How to Use
Press key to power on the WS100 or WS200 meter, connect F501-S fluoride ion electrode (pay attention
to inserting direction), the meter automatically switches to fluoride ion concentration measurement mode.
Hold to change fluoride ion concentration unit from mg/l, ppm to pX. Release the button after selection.
Activate the electrode by soaking it in the 19.00 mg/L calibration solution for 1 hour. For regular usage, soak
10 to 20 minutes to activate it. When the reading is fully stabilized ( stays on screen), the electrode
activation is finished. Then you can start calibration and measurement. (Please note that the reading during
activation is random).
After test, rinse off the electrode with distilled water or deionized water. Shake off excess water, and store dry
with the cap on.
