INSTRUMENT DESCRIPTION

1) Titrant bottle
2) Liquid Crystal Display (LCD)
3) Keypad
4) Electrode holder
5) Peristaltic pump tube

• Add the content of one powder packet of

HI 84100-54

Stabilizer into the beaker.

• Place the probe holder on the top of the beaker and

secure it by turning clockwise.

• Immerse the ORP electrode approximately 2 cm

(0.8”) into the sample to be tested while paying
attention to not touch the stir bar.

• Insert the dosing tip in the appropriate holder place

and pay attention to not be immersed into solution.

• Press the START STOP button to start the titration.

The display will show “titr” during titration, along

with stirrer and pump tags blinking on the LCD.

• At the end of the titration, the Sulphur Dioxide

concentration is displayed in ppm (mg/L).

Note:

If the equivalence point is not reached or it is not
recognized because of the noisy solution, an error
message will be displayed.
