ROTRONIC – HUMIDITY MEASUREMENT IN THE PHARMACEUTICAL INDUSTRY

The pharmaceutical industry is one of the largest users of humidity measurement equipment. Most drugs are sensitive to variations in humidity and moisture levels, so these need to be considered and controlled using measurement instruments, probes and sensors for the final products to be consistent in quality and performance.

Humidity Measurement Applications

Humidity instruments are used to both control (transmitters) and monitor (transmitters or data loggers) these conditions during “accelerated conditions” drug testing.

Production machines, driers, tableters, and coaters are all sensitive to humidity – quality control requires machine monitoring, area monitoring and final product Equilibrium Relative Humidity (ERH) measurement.

Clean room environments are humidity critical – environmental monitoring system (EMS) and measurement is validated to conform with regulatory requirements.
