  • Food Sterilization System Monitors Temperature and Humidity
    CAS DataLoggers provided the temperature and humidity monitoring solution for a. decontamination facility using Ethylene Oxide (EtO) preconditioning rooms which needed to be continually monitored and alarmed to ensure safety. The facility needed a data logging system which was intuitive and easy
  • Environmental Chambers for Solar Panel Testing (.pdf)

  • Pressure Transducer Usage for Environmental Chamber Pressure Measurement for Test and Measurement Calibration Labs
    Calibration labs often require very specific knowledge of local environmental conditions. Environmental chambers present the ability to control a room's precise pressure, temperature, humidity and photo-stability or light levels. Standard electronic controls for most environmental chambers mean

  • Complying with ICH Guidelines Involving Temperature and Relative Humidity
    , a relative humidity gradient of +1% to +6% could be expected. § Add the above to the previously indicated control cycle (±2%) and the net total uncertainty, at any location a test is being performed could be anywhere from +4% to +9% or more. To obtain the true required conditions, a chamber
  • Criteria for Obtaining Specified Humidity and Temperature Conditions
