoride ISE, 100 pack of fluoride ISA powder pillows (258999), 500 mL of 0.5 mg/L fluoride standard solution (40505), 500 mL of 1.0 mg/L fluoride standard solution (29149), and 500 mL of 2.0 mg/L fluoride standard solution (40520).
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
