as already seen in section 7, the choice of the right measuring instrument is very important for achieving the best humidity measurement results.
Calibration times and traceability standards should also be regularly maintained. Products manufactured in cleanrooms or in laboratories, production facilities, warehouses...cover a wide range, including pharmaceuticals, semi-conductors and food products....
Humidity and temperature are often monitored, as these parameters can have serious effects on product quality and production efficiency.
Sometimes it's practical to maintain an internal calibration system. This may be the case when measuring equipment is difficult to transfer (on-site calibration), or when the quantity of calibrated equipment (or instrument stock) is high.
To set up an in-house calibration system, an appropriate department should be set up.
This department may contain a single person or an entire department with management and calibration staff.
It is preferable for the calibration laboratory to provide its services in the field.
In a laboratory, environmental effects can be minimized, and the number of factors influencing calibration is significantly reduced. Field calibration is a quick and easy way to check measuring equipment without having to remove it from the field, but it does require some knowledge to get good results.
The working standard may be another piece of equipment used to calibrate the instrument installed in the process.
These standards are calibrated in a higher-level laboratory and must be stored in suitable locations to protect them from vibration, dust and sunlight....
