GEC-PAT940 Multimethods Auto titrator

   

GEC-PAT940 Multimethods auto titrator
ASTM D664 - D974-D2896 -D3227 - D4739

The GEC - PAT940 titrator is used for TAN total acid number titrator , TBN Total base number , Mercaptan Sulphur , Analysis of petroleum products , lubricants and transformer oils . The titration system comply to several ASTM , IP , ISO methods such as ASTM D664 TAN , D2896 TBN , D4739 TBN  on new and used lubricants ; and D3227 Mercaptan sulfur in gasolines , Kerosene, aviation fues and distillate fuels. All these methods predefined in one instrument easy to use

INCREASE Versatility  - SAVE  time - LOWER training level .

Burette system

Interchangeable burette assembly with intelligent volume recognition system. Simply remove the retaining screw, slide out the burette assembly and replace with different volume or titrant burette. Easy to follow screen prompts.

Titration vessel

Complete with vortex mixing for vigorous and homogeneous stirring of viscous samples. Chemically inert glass stirrer paddle. The vortex mixer is located next to the electrode so that the whole assembly can be swung away from the titration unit for easy rinsing and cleaning.

Electrode system

A range of specially manufactured color coded electrodes designed for optimum performance and excellent results and automatic recognition technology.
