- Longer bath life than conventional surfactant cleaners
- Reduced cleaner consumption
- Lower maintenance and overall costs

- Very low VOC values: particularly environmentally compatible
- Very good filterability: high economic efficiency
- Surfactant-free: no surfactant residues on surfaces

- Wide process window, therefore suitable for various cleaning applications in electronics
- Very high bath loading capacity, thus enabling very long bath service lives
- Based on halogen-free, organic solvents, therefore particularly environmentally friendly

There are several ways to check the condition of your cleaning chemistry.
Firstly there is the titration method using the Zestron Bath Analyser kits. These are a simple and cost-effective way to monitor bath concentration of both Alkaline and ph Neutral cleaning agents.
The Zestron Eye Mobile is a process monitoring tool which allows an operator to check the bath concentration and record the results. It can be programmed to monitor most Zestron cleaning agents.
The Zestron Eye is a dedicated process control tool which can be installed in most types of cleaning machines and allows real time monitoring of the cleaning process.
The video below gives a brief overview of the different methods for monitoring the condition of your cleaning process: https://www.youtube.com/watch?v=F9IZcBYIvVU
In addition, it is possible to evaluate the condition of your cleaning chemistry by sending bath samples to Zestron for analysis to help determine bath life. Please contact for sample bottle kits.
