Temperature measurement can be a very important task where the accuracy and reliability of the result is vitally important. In these cases, calibration of the equipment is very important. The same is certainly true for humidity measurements using a hygrometer. Applications where this could be of utmost important include:
Castle can calibrate thermometers and hygrometers to the high standards required by applications such as those listed above, whether the equipment is a simple mercury thermometer, a highly sophisticated combined thermo-hyrometer or a contact-less Infra-Red or Laser thermometer.
