From Craft calibration and the many pitfalls to these daily handles. In each water treatment facility of a public swimming pool needs to be done: Measuring and logging water chemistry. In previous articles, we have often discussed it, but always on the edge and not focused on the activities of calibration.

Calibrate: Calibration is in the field of measurement of water parameters for the definition “Which signal of the sensor corresponds to which value.” used.

Together with the Humboldt University in Berlin, the project was continued "development of a system for ion-specific control of the nutrition of crops in cultivation in greenhouses". The cooperation project focused on the development of a system for ion-specific control of the nutrition of crops in the greenhouse cultivation. This task was divided into 3 areas: 1. Ion-selective measurement of chemical parameters present in the nutrient solution of greenhouse cultures. 2. Determination of the setpoint values for the chemical parameters as the difference between measured value and desired value-dependent growth. 3. Dosing of the individual components in the circuit.

The weight of a human being is made of about two kilograms bacteria. What role the tiny lodger, is hardly known so far.
Disinfection 01 Terms and Overview
Disinfection:
Literally: "De-infecting" = "preventing contagion". In the parlance "free of microorganisms make".
In the parlance "free of microorganisms make". The literal language is lost. According to the German Pharmacopoeia (DAB) means disinfection: enable "dead or living material in a state, that it can not infect "
Disinfection 02 Sterilisation
Sterilisation: process, be freed by the subjects of microorganisms. with sterilization, refers to sterilization and disinfection process, by the materials and articles of live microorganisms including their dormant stages (for example spores) be freed. The thus achieved state of materials and articles are called "sterile".
Disinfection 03 Time to reduce by 90%
Time to reduce by 90%: The Dezimalreduktionszeit is the time, in the 90% die of a population. Is the time required, die in the nine-tenths of the population, the population is thus reduced to a tenth, as Dezimalreduktionszeit D (D value).
Disinfection 04 KBE / CFU
KBE / CFU: Colony forming unit, colony forming unit. A colony forming unit (CFU or CFU, englisch colony forming unit, CFU) is a parameter, which plays a role in the quantification of microorganisms, namely when the viable cell count of microorganisms in a material is determined culturally.
Disinfection 05 process
disinfecting process. The history of mankind is the history of disinfection. Immediately after discovery of fire, the fire was used, boil water to. The high temperatures kill harmful organisms in the water and made the water for people available.
