Precautionary Labels

Read all labels and tags attached to the instrument. Personal injury or damage to the instrument
could occur if not observed. A symbol on the instrument is referenced in the manual with a
precautionary statement.
The TitraStir Titration Stand is an optional accessory for Hach's Digital Titrator system. It is a
single-speed magnetic stirrer with a specially designed holder for the titrator, the temperature
probe, and electrodes in applications where they are used. The titration flask is placed on a
white disc to provide better color definition when looking for an end point color change. In the
table below, pertinent electrical and physical characteristics are given.
Multiple hazards. Only qualified personnel must conduct the tasks described in this
section of the document.
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to
the current safety data sheets (MSDS/SDS) for safety products.
Figure 1 shows the assembly of the titration stand. The Digital Titrator and titrator cartridge are
not part of the TitraStir stand but are shown to demonstrate how they are installed. There is a
slot in the side of the Titrator/Electrode holder to accommodate the delivery tube. A ½-inch
wrench can be used to moderately tighten the support rod assembly in the titration stand.
Set up the TitraStir so that the power cord can be easily disconnected. A protective earth ground
is required.
The following accessory items are included with the TitraStir Stand. Please verify that all the
items are present when unpacking the shipping carton.
