Maintenance intervals for Testomat

Regular maintenance is required to ensure the proper functioning of Testomat instruments.
The measuring chamber and its condition are of elementary importance for photometric measurement.
During regular operation, a visual inspection of the measuring chamber and the hydraulic and electrical connections is sufficient. The frequency of the inspection should take into account the area of application and the associated quality of the water to be analyzed.

The following intervals for the visual inspection and the replacement of components are recommendations and must be adapted to the operating conditions and the condition of the device if necessary.
