TEA 4000

The TEA 4000 – the best solution for trace analysis in your lab, factory or even mobile.

Description

The TEA 4000 is a polarographic analyzer with a very small footprint that provides maximum performance at low purchase and operating costs.
It offers full experiment control and data evaluation via PC with the supplied measurement software. The optional field module enables mobile use for maximum flexibility.

Some of the areas in which the TEA 4000 can be used include the following:

Environmental analysis: water and soil
Tribo-analysis in the engine industry.
Monitoring of wastewater and process water.
Quality assurance in
- Food production
- Metal, electronics or chemical industry
Purity analysis e.g. in electroplating & metallurgy
… and other applications

Some of the outstanding features of the TEA 4000 at a glance:

Minimized space requirements thanks to compact design
Simple sample preparation
Simultaneous detection of several elements
Use without inert gases possible
Low operating costs
Very low detection limits

The versatility of the TEA 4000 is clearly visible in the range and variety of applications. Here is a list of some possible applications of the TEA 4000:
