The 

HI76483

 Clark‑Type Polarographic probe has a thin, 12 mm (0.47”) design that allows for convenient 

measurement in narrow vessels such as test tubes, wine bottles, and Biological Oxygen Demand (BOD) bottles.

Screw‑on caps with pretensioned membranes provide quick maintenance.

7.  GETTING STARTED

7.1.  ATTACHING THE HOLDER
Attaching the electrode holder base plate 

• Take the 

HI764060

 holder from the box.

• Identify the metal base plate (4) with the integrated pivot pin (5) and the screw (2).

• The plate may be attached to either side of the meter, left (L) or right (R).

• Place the meter face down on a clean, dry surface. 

• Align the hole on the base plate (3) over the rubber foot (6R or 6L).  

The pivot pin (5) should be facing downward.

• Use a screwdriver (1) to tighten the screw (2) and attach the base plate to the meter.

• Position the meter with the display facing up.

• Slide the holder (7) over the pivot pin (5). A “slide in” motion is required to lock the arm into position.

• For increased arm rigidity, tighten the metal knobs on both sides of the holder.
