Ti-40 Laboratory Instrument Automatic Potential Titrator
Functions
The titration modes include pre-titration, preset end point titration, mode titration, blank titration and manual titration. Different electrodes can be matched with the meter to perform different titrations including acid and alkali titration, oxidation-reduction titration, precipitation titration, complexometric titration and non-aqueous titration. The above titrations are generated into special titration modes such as pre-titration, preset end point titration, blank titration or manual titration. The meter can be communicated with the software. Titration curve can be displayed on the computer to increase the additional value of the meter.

Maintenance
Ø Keep the sockets of the meter clean and dry. Keep them away from acidity, alkaline, salt solution and also keep them damp-proof to ensure insulation and high input impedance performance of the meter.
Ø When the meter is not used, insert Q9 short circuit plug into the socket of measuring electrode to prevent if from dust and steam.
Ø When the meter is used in the place with higher humidity, dry the plug of the electrode with clean gauze first.
Ø Often clean the whole burette with distilled water, especially the titrant which produces sediment or crystal (eg: AgNO3), clean the burette in time after it is used.
Ø When using perchloric acid Acetic acid as the titrant, keep the ambient temperature higher than 16℃. Otherwise it will produce crystal, and damage the valve.
